The India Meteorological Department (IMD) has issued a yellow alert for hot and humid conditions affecting Mumbai and its neighboring districts of Thane, Palghar, and Raigad on Tuesday, April 22, 2025. This warning comes as the region braces for a significant increase in temperatures over the next couple of days, although relief is expected after Thursday.
While Maharashtra is experiencing a heatwave, with areas like Chandrapur recording a scorching 45.6 degrees Celsius on Monday, April 21, Mumbai has remained relatively cooler. On the same day, both the Santacruz and Colaba coastal observatories in the city registered normal maximum temperatures around 33.5 degrees Celsius.
Interestingly, minimum temperatures in Mumbai dipped below seasonal averages on Tuesday, with the Santacruz observatory reporting a low of 23.5 degrees Celsius, which is 1.4 degrees below normal. Adding to the comfort, humidity levels have also seen a significant drop, hovering around 65 percent, nearly 6 percent lower than the usual average.
Meteorologists attribute the current weather patterns to prevailing northwesterly winds at lower atmospheric levels. These winds have helped maintain moderate temperatures in Mumbai over the past few days. However, beginning Tuesday, the IMD has issued a yellow alert for hot and humid conditions in select pockets of Mumbai and adjoining districts. While the alert for Mumbai is limited to Tuesday, areas like Thane and Raigad may continue to experience these conditions until at least Wednesday, April 23, 2025.
As for the forecast, the IMD predicts that Mumbai could see maximum temperatures rise to over 36 degrees Celsius between Tuesday and Wednesday, marking a notable jump from recent days. Meanwhile, neighboring Thane is expected to experience even higher temperatures, potentially reaching up to 39 degrees Celsius by midweek.
Mahesh Palawat, Vice-President of Meteorology at Skymet Weather Services, explained that the anticipated spike in temperatures for the next two to three days is due to an influx of northerly winds from warmer regions. “Currently, northwesterly winds from the seas have controlled temperatures in Mumbai. However, the region will soon see the arrival of northerly winds, which will result in a temperature spike over the next two to three days,” Palawat stated.
Despite the rising temperatures, it's important to note that no heatwave has been declared in the city. The IMD's forecast bulletin indicates that after Thursday, temperatures are expected to ease again, with maximums likely settling around 34 degrees Celsius in Mumbai.
This weather pattern has drawn attention not only for its immediate impact on daily life but also for how it reflects broader climatic trends. The IMD's yellow alert serves as a reminder of the ongoing challenges posed by extreme weather conditions, particularly in urban areas where heat retention can exacerbate discomfort.
With the Air Quality Index (AQI) in Mumbai currently standing at 77, categorized as 'Satisfactory', individuals with respiratory conditions are advised to limit outdoor activities and wear masks, especially as temperatures rise. The IMD continues to monitor the situation closely, providing updates as conditions evolve.
As the city prepares for the heat, local authorities are likely to remind residents of the importance of hydration and staying cool, particularly during peak hours. The combination of rising temperatures and humidity can lead to discomfort and health risks, making awareness and preparedness essential.
In summary, as Mumbai and its surrounding regions brace for a hot spell, the IMD's yellow alert highlights the need for vigilance and adaptability in the face of changing weather patterns. With a potential respite on the horizon, residents are encouraged to take precautions while enjoying the brief interlude of milder conditions that the city has experienced.
