Mumbai Swelters: October Heat Breaks 13-Year Record

Mumbai recorded an exceptionally warm start to October, as the Colaba observatory registered a high of 37.4°C on Friday. This marks the highest October temperature in south Mumbai in at least 13 years, significantly exceeding the normal by 5.6°C.

The unusual heat is linked to the ongoing transition from the southwest monsoon. Shifting wind patterns from westerlies to easterlies and an anti-cyclone near the city have contributed to warmer daytime conditions.

Further heat is anticipated, with the India Meteorological Department forecasting daytime temperatures to hover between 35°C and 37°C for the next two to three days. High humidity levels are expected to make these conditions feel even more oppressive.

While this 37.4°C reading is notable for its early occurrence in October, it remains below the all-time October record of 39.5°C set in 1968. Meanwhile, other major cities like Delhi and Chennai are also experiencing temperatures in the mid-30s, though Bengaluru remains comparatively cooler.

As the post-monsoon pattern becomes more established, Mumbai's weather is expected to gradually shift. However, for the immediate future, residents should prepare for continued warmth and humidity.
