A noticeable atmospheric transition is underway across Rajasthan as the southwest monsoon steadily retreats from the desert state. Favorable atmospheric parameters have developed, speeding up the withdrawal process across multiple districts over the coming two to three days. While the overarching pattern points toward dry and clear conditions, the departing monsoon will deliver scattered light showers and localized thunder activity to a few eastern divisions. On September 21, isolated rainfall is expected in eastern Rajasthan, while the vast expanse of the western desert region transitions into a prolonged dry phase.
Current Monsoon Withdrawal Line and Favorable Conditions
The withdrawal line of the southwest monsoon has advanced steadily and is presently aligned through latitude 27.0° North and longitude 68.0° East, passing directly across Ramgarh, Mohangarh, Phalodi, Khajuwala, and extending up to latitude 29.5° North and longitude 71.5° East. Atmospheric conditions are entirely supportive of further retreat across additional districts of Rajasthan over the next two to three days. The same withdrawal trajectory is also creating ideal conditions for the monsoon to depart from adjacent regions in Punjab, alongside parts of Saurashtra and Kutch in Gujarat, clearing the path for dry continental air to dominate.
Localized Showers, Lightning, and Gusty Winds in Eastern Pockets
According to the meteorological assessment for September 21, light rainfall is anticipated at isolated spots within Kota, Udaipur, and Ajmer divisions. This precipitation pattern will not blanket all districts within these divisions; rather, it will remain confined to scattered pockets. Specific caution surrounds Baran, Jhalawar, Kota, and Pratapgarh, where cloud development could be accompanied by thunder, cloud-to-ground lightning strikes, and gusty surface winds moving at velocities between 30 and 40 kilometers per hour. Residents in these vulnerable areas are urged to exercise precautions and take shelter indoors when sudden storms develop.
Dry Conditions and Escalating Daytime Heat Across Western Rajasthan
Across western Rajasthan, encompassing the vast arid stretches of Jodhpur and Bikaner divisions, predominantly dry weather is forecast to prevail for the next 5 to 7 days. Eastern Rajasthan is likewise slated to experience dry weather across most pockets for the next 5 to 6 days. As the cloud shield dissipates and skies turn clear, solar radiation is intensifying rapidly across the western territory. Although recent spells of rainfall had provided temporary respite by driving down maximum temperatures over the past two days, the reduction in rainfall activity is set to trigger a fresh mercury spike. Barmer recently clocked the state's highest maximum temperature at 39.2 degrees Celsius, signaling that the dry phase will bring elevated daytime heat back to the western belt.
Outlook From September 22 to September 25 and Western Disturbance Impact
By September 22, rain activity will dwindle further, with only isolated pockets in Udaipur division likely to receive lingering showers, while the rest of Rajasthan stays dry. On September 23 and 24, completely dry and typical post-monsoon weather will cover virtually the entire state, keeping western districts devoid of rain. However, a slight atmospheric disturbance is slated for September 25, when a weak western disturbance will partially influence northern sectors. Under its influence, districts such as Sri Ganganagar, Hanumangarh, northern Bikaner, and Churu may witness isolated thunder, brisk winds, and localized rain. Local convective clouds could also alter weather patterns across pockets of northern, eastern, and central Rajasthan, bringing sporadic showers accompanied by gusty winds to Kota and Bharatpur divisions, even as general conditions across the state remain predominantly normal.
Late September and Extended October Projections
Weather conditions on September 26 and 27 will revert to calm and stable patterns across most of Rajasthan, with no significant precipitation on the horizon. Towards the end of the month, on September 29 and 30, localized cloud formations could spark isolated light rainfall across one or two locations in northern, eastern, and central parts of the state. Looking further ahead into October, the period between October 1 and October 7 is expected to see largely normal weather, punctuated by occasional gusts of brisk wind. Extended forecasts indicate the possible activation of two successive western disturbances during the third and fourth weeks of October, whose exact impact will depend heavily on evolving meteorological conditions closer to that window.
