March is a strategic month. The Caribbean is still in its driest stretch, the rains haven't started in Sri Lanka, and Mexico's Riviera Maya is at its most pleasant before the spring break wave. Vietnam's central coast around Da Nang and Hoi An opens up after the winter monsoon, with calm seas returning along My Khe and An Bang. The Maldives keeps doing what it does, but March is statistically the sunniest month of the year there.
Why March works
Caribbean temperatures sit at 28 to 30 C. The Riviera Maya runs 28 C and dry. Sri Lanka's south coast around Mirissa and Weligama stays 30 C with sea breeze. Vietnam's central coast warms up to 28 C with the Cham Islands sea calming down enough for day trips. Maldivian sunshine peaks at around 10 hours per day this month.
Punta Cana and the Dominican north coast around Las Terrenas have warm, calm Atlantic water at this point in the year. The Caribbean side of the Riviera Maya, especially Tulum, Akumal, and Soliman Bay, is reef-protected and ideal for snorkeling. Sri Lankan south coast has small surf at Weligama and a calmer swim at Mirissa cove. The cenotes inland from Tulum stay a refreshing 24 C all year and balance hot beach afternoons.
The five destinations we keep returning to
Riviera Maya, Mexico
Tulum south, Akumal turtles, Bacalar lagoon further south. Daytime temperatures average around 28 C / 82 F. The water sits warm enough that the first swim of the morning feels like an unhurried decision rather than a brave one. Locals fall into a daily rhythm around the sun: early walk, late breakfast, long swim, slower lunch, quiet hour, second swim, sunset somewhere with a view.
The reason Riviera Maya works in March comes down to geography. The prevailing wind pattern keeps humidity in check, the sea has had enough time to either warm up or stay warm, and the local tourism rhythm is either at its considered peak or in a friendly shoulder. Either way, restaurants are open, transport is running, and accommodation has enough choice that you do not need to compromise.
Dominican Republic, Caribbean
Las Terrenas on Samana, Bayahibe for diving, Cabarete for wind sports. Daytime temperatures average around 29 C / 84 F. The water sits warm enough that the first swim of the morning feels like an unhurried decision rather than a brave one. Locals fall into a daily rhythm around the sun: early walk, late breakfast, long swim, slower lunch, quiet hour, second swim, sunset somewhere with a view.

Sri Lanka, South Asia
Mirissa, Tangalle, Hiriketiya. Late March is the last clean window. Daytime temperatures average around 30 C / 86 F. The water sits warm enough that the first swim of the morning feels like an unhurried decision rather than a brave one.

How to plan it
- Avoid spring break weeks in the Riviera Maya unless you actively want the energy. Mid-March to early April is peak.
- Sri Lanka's south coast surf school season ends around early April. Book lessons in the first half of the month.
- Vietnam's Hoi An is best as a base. Da Nang for beach, Hoi An for old town, then back to the sand.
- Dominican Republic resorts vary wildly. Read recent reviews. The country is huge and one-coast advice doesn't transfer.
Where to stay
Tulum has shifted upmarket but the beach road still works if you book early. Akumal and Soliman Bay are quieter alternatives with the same warm water. Las Terrenas on Samana has French and Italian-run small hotels that beat the big chains for atmosphere. Sri Lankan boutique villas around Talalla and Dickwella are at the right price-to-quality ratio. Vietnam's An Bang Beach has a strip of family-owned homestays at half the cost of Da Nang's resorts.
Final thoughts
March is a planner's month. The weather windows are clean if you pick the right coast on the right week.
If you take only one piece of advice from this guide, take this. The best March trip is not the one that ticks the most destinations, it is the one that gives the sun and the water enough time to do what they are good at. Stay longer in fewer places. Eat where the menu is short. Walk barefoot when you can. The chase for summer is rarely about distance, it is about timing, and March is one of those months that pays the patient traveler back in full.
