Weather in Guwahati in March

Shoulder season. March is shoulder season in Guwahati — cheaper, quieter, and a genuine gamble. Highs average 31.9 °C, lows 17.5 °C, and rain falls on 8 days — nothing in the month is working against you.

March ranks 5 of 12 in Guwahati: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 8 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.9 °C days and 17.5 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 25 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest March day reached 37.4 °C and the coldest night fell to 10 °C, and the wettest single day dropped 42 mm — roughly 71% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 14 mm to 156 mm across the twenty years measured — a 142 mm spread around an average of 59 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 2.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 61%.

How March sits in the year

The month is on the way up: 4.2 °C warmer than February, and April adds another 2.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain is the thing that moves: April brings 12 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in March

12 hours of daylight, gaining 0.8 hours across the month. That is between Guwahati's extremes of 13.8 and 10.5 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23.4 °C between the year's warmest afternoons and coldest nights. Within March itself the daily swing is 14.4 °C, so mornings and afternoons need different clothes.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

March in Guwahati versus nearby

If Guwahati is one option among several, the nearby comparison is worth making. Dārjiling is a better bet in March — 12.5 °C cooler, 2 days less rain. Kolkata is the weaker option in March — 3.5 °C warmer, 3 days less rain.

So: March is a compromise. January is 36 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.
