Weather in Guwahati in July

The month to avoid. Of the twelve, July is the one to avoid. You should expect rain on 29 days of the month, which is more days wet than dry.

July ranks 11 of 12 — near the bottom of Guwahati's year. January is the month that works, and the swing between the two is 69 points, which is a different holiday rather than a slightly better one.

Rain on 29 of the month's 31 days, 13 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 13 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest July day reached 39 °C and the coldest night fell to 24.3 °C, and the wettest single day dropped 101 mm — roughly 28% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 575 mm against 176 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 364 mm average is a reasonable planning figure, not a promise.

Wind is light at 1.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 34.9 °C in June, 34.5 here, 34.3 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Guwahati's year: 13.6 hours of daylight, losing 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 23.4 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Guwahati versus nearby

If Guwahati is one option among several, the nearby comparison is worth making. Dārjiling is a better bet in July — 14.3 °C cooler, 1 day more rain. Kolkata is a better bet in July — 2.9 °C cooler, 1 day less rain.

So: July is a compromise. January is 69 points better and is what Guwahati is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
