As winter fades in the northern hemisphere, March in St Barts delivers Caribbean perfection. The island enjoys the final stretch of the dry season with reliable sunshine, comfortable humidity, and a lively atmosphere fueled by world-class events. Here's what March has in store.
March at a glance
Average temperature: 26-29°C (79-84°F) · Rain days: 5-7 · Sea temperature: 26°C (79°F)
Temperature and Sunshine
March temperatures range from 26-29°C (79-84°F) during the day, with pleasant nights around 23-25°C (73-77°F). You can count on 8-9 hours of sunshine daily, making it ideal for beach hopping and outdoor exploration.
Humidity remains comfortable at 70-75%, and the steady trade winds provide natural cooling throughout the day. Many visitors consider March to offer the island's most balanced weather.
Why March Stands Out
March marks the tail end of the dry season, with only 50-70mm of rainfall spread across 5-7 days. Showers are brief and rarely disrupt your plans—often just a quick afternoon sprinkle followed by clear skies.
Beach Conditions in March
The northeast trade winds blow at a steady 15-20 km/h, creating excellent conditions across most beaches. Western and southern shores remain calm and perfect for swimming.
What to Pack for March
March's sunny conditions call for classic warm-weather essentials:
- Light, breathable fabrics — Linen and cotton are perfect for the climate
- Reef-safe sunscreen — The tropical sun remains intense
- A light layer — Evenings can feel cool with the ocean breeze
- Water shoes — Useful for rocky beach entries and snorkeling
Booking tip
March remains high season, especially during the Bucket Regatta week. Book accommodations 2-3 months ahead for peak dates.
March Events
The highlight of March is the St Barths Bucket Regatta, typically held mid-month. This prestigious superyacht race transforms Gustavia harbor into a showcase of the world's most impressive sailing vessels. Even if you're not a sailor, watching these magnificent yachts compete is unforgettable.
