We score 50+ destinations on 6 criteria — sunshine, water clarity, seaweed-free rating, rain risk, storm risk, and swimmability — to find the world's best beach every month.
Based on CheckBeachConditions scoring across tracked destinations. Rankings reflect typical May conditions weighted against live daily data — not a guarantee of conditions on any specific day.
Baby Beach sits at the southeastern tip of Aruba, tucked inside a protected natural lagoon that makes it unlike virtually any other beach in the Caribbean. The water is knee-deep for most of the bay, crystal-clear, and almost completely flat — no surf, no chop, no rip currents. For swimming conditions alone, it's nearly unbeatable.
What elevates it for May is Aruba's structural advantage: the island sits 15 miles off the Venezuelan coast, well outside the main sargassum drift belt. While other Caribbean islands start seeing sargassum build in May, Baby Beach sees virtually none. Combined with Aruba's near-zero rainfall (just 18 inches per year — the driest island in the Caribbean) and 330+ sunny days annually, it scores near-perfect on sunshine, seaweed risk, and rain risk simultaneously.
The Atlantic hurricane season officially begins June 1, so travelers in May sidestep that concern entirely. Water temperatures hold around 82°F. It's not the flashiest beach, but in May it is the most reliably perfect one in the scoring model.
Anguilla consistently earns its place near the top of Caribbean rankings, and May is one of its best months. Shoal Bay East's ultra-low sargassum levels — a structural feature of Anguilla's northern position — combined with world-class water clarity (it ranks #6 in North America on the World's 50 Best Beaches list) make it an exceptional scoring destination.
In May, Anguilla's dry season hasn't fully ended, so sunshine scores remain high and rain risk is minimal. It edges out other top competitors on water clarity, which carries real weight in our model.
May is one of the most underrated months for international beach travel. Here is what each region offers:
May falls just before the unofficial start of sargassum peak season and the hurricane season (June 1). Most destinations have manageable seaweed levels, warm water (82–86°F), and thinner crowds than the winter high season. Best picks: Turks & Caicos, Aruba, Exuma, Anguilla, Bonaire.
May is excellent in Hawaii. Waikiki and Maui enjoy low surf, warm water (~79°F), and minimal jellyfish risk. No sargassum anywhere in Hawaii makes it a reliable clarity pick. Summer crowds haven't arrived yet, so beaches feel uncrowded compared to June–August.
May is warming up fast — Santorini and Mykonos water temperatures reach 68–72°F. Not warm enough for extended swimming for everyone, but the weather and scenery are exceptional. Beach crowds are still manageable before the June–August peak. Best for atmosphere over swimming.
May is tricky for Southeast Asia. Thailand (Phuket, Koh Samui), Bali, and the Philippines enter monsoon or pre-monsoon season. The Maldives shifts into its southwest monsoon — conditions deteriorate quickly after mid-May. If you are set on Southeast Asia in May, Bohol (Philippines) is one of the safer picks before typhoon season strengthens.
Florida in May means warm Gulf water (78–82°F), low sargassum, and less crowded beaches than peak spring break. Destin, Clearwater, and Siesta Key offer excellent conditions. East coast destinations like South Beach and Fort Lauderdale can see moderate seaweed in May but are still pleasant.
Our monthly winner is determined by a 6-criteria weighted scoring model. Each destination receives a score from 0–100 on every criterion, with higher always meaning better beach conditions.
The destination with the highest composite weighted score — provided it has a green (beach-ready) verdict on our live conditions tracker — is named the monthly winner. Scores are recalculated daily using live sensor data and AI-powered assessment.
