Early May will bring another resurgence of dangerous heat across India as the nation continues to wait for the summer monsoon to bring lasting heat relief.
High temperatures through Thursday will average within a degree of 40 C (104 F) across New Delhi and the National Captial Region.
While still seasonably hot, the current heat is not as extreme as the 45 C (113 F) that made for New Delhi’s hottest April day since 2010 on 20 April.
High pressure will build back across India later this week, allowing temperatures to soar once again.
The heat is expected to reach dangerously high levels this weekend into next week. The number of communities reaching or exceeding 43 C (110 F) will increase from southern Uttar Pradesh and eastern Madhya Pradesh to Jharkhand and western Odisha.
"Temperatures will once again surge past 43 C (110 F) in New Delhi," AccuWeather Senior Meteorologist Jason Nicholls said.
Temperatures in New Delhi could reach the highest levels of the year so far early next week with highs ranging from 43-46 C (110-115 F).

Highs of 43-46 C (110-115 F) will also be common throughout northwestern, north-central and eastern India, away from the coast. The hottest locations will exceed 46 C (115 F).
The only relief from the heat will be isolated thunderstorms across northern and northwest India, however, these storms will be very isolated and most communities will remain dry and hot.
The elderly and children are most susceptible to heat-related illness, especially when nighttime temperatures remain well above-normal levels, not allowing homes to cool from the extreme daytime heat.
Staying hydrated and avoiding extended exposure to the sun and heat during the daytime are crucial, especially during the hottest parts of the day.
In Mumbai, actual temperatures will continue to be held well below 38 C (100 F) this week. However, the heat will be just as dangerous as high humidity levels will send AccuWeather RealFeel® Temperatures to 43 C (110 F) daily.
No lasting relief from the heat is expected until the monsoon arrives, which means dangerous heat will be a concern into June.
The monsoon typically spreads from southeast to northwest across the country during the month of June, and no significant change from normal timing is expected this year.
"The arrival of the monsoon will be in early June across southern India, but is not expected to reach the National Capital Region until late June or early July," said Nicholls.
"A near- to slightly below-normal monsoon this year overall [is expected], with the greatest deficits across southeastern and northwestern India," he said.
