Because of mostly clear skies until the afternoon, “Day temperatures are going up.
Commenting on the rise in daytime temperatures, IMD scientist SD Sanap said clear skies during the first half of the day were allowing temperatures to rise before cloudiness developed in the afternoon. When there is less rainfall and more sunlight, temperatures are bound to increase,” he said. He said while moisture remains present in the atmosphere during the monsoon, it does not necessarily result in rainfall unless there is sufficient moisture incursion or a strong monsoonal flow.
Clouding develops later, but by then the surface has already heated up. The primary reason is lack of rainfall. “During the monsoon season, there will always be some humidity and moisture in the atmosphere. Moisture incursion continues in varying amounts, but it does not necessarily result in rainfall every time. Unless there are very strong monsoonal winds or a substantial amount of moisture incursion, rainfall may not occur. However, when moisture is already present in the atmosphere and we get a lot of sunlight instead of cloudy weather, it creates hot and humid conditions and makes us feel more uncomfortable. When there are clouds, less sunlight reaches the surface, so we do not feel the discomfort as much, even though moisture is present in the atmosphere,” he added.
