As the summer of 2025 intensifies, residents of Lucknow and Ambedkar Nagar (my home district) should brace for a hotter-than-normal season, according to detailed forecasts based on IMD advisories and verified weather data. Here's a comprehensive outlook for the upcoming months:
May 2025: Scorching and Dry
Temperature:
May is historically the hottest month. Lucknow usually records an average high of around 39.2°C and low of 26.1°C, while Ambedkar Nagar (proxied by Ayodhya) averages 38.2°C / 25.7°C.
This year, the Indian Meteorological Department (IMD) predicts above-normal heat, with many days crossing 40°C. Expect daytime highs around 39–40°C and warm nights between 25–27°C.
Heatwaves:
Above-normal heatwave activity is projected. News outlets like The Economic Times and Times of India warn of “extreme heat” across Uttar Pradesh, especially in April–June. IMD has already issued heatwave alerts in late April, and these are expected to continue throughout May.
Rainfall & Monsoon Onset:
May is typically dry. Lucknow averages ~17 mm of rain, while Ambedkar Nagar sees around ~26 mm. Any showers will likely be isolated pre-monsoon thunderstorms.
The southwest monsoon is expected to reach Uttar Pradesh by mid-to-late June.
Humidity:
Expect dry heat with average relative humidity around 38%–43%. The air will feel very arid, making the heat even harsher.
Warnings/Advisories:
Authorities are expected to issue heat advisories, adjusting school timings and emphasizing hydration. With double the usual heatwave days predicted, caution is highly recommended.
June 2025: Waiting for the Monsoon
Temperature:
June normally sees a slight temperature drop (Lucknow ~37.1°C, Ambedkar Nagar ~36.1°C). However, above-normal heat is still expected, especially in early June.
Highs will hover around 37–39°C, with nights warmer at 27–29°C.
Heatwaves:
The first half of June could still experience significant heatwave events until the monsoon arrives.
Rainfall/Monsoon:
June is the month of monsoon onset. Early June remains mostly dry, but rainfall will start increasing around mid-June.
Lucknow typically records ~129 mm and Ambedkar Nagar ~156 mm of rain during June.
IMD forecasts indicate a normal to slightly above-normal monsoon, though some pockets might receive less rain.
Humidity:
As rains approach, humidity will rise significantly, often reaching 60–70% by late June, leading to sticky, muggy nights.
Warnings/Advisories:
Early June will still see heat alerts, but the focus will shift to heavy rain warnings as the monsoon progresses.
July 2025: Rainy, Humid Relief
Temperature:
With the monsoon fully active, July will be much cooler.
Daytime highs will stabilize around 32–33°C, with muggy nights near 26–27°C.
Rainfall:
July is the wettest month.
Lucknow typically receives ~310 mm and Ambedkar Nagar around ~353 mm of rainfall.
Most days will be wet or stormy, providing major relief from the earlier heat.
Humidity:
Humidity will be extremely high, around 79–82%, resulting in a sticky environment between rain spells.
Warnings/Advisories:
The major concern will shift from heat to flooding risks. Heavy rain advisories, localized flooding, and lightning warnings will be common. It’s advisable to stay updated with local weather bulletins during this time.
Historical Comparison
Across May, June, and July 2025, temperatures are expected to be warmer than historical averages based on 1991–2020 climatology.
While May and early June will bring intense heat, the arrival of the monsoon by mid-to-late June will slowly moderate temperatures.
July will be a high-rainfall, humid month, typical of the monsoon season in Uttar Pradesh.
