March is Tulum's driest month, with only about 33 mm of rain, average highs of 30°C, lows of 21°C and the sea at about 27°C. The first half is the better bet. Mexico's Easter school break runs from 22 March 2027 and Easter Sunday is 28 March, so the last third of the month is busy.
Tulum in March has the best weather on paper: it is the driest month of the year, with about 33 mm of rain in the official normals, average highs of 30°C, lows of 21°C and the sea at about 27°C. Sargassum season usually starts in April. Easter is the drawback: in 2027 Holy Week runs from 21 to 28 March and Mexico’s school break from 22 March to 2 April, so the first half of March is the time to come.

|---|---|
| Average high | 30°C |

Figures are CONAGUA’s 1991 to 2020 normals for the Tulum station, with sea temperature from WeatherSpark. WeatherSpark’s model also names March the driest month, at 34 mm, so the two sources agree here. It rates late November to mid-March the best stretch for general outdoor activity, which puts the first half of March at the end of that window. Nights are a couple of degrees warmer than in February. The hot season, with average highs above 32°C, starts around 13 April.
The first two weeks of March, before the long weekend, are the quietest. If you have to travel over Easter, book rooms and small-group tours early, and plan cenote visits for the 8:00 opening. The where to stay in Tulum guide covers each area.
The sargassum season usually runs from April to October, heaviest from June to August, so March is normally one of the last clear months for the beach. 2026 showed the season can start early: Tulum had collected 185 tonnes by late January. Check a tracker before you book a beach hotel, and see Tulum sargassum for what to watch.
March suits everything, so the order of the day matters more than the choice:

March sea temperatures of about 27°C make it a good month for the reef. In Akumal, rules reported in March 2026 require visitors to go with a certified guide, in groups of no more than six, and to spend only two to three minutes with each turtle. Off Tulum, boat snorkel trips visit Tulum’s reef, with a view of the ruins from the sea.
February has similar weather with no Easter crowds and a slightly cooler sea. January and December are cooler, with their own holiday peaks. From April the heat and the sargassum season both begin. The full table is in best time to visit Tulum.

Yes, it has the best weather on paper: the least rain of the year and sargassum season usually not yet started. Easter is the drawback: in 2027 Holy Week runs from 21 to 28 March and Mexico's school Easter break from 22 March to 2 April, so the end of the month is busy. Come in the first half for the weather without the crowds.
Easter Sunday is 28 March 2027, so Holy Week, Semana Santa, runs from Palm Sunday on 21 March. Mexico's 2026 to 2027 school calendar gives a break from 22 March to 2 April 2027, with one press report saying 3 April. If your trip overlaps, book rooms and any tours early.
Usually not much. The usual season runs from April to October, heaviest from June to August, so March is normally one of the last clear months.
