How to choose your March sun trip
Dodge the spring-break spike
Every destination on this list gets hit by the mid-March school-break wave - fares and beachfront rates can jump 50% for those two weeks. The first week of March and the last few days buy identical weather at real discounts. If mid-March is fixed, book flights the moment dates are known.
Swimmable sea vs. poolside warmth
If ocean swimming is the point, the Caribbean and Mexican picks are the safe bets - 26°C water everywhere. Palm Springs trades the sea for guaranteed cloudless warmth and pool culture; south Florida sits between, with the Keys' water at 25°C and the Atlantic beaches a touch cooler.
Passport math changes the value equation
For US travelers, Key West, Miami, Palm Springs, San Juan and Hawaii skip customs entirely - worth real money and hours with kids in tow. International picks reward the paperwork with lower on-the-ground prices: Punta Cana and Cancun deliver the cheapest warm-water week on the list.
March is the last easy month for the Caribbean
Hurricane season starts in June and insurance pricing knows it. March bookings carry none of that calculus - it's peak dry season across the entire basin, which is exactly why it's peak price season too. For the same trip 30% cheaper with modest extra risk, May is the arbitrage month.
