Weather in Guwahati in January

Prime time. If you get to pick your dates, January is the one. Highs average 24.4 °C, lows 11.5 °C, and rain falls on 1 days — nothing in the month is working against you.

January is the highest-scoring month of the twelve. The nearest rival is December, and the month at the other end of the year is August.

Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average January reaches 30 °C. Across the twenty years measured, the hottest January day reached 30.5 °C and the coldest night fell to 5 °C.

January is dependably dry, and that reliability is the point: across the twenty years measured, the wettest January on record still only managed 35 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Januarys brought 20 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

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 76%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 25.2 °C in December, 24.4 here, 27.7 in February. Nothing about the timing within the month matters much.

Daylight in January

January sits at the dark end of Guwahati's year — 10.7 hours of daylight against 13.8 at midsummer, gaining 0.4 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

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

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

January in Guwahati versus nearby

If Guwahati is one option among several, the nearby comparison is worth making. Dārjiling is the weaker option in January — 11.9 °C cooler, the same number of rain days. Kolkata is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: January is the answer for Guwahati. If it is booked out or priced out, December is the next best thing at 0 points behind, and August is the month to keep off the shortlist.
