Weather Kolkata: A Complete Guide to Climate and Forecasts

Introduction

Weather Kolkata conditions influence daily commuting, outdoor activities, travel plans, festivals, and everyday comfort. Located in West Bengal in eastern India, Kolkata experiences a tropical wet-and-dry climate, with hot summers, a humid monsoon season, and comparatively pleasant winters. Temperatures, humidity, rainfall, and cloud cover can change considerably throughout the year, making regular weather updates useful for residents and visitors.

During October, the city generally transitions from the southwest monsoon toward drier post-monsoon conditions, although occasional showers may continue. On October 14, 2026, the available forecast indicates warm, mostly cloudy conditions, with a daytime high near 34°C and a chance of rain. The outlook also suggests possible afternoon showers on October 15 and 16. Conditions can vary between neighbourhoods, so forecasts should be checked before important journeys or outdoor plans.

Understanding Kolkata’s climate helps people choose suitable clothing, prepare for rainfall, manage heat exposure, and select appropriate times for sightseeing. This guide explains seasonal weather patterns, temperature changes, rainfall, forecast interpretation, and practical ways to prepare for changing conditions.

Understanding the Current Weather Kolkata Forecast

Checking the latest forecast is a practical way to understand how the day may develop. Current conditions describe what is happening now, while hourly and extended forecasts estimate what may happen later.

For October 14, 2026, the available forecast indicates temperatures around 26°C to 34°C, with clouds increasing during the afternoon. The chance of rain is higher during the day than in the evening. October 15 may bring afternoon showers, while October 16 also carries a possibility of rain. These predictions can change as weather systems develop, so they should be treated as guidance rather than guarantees.

When reviewing a weather report, pay attention to several details:

• Maximum temperature: The expected highest temperature during the day.

• Minimum temperature: The expected lowest temperature, usually overnight or early morning.

• Rain probability: The forecast likelihood of precipitation for the specified period.

• Humidity: The amount of moisture in the air, which affects how warm conditions feel.

• Wind speed: Information that helps people assess comfort and potential travel disruptions.

• Weather warnings: Official alerts about thunderstorms, heavy rainfall, lightning, or other hazards.

Looking at these factors together provides a clearer picture than checking temperature alone.

Kolkata’s Climate Throughout the Year

Kolkata’s climate is strongly influenced by its eastern Indian location, proximity to the Bay of Bengal, and seasonal monsoon circulation. Moisture from the bay contributes to humid conditions, while summer temperatures can make afternoons uncomfortable.

The year can broadly be divided into summer, monsoon, post-monsoon, and winter periods. These seasons do not always begin or end on precisely the same dates. Atmospheric conditions can shift from one year to another, affecting rainfall and temperature.

Summer is generally hot, with warm mornings and increasingly uncomfortable afternoons. The monsoon brings frequent rain, cloud cover, and persistent humidity. The post-monsoon period often features gradually changing rainfall patterns, while winter typically provides cooler mornings and more comfortable afternoons.

These seasonal differences affect transportation, clothing choices, outdoor recreation, and household routines. Understanding the broad climate pattern helps people prepare in advance, but checking the current forecast remains essential because unusual weather can occur in any season.

Seasonal Temperature and Rainfall Patterns

The following table provides a general guide to Kolkata’s seasonal conditions. The temperature ranges are approximate climate-planning estimates, not a live forecast or guaranteed historical averages.

Seasonal boundaries can overlap, and the weather may differ between individual years. Rainfall during the monsoon is particularly important because heavy showers can affect roads, drainage, and public transport.

October and November are often transitional months. Although conditions may become drier after the monsoon, low-pressure systems and moisture from the Bay of Bengal can still produce rainfall. Consequently, travellers should avoid assuming that every autumn day will be completely dry.

Winter generally offers more comfortable daytime conditions, although temperatures can fluctuate. During summer, meanwhile, heat and humidity make hydration and shade particularly important.

Summer Weather in Kolkata

Summer usually develops from March and becomes more intense during April and May. Daytime temperatures can rise into the middle or upper 30s Celsius, with hotter conditions possible during heat episodes.

High humidity makes the heat feel more uncomfortable because sweat evaporates less efficiently. People walking through crowded markets, waiting at bus stops, or travelling without air conditioning may experience greater discomfort than those staying indoors.

Pre-monsoon thunderstorms can also occur during this period. These storms may bring short periods of heavy rain, lightning, gusty winds, and temporary travel disruption. A hot afternoon therefore does not necessarily mean the evening will remain dry.

To manage summer conditions, drink water regularly, wear breathable clothing, use sun protection, and schedule demanding outdoor activities for cooler hours when possible. Children, older adults, outdoor workers, and people sensitive to heat should take additional precautions.

Checking the daily temperature and any official heat-related advisories is particularly useful during unusually hot periods. Avoid relying on yesterday’s weather because temperatures and storm conditions can change quickly.

Monsoon Rainfall and Humidity

The southwest monsoon usually affects Kolkata from June through September. During this period, moisture-laden winds bring repeated spells of rain, extensive cloud cover, and high humidity.

Rainfall can vary considerably from one day to another. Some days feature intermittent showers, while others may experience prolonged or intense rainfall. Thunderstorms and weather systems developing over the Bay of Bengal can influence the timing and strength of precipitation.

Heavy rain can slow traffic, reduce visibility, create waterlogged streets, and disrupt local transportation. People travelling to railway stations, offices, airports, or appointments should allow extra time when significant rainfall is forecast.

Useful monsoon precautions include:

• Carrying a compact umbrella or raincoat.

• Wearing footwear suitable for wet surfaces.

• Protecting phones, documents, and electronic equipment from water.

• Avoiding flooded roads and underpasses.

• Checking official alerts before travelling during thunderstorms.

Humidity may remain high even between showers, making the atmosphere feel warmer than the measured temperature suggests. Drying clothes can also take longer, and damp indoor spaces may require better ventilation.

Although rainfall supports regional water resources and vegetation, intense downpours require careful planning. Following local advisories is safer than assuming a familiar route will remain passable.

Post-Monsoon Weather and October Conditions

October is an important transition period for Kolkata. The southwest monsoon withdraws, but atmospheric moisture and systems associated with the Bay of Bengal can still produce occasional rain.

For this reason, weather Kolkata searches often become especially useful during October. Residents may experience warm afternoons, humid conditions, changing cloud cover, and intermittent showers even when the broader seasonal pattern is becoming drier.

The latest available forecast for October 14–16, 2026, indicates daytime temperatures around 33–34°C, with possible afternoon showers on October 15 and 16. These conditions are consistent with the need to monitor short-term forecasts during seasonal transitions.

October is also associated with important cultural celebrations in West Bengal. People visiting pandals, meeting family, or attending public events often spend long periods outdoors. Checking rainfall chances before leaving home can help with choosing travel times and carrying suitable clothing.

However, seasonal expectations should never replace current information. A dry morning may be followed by an afternoon shower, while a forecast rain event may weaken or shift. Hourly updates provide useful guidance for planning activities around these changes.

Winter Weather and Comfortable Travel

Winter, generally spanning December through February, is often considered one of the most comfortable periods for exploring Kolkata. Compared with summer, daytime conditions are usually milder, humidity may feel less oppressive, and mornings can be noticeably cooler.

Visitors can enjoy walking through historic neighbourhoods, exploring markets, visiting museums, and spending time in parks without facing the same persistent summer heat. Outdoor photography and sightseeing may also be more comfortable during suitable weather.

Nevertheless, winter does not mean temperatures remain identical throughout the season. Cold spells can produce cooler mornings, while sunny afternoons may feel relatively warm. Clothing that can be adjusted throughout the day is therefore a sensible choice.

Fog or reduced visibility may occasionally affect regional transport conditions. Travellers with early flights or train departures should check service updates alongside the forecast instead of assuming that favourable daytime weather guarantees smooth travel.

Winter is also a useful time to plan longer outdoor itineraries. Even so, checking the forecast before visiting attractions helps travellers make informed decisions about timing, clothing, and transportation.

How Weather Affects Daily Life in Kolkata

Weather influences more than personal comfort. It affects commuting, work schedules, school activities, shopping, tourism, and the operation of public spaces.

During heavy rainfall, roads may become congested, journey times may increase, and some streets may experience temporary waterlogging. Commuters can benefit from leaving earlier, checking transport updates, and keeping alternative routes in mind.

Heat presents a different challenge. People travelling on foot or using crowded public transportation may experience greater discomfort during the hottest part of the day. Drinking water, wearing breathable clothes, and taking breaks in shaded or cooler spaces can help.

Weather can also influence household activities. Rain may delay laundry drying, affect outdoor maintenance, and increase the need to protect stored belongings from moisture. During thunderstorms, securing loose outdoor items and staying away from exposed locations are sensible precautions.

Businesses, event organisers, and delivery services can also benefit from checking forecasts. Planning around rain or heat may reduce avoidable delays and improve safety for staff and customers.

Weather Kolkata Forecasts for Travel Planning

A forecast is most useful when it informs a specific decision. Instead of simply checking whether the day will be sunny or rainy, consider when and where you will be travelling.

For example, someone planning a morning market visit may be more concerned about early conditions, while a person attending an evening event should check the forecast for the hours surrounding that event.

Before leaving home, consider the following steps:

1. Check the daily forecast and hourly precipitation chances.

2. Review official warnings for thunderstorms, lightning, or heavy rain.

3. Allow extra travel time when wet roads or congestion are possible.

4. Carry water during hot weather and rain protection when showers are forecast.

5. Recheck conditions before long journeys or outdoor events.

Visitors arriving at Netaji Subhas Chandra Bose International Airport should also monitor flight updates directly through their airline. A weather forecast alone cannot confirm whether a particular flight will be delayed.

For official meteorological information, consult the India Meteorological Department (IMD). Its forecasts and warnings provide useful context for interpreting local conditions. Forecasts become less certain farther into the future, so use longer-range outlooks for broad planning and short-range updates for immediate decisions.

Air Quality, Humidity, and Personal Comfort

Temperature alone does not explain how comfortable a day feels. Humidity, wind, sunlight, and air quality can all affect outdoor experiences.

High humidity reduces the efficiency of sweat evaporation, making warm conditions feel more oppressive. People may therefore feel uncomfortable even when the thermometer shows a temperature that appears manageable.

Air quality is another important consideration. Pollution levels can vary with emissions, atmospheric conditions, wind, and other factors. A weather forecast cannot substitute for an air-quality reading, and clear skies do not necessarily mean the air is clean.

When air quality is poor, people who are sensitive to pollution may need to reduce prolonged or strenuous outdoor activity. Check a reliable local air-quality index before exercising outside, especially during periods of reported unhealthy pollution.

On October 14, 2026, the available weather report flags very unhealthy air quality in Kolkata. Because air-quality conditions can change, check the latest local reading before making decisions about outdoor exercise or extended exposure.

Staying hydrated, taking breaks from heat, and choosing appropriate activity times can improve comfort. People who develop concerning symptoms during heat or poor air quality should move to a safer environment and seek appropriate medical advice.

Conclusion

Weather Kolkata conditions change with the seasons, making forecasts useful for residents, commuters, businesses, and visitors. Hot summers, humid monsoon months, transitional autumn conditions, and milder winters each bring different planning requirements.

Understanding temperature, rainfall probability, humidity, wind, and air quality provides a more complete picture of the day’s conditions. A forecast can help you choose clothing, prepare for showers, schedule outdoor activities, and allow extra time for journeys.
