New Delhi is set to experience severe heatwave conditions starting April 17, 2025, with temperatures reaching a scorching 42.2°C during the day and dropping only to 30.3°C at night. The weather forecast indicates clear skies, low humidity at 17%, and light winds up to 14.8 km/h, making it one of the hottest days of the season.
The daytime temperatures will be most intense during midday hours, with the dry conditions offering no chance of rain. The low humidity levels mean residents will experience dry heat rather than muggy conditions.

Precautionary Measures

The weather conditions necessitate precautionary measures, especially during peak afternoon hours. Residents are advised to stay indoors, wear light clothing, and maintain proper hydration throughout the day.

Upcoming Week’s Forecast

The forecast for the upcoming week shows even more challenging conditions. Friday, April 18, will see temperatures rise to 43.5°C, marking it as the week’s hottest day.
The weekend will bring minimal relief, with temperatures reaching 42.5°C on Saturday and 41.3°C on Sunday. Wind speeds will increase to 20.9 km/h on Sunday, potentially providing slight relief from the heat.
Early next week shows temperatures stabilizing around 40°C on Monday and Tuesday, accompanied by extremely low humidity levels of 3%. Wednesday, April 23, will see temperatures climb back to 41.5°C.

Dry Conditions and Potential Risks

The week’s weather pattern is notable for its complete absence of precipitation. The combination of zero rainfall and humidity levels as low as 3% creates exceptionally dry conditions across the city.
These weather conditions pose potential health risks, particularly for vulnerable populations such as elderly citizens and children. Local authorities may issue heatwave warnings as the situation develops.
The dry conditions also increase the risk of wildfires, requiring additional caution when handling fire or flammable materials. The extreme dryness can lead to dehydration and skin issues among residents.

Recommendations for Outdoor Activities

For outdoor activities, early morning or late evening hours are recommended when temperatures are slightly lower. Protective measures such as sunscreen, sunglasses, and hats are essential for anyone venturing outside.

Wind Conditions and Overall Assessment

The wind conditions throughout the week will vary, with speeds ranging from 14.8 km/h to 20.9 km/h, offering minimal relief from the intense heat. These conditions represent an unusually hot and dry period for New Delhi during this time of year.
The combination of high temperatures and extremely low humidity creates challenging conditions that require careful attention to health and safety measures. Regular hydration and indoor shelter during peak heat hours remain crucial for residents.
