April is usually the doorway to summer, but this year the temperature line is bending in some surprising ways. If you’re planning trips, outdoor work, or just want to know whether to crank the AC, here’s a quick rundown of what’s happening across the country.
Delhi-NCR has already nudged above 35 °C on several days, with humidity tipping the heat index into the high 40s. The latest IMD forecast shows daytime peaks of 38‑40 °C for most of April, followed by cooler nights barely dropping below 26 °C. This pattern mirrors the early‑summer spikes we saw in March 2024, but the rise is steadier, not just a one‑off spike.
What does this mean for you? Stay hydrated, wear light cotton, and avoid outdoor workouts after 4 pm when the sun is strongest. The city’s AQI has been hovering around 80‑90, so limiting heavy traffic exposure on hot afternoons helps both your lungs and your skin.
Along the Arabian Sea, places like Mumbai are seeing a different story. While the city still faces humid conditions, temperatures are stuck around the low 30 °C range, thanks to sea breezes that push heat offshore. The IMD’s coastal model predicts occasional showers that will keep daytime highs from breaching 33 °C.
For residents and tourists, that means you can enjoy evening strolls on Marine Drive without sweltering. Pack a light jacket for the occasional cool gust after sunset, especially if you’re heading to the outlying suburbs where the inland heat picks up.
Overall, April 2025 is shaping up as a mixed bag: scorching heat in the north, comfortable warmth on the west, and occasional thunderstorms that could bring temporary relief. Keep an eye on daily updates, stay cool, and plan activities around the cooler early mornings or late evenings when the temperature dip makes a real difference.
