Mumbai Rain News: Only 103 mm Rainfall Recorded So Far in August

Mumbai, 14th August 2025: The monsoon may have arrived early in Mumbai this year, but overall rainfall has remained significantly below normal. Over the past two months, showers have been sparse, with brief spells at the end of June and in July making up most of the season’s total so far. July ended with a clear rainfall deficit, and August began with several dry days.

So far this month, Mumbai has not witnessed any heavy showers — only 1 to 3 mm of rain has been recorded on a given day. As a result, the city continues to wait for the kind of heavy rains that are typical for this time of year.

According to the India Meteorological Department (IMD), Mumbai is expected to receive normal rainfall in August, with intensity likely to pick up in the latter half of the month. Normally, the city receives an average of 1,048.5 mm rainfall in August. To meet this average, 945.5 mm of rain is still required across both Colaba and Santacruz weather stations.

Rainfall Deficit in July
July also failed to bring adequate rainfall. IMD data shows that between July 1 and 31, the Colaba station recorded 378.4 mm of rain, while the Santacruz station registered 790.6 mm. Compared to July last year, Colaba received 355.7 mm less rain, and Santacruz recorded a deficit of 65.1 mm.

Record Rainfall in May
In contrast, Mumbai experienced unprecedented rainfall in May this year. Between May 1 and 31, the city recorded a total of 881.6 mm of rain — the highest May rainfall in 107 years. Pre-monsoon showers, followed by the early arrival of the monsoon, contributed to this unusual weather pattern.

In May alone, the Colaba station recorded 503.2 mm of rain, while Santacruz received 378.4 mm. This exceptional early-season rainfall was in sharp contrast to the subdued rains seen in July and so far in August.
