excerpt: "March is tricky — it's peak spring break for some spots, shoulder season gold for others. Here are the 6 beaches I'd actually book right now, with the real talk on crowds, costs, and whether the water's warm enough to swim."

Okay so March is that weird in-between month where half the beaches are swarming with spring breakers and the other half are basically perfect. I've been to pretty much every major beach destination in March at some point — sometimes intentionally, sometimes because I messed up the timing and learned the hard way.

Here's my honest ranking of where to go (and where to skip) this March, based on weather, crowds, and whether you're actually going to enjoy yourself.

🥇 1. Tulum, Mexico — But Only If You Do It Right

The water temp: 79°F (swimmable, but bring a light coverup for evening)
The crowd situation: Moderate to heavy — spring break is real here
The damage: $1,200-2,500 for a week (flights + hotel)

Okay so Tulum gets a lot of hate online and honestly? Some of it's fair. The beach road is dusty, the boutique hotels are overpriced, and the Instagram crowd can be a lot. But — and this is a big but — March is actually a sweet spot for Tulum itself. The sargassum seaweed season hasn't hit yet (that nightmare usually starts in May), the weather is that perfect 80°F with low humidity, and the cenotes nearby are at their best.

My move: Skip the overhyped beach hotels and stay in Tulum Pueblo (the town). You'll pay half the price, eat better tacos, and you can bike to the beach in 15 minutes. Or just day-trip to the beach from your cheaper, nicer Airbnb.

Skip if: You're on a tight budget. Tulum's "cheap backpacker" era is over. Go to Puerto Escondido instead (see below).

🥈 2. San Diego, California — The Sleeper Pick

The water temp: 62°F (lol, but hear me out)
The crowd situation: Surprisingly manageable
The damage: $800-1,500 for a week

I know, I know — 62°F water sounds like torture. But March in San Diego isn't really about swimming (unless you're in a wetsuit, which the surfers are). It's about 70°F sunny days, basically zero humidity, and those California beach vibes without the summer crowds.

Mission Beach and Pacific Beach are lively but not spring-break-crazy. La Jolla is stunning and the seals are out on the beach. And if you do want to swim, the Hotel Del Coronado has heated pools and that iconic red-roofed backdrop.

The real win: San Diego is cheaper in March than any other month, and you can actually get reservations at the good restaurants. Also — the wildflowers are blooming at Anza-Borrego if you want a break from the sand.

Skip if: You have your heart set on warm-water swimming. The Pacific is cold, full stop.

🥉 3. The Outer Banks, North Carolina — Shoulder Season Gold

The water temp: 55°F (hard pass on swimming)
The crowd situation: Ghost town (in the best way)
The damage: $600-1,000 for a week

You know I'm obsessed with the Outer Banks, and March is the month I tell everyone about who will listen. Is the water cold? Absolutely. But the beaches are YOURS. Like, literally empty. You can walk for miles and see maybe three other people.

This is the month for: Long walks on the beach, cozy rental houses with fireplaces, hot tub stargazing, and rates that are 40% of summer prices. The weather is 60-65°F during the day — sweatshirt weather, but sunny and gorgeous.

My favorite March move: Rent a house in Nags Head or Kill Devil Hills, bring a stack of books, and treat it like a beach retreat rather than a beach vacation. The fishing is incredible this time of year too if you're into that.

Skip if: You need warm water or lively nightlife. March OBX is for resetting, not partying.

4. Puerto Rico — Caribbean Without the Passport Hassle

The water temp: 79°F (perfection)
The crowd situation: Moderate — spring break light
The damage: $900-1,800 for a week

Puerto Rico in March is basically perfect. The rainy season is over, the humidity hasn't kicked in yet, and the water is that ideal "jump right in" temperature. Plus — no passport needed for US travelers, which is clutch for last-minute bookers.

San Juan is great for the classic Old San Juan + beach combo, but honestly? I send people to Rincón on the west coast. It's surfier, chiller, and the sunsets are the best in the Caribbean (I will fight anyone on this). Or Vieques if you want that bioluminescent bay experience — March is prime time for the glow.

The deal alert I saw: Flights from the East Coast are running $198-250 roundtrip right now, which is genuinely excellent for Caribbean access.

Skip if: You're looking for all-inclusive resort vibes. PR doesn't really do that — it's more independent travel, which I personally prefer.

5. Kauai, Hawaii — If You're Going to Splurge

The water temp: 76°F (perfect)
The crowd situation: Busy but not insane
The damage: $2,000-3,500 for a week

Everyone defaults to Maui, but Kauai in March? Chef's kiss. The winter surf is still pumping on the north shore (watch the pros at Hanalei Bay), the weather on the south shore is dry and perfect, and the island just feels less... developed than the others.

Poipu Beach on the south shore is your safest bet for calm swimming and sunny weather. Hanalei Bay is gorgeous but the water can be rough in winter — great for watching surfers, not for casual swimming.

March reality check: This is whale season, so you might spot humpbacks from the shore. That's worth the price of admission alone.

Skip if: You're on a budget. Hawaii is never cheap, but March is peak season pricing. Save this for a splurge trip.

6. Puerto Escondido, Mexico — The Anti-Tulum

The water temp: 81°F (bathtub warm)
The crowd situation: Chill, mostly surfers and locals
The damage: $700-1,200 for a week

I mentioned this as the Tulum alternative, and I meant it. Puerto Escondido is what Tulum was 15 years ago — authentic Mexican beach town, incredible food, warm people, and prices that haven't gone insane yet.

Zicatela Beach is the famous surf break ( Pipeline of Mexico), but Carrizalillo is the swimming beach you actually want — calm cove, clear water, $2 fish tacos from the beach vendors. The whole town has this laid-back, surfy energy that's just... real.

The catch: It's harder to get to. You fly into Oaxaca or Mexico City and take a small plane or a 6-hour bus. But honestly? That's why it's still authentic.

Skip if: You need luxury resorts or easy logistics. This is for travelers, not tourists.

🚫 The "Maybe Skip This Month" List

Cancun Hotel Zone: March is peak spring break chaos. Unless you're 22 and want to party, avoid.

Miami Beach: Same deal. South Beach in March is a scene, and not a relaxing one.

Myrtle Beach: Still cold, not warm enough to swim, and the boardwalk stuff isn't open yet. Wait for April.

Anywhere in Thailand: March is hot. Like, dangerously hot (95°F+ with brutal humidity). Wait for November-February.

If I'm booking today: Outer Banks for a cozy reset, or Puerto Escondido if I want warm water and tacos.
