Now, let’s get into the details and paint a picture of what September 27, 2025, might look like in Kolkata! Understanding the seasonal context is crucial. September in Kolkata typically marks the tail end of the monsoon season. This means we can expect a mix of conditions: some days might be quite wet with heavy showers, while others could be humid but relatively dry. Temperatures generally range from the high 20s to the low 30s Celsius (around 80-90°F). Humidity tends to be high, making it feel warmer than the actual temperature. So, pack light, breathable clothing! Keep a small, foldable umbrella or a light raincoat handy. Kolkata's weather can be unpredictable during this time, and it's always better to be prepared for a sudden downpour. Also, consider wearing shoes that can handle wet conditions, as you might encounter puddles and damp streets.

Expected Temperature

Alright, let's talk temperatures! For September 27, 2025, in Kolkata, we can anticipate a range between 27°C to 32°C (81°F to 90°F). That's your daytime high, so expect it to be pretty warm, especially when you factor in the humidity. Now, this isn't just a random guess; we're basing this on historical data for Kolkata in late September. Typically, this time of year sees a gradual decrease in the monsoon's intensity, but the heat still lingers. Evenings might bring a slight respite, but don't expect a significant drop. You'll still feel the warmth, so keep those lightweight clothes ready. But what does this temperature range really mean for you? Well, if you're planning to be outdoors, make sure you stay hydrated. Carry a water bottle and sip on it regularly. Seek shade whenever possible, especially during the hottest part of the day, usually from noon to mid-afternoon. And, of course, sunscreen is a must! Even on cloudy days, the sun's rays can be quite strong. If you're someone who isn't used to humid conditions, take it easy. Avoid strenuous activities during peak heat hours. Kolkata offers plenty of indoor attractions, like museums and shopping malls, where you can escape the heat. Air conditioning will be your best friend! Also, keep an eye on the actual temperature readings on that day. Weather forecasts can give you a good estimate, but real-time data will help you adjust your plans accordingly. Numerous weather apps and websites provide up-to-the-minute information. Remember, these temperatures are just an estimate based on historical trends. Actual conditions may vary, so always check a reliable weather source closer to the date for the most accurate forecast. This helps in making informed decisions about your activities and ensures you're well-prepared for the day.

Probability of Rainfall

Now, let's get to the big question: Will it rain on September 27, 2025, in Kolkata? Since it's still technically the tail end of the monsoon season, there's a decent chance. Historically, Kolkata sees a gradual decrease in rainfall throughout September, but sudden showers are still quite common. So, I'd say there's a moderate probability – maybe around 40-60% – of some rainfall on that day. This could range from a light drizzle to a heavy downpour, so it's best to be prepared for anything. What does this mean for your plans? Well, if you're organizing an outdoor event, have a backup plan in place. A covered area or an alternative indoor venue would be a good idea. And for everyone else, carrying an umbrella or a raincoat is a must. You don't want to get caught in a sudden shower! But remember, rain in Kolkata during this time is usually not continuous. You might experience a heavy downpour for an hour or two, followed by clear skies. So, don't let the possibility of rain completely ruin your plans. Keep an eye on weather updates throughout the day. Many weather apps provide hourly forecasts, so you can see when the rain is expected and plan your activities accordingly. And don't forget about the traffic! Rain in Kolkata can often lead to traffic congestion, so factor in extra travel time if you're heading out. Public transportation might also be affected, so check for updates before you leave. To summarize, while it's impossible to say for sure whether it will rain, the odds suggest you should be prepared for some wet weather. Keep an umbrella handy, have a backup plan for outdoor activities, and stay informed about the latest weather updates. That way, you can enjoy your day in Kolkata, rain or shine!

Humidity Levels

Alright, let’s dive into humidity levels, something Kolkata is pretty famous for! On September 27, 2025, expect the humidity to be quite high, likely hovering around 70-85%. For those not used to it, that can feel pretty sticky and uncomfortable. High humidity means the air is saturated with moisture, making it harder for your sweat to evaporate, which is how your body cools down. So, even if the temperature isn't extremely high, you might feel hotter than it actually is. What can you do to cope with the humidity? First, wear loose-fitting, breathable clothing. Cotton and linen are your best friends here. Avoid synthetic fabrics, as they trap heat and moisture. Stay hydrated by drinking plenty of water throughout the day. Avoid sugary drinks, as they can actually dehydrate you. Take it easy and avoid strenuous activities during the hottest and most humid parts of the day. Seek out air-conditioned spaces whenever possible. Malls, museums, and cafes can offer a welcome respite from the humidity. If you're staying in a hotel, make sure your room has air conditioning. A fan can also help circulate the air and make you feel cooler. Be mindful of how your body is feeling. If you start to feel dizzy, nauseous, or excessively tired, find a cool place to rest and drink water. High humidity can also affect your skin. You might find that your skin feels sticky or oily. Use a light, oil-free moisturizer to keep your skin hydrated without clogging your pores. Powder can also help absorb excess moisture. To put it simply, be prepared for a humid day! Take steps to stay cool, comfortable, and hydrated. With a little planning, you can minimize the effects of the humidity and still enjoy your time in Kolkata.

If you're planning any outdoor activities, the wind shouldn't be a major factor. It might even be beneficial, providing a cooling effect.
