The heatwave that made Delhi’s nights the hottest in 14 years has finally broken. Night temperatures have dropped sharply, daytime highs have fallen from 46°C to 36°C, and another round of rain and thunderstorms is on the way. Here is today’s complete Delhi weather picture, the week ahead, and what you need to know before stepping out.asa
TODAY’S WEATHER — May 30, 2026
| Parameter | Reading |
| Morning Temperature (10 AM) | ~34°C |
| Today’s Expected Maximum | ~36°C |
| Night Temperature (Minimum) | ~24–25°C |
| Sky Condition | Partly sunny → clouding over by afternoon |
| Rain Probability Today | 44% — possible evening shower |
| Wind Speed | Gusty winds of 50–60 kmph expected, may reach 70 kmph in some areas |
| IMD Alert | Yellow Alert |
| Humidity | Rising through the day |
The Temperature Story — A 22°C Swing in 4 Days
To understand why today’s weather feels like relief, consider what Delhi went through this week:
| Date | Max Temperature | Night Temp | Condition |
| May 25 | 44°C | 30–32°C | Severe heatwave |
| May 26 | 44–46°C | 31–32°C | Hottest May night in 14 years |
| May 27 | 44–46°C | 30–31°C | Heatwave peak |
| May 28 | 43–45°C → dropping | Falling | Western Disturbance arrives — thunderstorms, 60–80 kmph winds |
| May 29 | 36–38°C | 26°C | Post-storm relief |
| May 30 (Today) | ~36°C | ~24–25°C | Partly sunny with evening rain risk |
This turbulent weather has brought massive relief, plunging daytime temperatures by a significant 7°C to 10°C over 48 hours.
The night-time shift is equally dramatic — from 32°C warm nights (when it felt like a furnace even at midnight) to a much more bearable 24–25°C tonight. Humidity is elevated, but the raw heat has broken.
What Made the Temperature Drop? — The Western Disturbance
A fresh Western Disturbance is affecting Northwest India from May 28, which has increased rain activity and reduced temperatures significantly.
A powerful combination of a Western Disturbance and moisture-laden easterly winds swept across the National Capital Region — producing thundersqualls and dust storms with gusty winds reaching 60 to 80 km/h.
What is a Western Disturbance? A Western Disturbance is an extratropical storm that originates over the Mediterranean or Atlantic Ocean and travels eastward across Central Asia and Pakistan, eventually bringing moisture and precipitation to Northwest India. During summer, they are weaker than winter Western Disturbances — but when they interact with moisture-laden winds from the Bay of Bengal and Arabian Sea, they trigger sharp thunderstorms, dust squalls and sudden temperature drops of the kind Delhi experienced on May 28–29.
Today’s Forecast — What to Expect Hour by Hour
The weather department has warned of very light to light showers with thunderstorms and lightning during the afternoon and evening. Gusty winds of 50–60 kmph may occur and could reach 70 kmph in some areas.
Morning (until noon): Partly sunny, warm but manageable at 32–34°C. Relatively lower humidity compared to recent mornings.
Afternoon (12 PM–4 PM): Clouds building. Temperature near peak 35–36°C. Increasing humidity. Avoid prolonged outdoor exposure.
Evening (4 PM–8 PM): Best chance of rain and thunderstorms. Lightning activity possible. Gusty winds 50–70 kmph. If heading out — carry an umbrella and plan for traffic disruption if storms hit.
Night: Cloudy, temperatures falling to 24–25°C. Significantly more comfortable than the past week.
7-Day Delhi Weather Forecast — May 30 to June 3, 2026
| Date | Max Temp | Rain Chance | Condition |
| Today (May 30, Sat) | ~36°C | 44% | Partly sunny, possible evening thunderstorm |
| Tomorrow (May 31, Sun) | ~32°C | 95% | Heavy rain, thunderstorms likely |
| June 1 (Mon) | ~35°C | Low | Clearing skies, warming begins |
| June 2 (Tue) | ~37°C | Negligible | Sunny, heat returning |
| June 3 (Wed) | ~38°C | Negligible | Hot, approaching uncomfortable again |
May 31 is the big rain day. With a 95% precipitation probability, Sunday is the day to stay indoors if possible, avoid low-lying areas that flood, and keep children and elderly away from open spaces during storm activity.
IMD Alerts — What the Colour Codes Mean
The India Meteorological Department issued an orange alert for Delhi and Noida, and a red alert for Gurugram during the peak weather disruption on May 28.
As of today (May 30), Delhi is under a Yellow Alert — the least severe of IMD’s three alert levels:
| Colour | Meaning | Action |
| Red Alert | Severe weather — take action immediately | Do not go out |
| Orange Alert | Be prepared — significant weather incoming | Avoid non-essential travel |
| Yellow Alert | Be aware — weather changes possible | Plan around potential disruption |
Today’s Yellow Alert means the risk is present but manageable. By May 31, IMD may upgrade this to Orange given the 95% rain probability.
Health Advisory — Heatwave Recovery + Rain Transition
Delhi has just emerged from one of the most intense May heat periods in recent memory. The sudden shift to rain and cooler temperatures brings its own risks:
During heat-to-rain transition:
- Viral infections rise — the body’s immunity adapts more slowly than the thermometer drops. Keep warm at night even with lower temperatures.
- Stay hydrated — even in cooler weather, the body is still recovering from heat stress. Dehydration risks persist.
- Lightning safety — with thunderstorms expected, avoid open fields, tall trees and elevated structures during storms.
- Traffic disruption — rain + gusty winds mean flooded underpasses, fallen branches and visibility drops. Allow extra commute time in the evening.
- Waterborne illness risk — post-rain waterlogging increases mosquito breeding and contamination risk. Use water purification as usual.
IMD Monsoon Outlook — When Is Delhi Getting the Monsoon?
Delhi’s monsoon arrival is typically expected around June 27–30 — though it has been arriving earlier in recent years due to climate pattern shifts.
With the Western Disturbance clearing and normal heat expected to rebuild from June 2–3, the pre-monsoon period (Nautapa plus heat weeks) will likely intensify before the Southwest Monsoon finally arrives. IMD’s current long-range forecast suggests a normal to above-normal monsoon for most of northwest India in 2026.
Delhi’s Hottest Stations — Where the Heat Was Worst
During the May 25–27 heatwave peak, here is how Delhi’s various weather stations compared:
| Station | Peak Max Temperature |
| Aya Nagar | 46.4°C |
| Ridge | 46.3°C |
| Narela | 45.3°C |
| Palam | 45.8°C |
| Safdarjung (Official) | ~44°C |
| Najafgarh | 45.1°C |
Safdarjung Observatory is Delhi’s official temperature marker — but suburban and outer Delhi stations regularly record 1–3°C higher due to reduced vegetation, more concrete and less tree cover.
