Dharshni M May Weather Update 2025 is the peak of Tamil Nadu’s summer season, which is generally marked by high temperatures and dry conditions. However, May 2025 has caused some noticeable variances in weather patterns around the state. From improved heat waves to unexpected pre-monsoon showers, the region is seeing a dynamic change that demonstrates the changing character of seasonal weather, which may be influenced by larger climatic trends. lets look about Weather Shifts in Tamil Nadu— A Closer Look At May 2025
Persistent Heatwaves and Elevated Temperatures
Around the majority of Tamil Nadu, the month has been marked by extremely high daily temperatures. Maximum temperatures in districts such as Chennai, Madurai, Tiruchirappalli, and Ramanathapuram have ranged from 38°C to 41°C, with humidity levels adding to people’s suffering. The India Meteorological Department (IMD) verified that the number of heatwave days was higher than the seasonal norm, particularly in the interior regions.
This temperature increase is due to sustained dry northerly winds and clear skies, which allow direct solar radiation to exacerbate heat accumulation during the day. In coastal places such as Chennai, the heat is accompanied by high humidity, making the weather feel much hotter than the actual temperatures.
Pre-Monsoon Rainfall Offers Intermittent Relief
There have been widespread thunderstorms and pre-monsoon showers in several areas, especially in western Tamil Nadu, with the severe summer weather. In the first week of May, districts including Coimbatore, Nilgiris, Theni, and Dindigul reported modest rainfall and lightning activity, which helped to relieve the heat.
These showers are common during the pre-monsoon transitional period and are frequently brought on by moisture immigration from the Arabian Sea and local convective activity. The IMD predicts that isolated areas of light to moderate rainfall, particularly in hilly and nearby districts, will likely persist until mid-May.
Surprise Rainfall and Thunderstorms
In some areas of the state, especially those close to the Western Ghats and coastal regions, strong winds have been noticed in addition to rainfall. Warnings for farmers and fishermen have been issued due to noted wind speeds of up to 30 to 40 km/h.
Although strong winds are not particularly dangerous, they have the potential to remove weak trees, disturb outdoor activities, and raise the risk of fire in dry rural areas. The IMD keeps a careful eye on wind patterns and sends out local warnings as required.
Different Weather in Different Districts
Because of Tamil Nadu’s varied geography, different districts experience different climates. An overview of how several regions are doing in May 2025 is provided here:
• Chennai and the coastal regions are experiencing hot, muggy weather with evening clouds and scattered rainfall.
• Western Tamil Nadu (Coimbatore, Erode): Cooler nights and warm days with frequent rains.
