Delhi-NCR Braces for Severe Heatwave: May 23-28, 2026

Delhi-NCR is expected to remain under a severe heatwave from 23 to 28 May 2026. Rainfall activity is limited. Beyond this short-lived spell, hot and dry conditions are likely to prevail across the region, with only minor fluctuations in temperature and no significant or sustained respite from the heat.

Delhi and surrounding regions are expected to remain under strong heatwave conditions from 23 May to 28 May 2026, although intermittent thunderstorm activity has brought brief and localized rain relief in parts of the NCR. Despite these short-lived weather disruptions, the broader pattern continues to be dominated by hot and dry conditions, with only limited cooling effects following thunderstorm spells.

Synoptic Systems Influencing Delhi Weather

A Western Disturbance persists as a cyclonic circulation over north Pakistan and neighbourhood at around 3.1 km above mean sea level, along with a trough in the middle and upper tropospheric westerlies near longitude 75°E north of latitude 25°N.

In addition, an upper air cyclonic circulation remains active over northwest Uttar Pradesh, extending up to 1.5 km above mean sea level, with an associated trough extending towards interior Odisha via East Uttar Pradesh and Chhattisgarh.

Despite these systems, they are not expected to bring significant rainfall or heat relief to Delhi in the short term.
