Key Takeaways:
- Delhi may record its highest temperature of July today, touching around 39°C.
- True monsoon rainfall is likely to remain absent for the next couple of days.
- Multiple weather systems are expected to bring the monsoon trough closer to Delhi from July 20.
- Temperatures will ease into the lower 30s with regular showers expected during the second half of next week.
- Forecast Validity: Next 5 to 7 days.
True monsoon rains have remained elusive over the Delhi region for the last few days. Consequently, the day temperature breached the 38°C mark for the third consecutive day yesterday. This was over 3°C above normal. Today will be no better, and the mercury may touch 39°C, the highest of this month so far. Chances of rain are minimal, and the weather conditions are expected to improve, but not before the start of next week.
The seasonal east-west monsoon trough at the surface level is passing through Amritsar, Dehradun, Bareilly, Gorakhpur, and thence further eastward. The western end is maintaining a safe distance from Delhi, limiting any noticeable weather activity. Mostly clear skies and drier winds are increasing the heat factor and gradually raising the day temperature. The maximum temperature breaching 40°C during a dry spell in July is not very unusual. However, over the last four years, the capital city has remained immune to such extreme heat, and a similar situation is unlikely this month as well. The mercury is expected to dip more effectively from July 20 onwards and the relief is likely to spill over into the following week.
A fresh western disturbance is likely to arrive over the mountains on July 19. There will also be a cyclonic circulation over Southwest Rajasthan and the Pakistan region in the lower levels. By then, the low-pressure area over the Bay of Bengal and coastal Odisha is expected to move inland across Odisha and West Bengal, with a trough extending across the Indo-Gangetic Plains. Under the combined influence of these features, the monsoon trough—the primary trigger for Delhi rains—is expected to shift closer to the region. It may begin with a brief spell of light showers late on July 19 and gradually build up over the following week. Temperatures are likely to fall to the lower 30s, and short spells of intermittent showers may become a regular feature during the week. Significant rainfall is expected to provide much-needed relief from the warm and humid conditions, more noticeably during the second half of the week.
