Mumbai:

The current unseasonal "heat Wave" Temperatures persisted on 23rd..with Santacruz recording 37.2c...5c above normal. Mumbai was the 4th hottest in India as shown below

We can expect this till 26th as mentioned.

However, the "Real Feel " temperature is much less...around 35c, as the humidity in the afternno is only 26%, very much less for a coastal city.

We feel hot and humid in April/may in Mumbai as the temperature may be around 33/34c, but humidity is at 85% in May. So "Real feel " Temperatures could be as high as 38/39c in April/May.
