Rajasthan post-monsoon heat: Six districts cross 40°C, Barmer hits 43.6°C
Synopsis
Even as the monsoon withdraws from Rajasthan, six western districts crossed 40°C on 25 September, with Barmer hitting 43.6°C and Jaisalmer reaching 43.2°C — both the highest September readings in a decade. The anomaly, running nearly 7 degrees above normal in Barmer, signals an intensifying post-monsoon heat rebound in the state's arid belt.

A deep depression near northern Andhra Pradesh and southern Odisha is expected to weaken as it moves towards Chhattisgarh in the next 24 hours .
As the monsoon retreats from Rajasthan, a sharp heat rebound is gripping the state's western districts, with six districts recording temperatures above 40 degrees Celsius on Thursday, 25 September 2026. Barmer logged the state's highest reading at 43.6°C, while Jaisalmer followed at 43.2°C — both marking their highest September temperatures in the past 10 years, according to the Meteorological Centre.
Record-Breaking Readings Across Western Rajasthan
The heat was concentrated in the state's arid western belt. Jodhpur recorded 41.7°C, Bikaner reached 41.6°C, Churu touched 40.5°C, and Nagaur registered 40.3°C. All six districts exceeded the 40°C threshold on the same day, an unusual convergence for late September.
The departures from normal were striking. Barmer's mercury was 6.9 degrees above normal, Jaisalmer was 6.1 degrees above normal, Jodhpur stood 5.8 degrees above normal, and Bikaner was 4.2 degrees above normal. Churu came in at 3.6 degrees above normal. In contrast, the state capital Jaipur recorded a comparatively moderate 34.6°C, remaining below normal levels.
Decade-High September Temperatures in Barmer and Jaisalmer
The Jaipur Meteorological Centre confirmed that Thursday's readings in both Barmer and Jaisalmer were the highest for the month of September in the past 10 years. Jaisalmer's previous September peak during this period was 43.5°C, recorded in 2023, while Barmer's earlier high was 42.2°C, also set in 2023. Thursday's readings surpassed both benchmarks.
This comes amid a broader pattern of intensifying post-monsoon heat spells across northwest India, which climate observers note are becoming more frequent and severe as the transition season compresses.
Weather Forecast: Dry Days Ahead, Isolated Showers Later
Conditions across Rajasthan are expected to remain largely dry over the next two to three days. The Jaipur Meteorological Centre has forecast light to moderate rain at isolated locations in parts of the Bharatpur and Jaipur divisions and the Shekhawati region between 27 and 29 September. The Bikaner division may also receive isolated light rain on 28 and 29 September under the influence of a new Western Disturbance.
Deep Depression in Bay of Bengal Adds to Weather Watch
A deep depression located near northern Andhra Pradesh and southern Odisha is expected to move towards southern Odisha and Chhattisgarh over the next 24 hours, gradually weakening into a depression. While this system is not expected to directly affect Rajasthan, it underscores the complex meteorological transition underway across the subcontinent as the 2026 monsoon season draws to a close.
With the withdrawal progressing and no significant rain forecast for most of the state in the near term, western Rajasthan is set to endure continued intense heat before seasonal conditions ease.
Point of View
Where infrastructure to cope with late-season extremes is limited. The meteorological data is sharp; the public-response framing has not caught up.

Are Barmer and Jaisalmer's September temperatures record highs?
Yes. The Jaipur Meteorological Centre confirmed that both Barmer (43.6°C) and Jaisalmer (43.2°C) recorded their highest September temperatures in the past 10 years on 25 September 2026. Jaisalmer's previous decade-high was 43.5°C in 2023, and Barmer's was 42.2°C, also in 2023.

Why is Rajasthan experiencing such intense heat after the monsoon?
The monsoon withdrawal exposes western Rajasthan's arid terrain to rapid heating, as cloud cover and moisture levels drop sharply. This year, temperatures are running up to 6.9 degrees above normal in some districts, which meteorologists attribute to an unusually pronounced post-monsoon heat rebound.
Does the deep depression near Andhra Pradesh affect Rajasthan?
The deep depression near northern Andhra Pradesh and southern Odisha is not expected to directly affect Rajasthan. It is forecast to move towards southern Odisha and Chhattisgarh over the next 24 hours, gradually weakening into a depression.
