Weather in Alappuzha in March

Shoulder season. March is shoulder season in Alappuzha — cheaper, quieter, and a genuine gamble. Highs average 31.6 °C, lows 27.7 °C, and rain falls on 10 days — nothing in the month is working against you.

March ranks 4 of 12 in Alappuzha: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 10 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.6 °C days and 27.7 °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: 29 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest March day reached 34.6 °C and the coldest night fell to 25.4 °C, and the wettest single day dropped 69 mm — roughly 103% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 1 mm to 320 mm across the twenty years measured — a 319 mm spread around an average of 67 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 10.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.

How March sits in the year

Temperatures hold steady either side: 31.1 °C in February, 31.6 here, 30.8 in April. Nothing about the timing within the month matters much. Rain is the thing that moves: April brings 9 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in March

Alappuzha sits close enough to the equator that daylight barely moves all year — 12.1 hours in March, against a range of just 1.1 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.5 °C in March — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

March in Alappuzha versus nearby

If Alappuzha is one option among several, the nearby comparison is worth making. Munnar is a better bet in March — 3.6 °C cooler, 2 days less rain. Teni is the weaker option in March — 4.7 °C warmer, 4 days less rain.

So: March is a compromise. January is 21 points better and is what Alappuzha is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
