Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Hotel rates drop 25-35% from winter peak - luxury resorts that require three-month advance bookings in February suddenly have availability with two weeks notice
- + Sea conditions calm between storm systems - the channel between St Lucia and Grenada flattens out, making inter-island ferry rides bearable instead of vomit-inducing
- + Mango season hits full stride - roadside stands from Castries to Vieux Fort sell bags of Julie and Francis mangos for a fraction of grocery prices back home
- + Turtle nesting season begins - Anse Chastanet and Grande Anse beaches host guided night walks to watch leatherbacks haul themselves ashore under moonlight
Considerations
- − Afternoon thunderstorms roll in like clockwork around 2:30pm, turning every outdoor activity into a timed event - hiking Gros Piton requires a 6am start or you're climbing in a waterfall
- − The humidity jumps to 70% and stays there - your camera lens fogs every time you step outside, and clothes never fully dry between the shower and the closet
- − Some restaurants close for 'low season renovations' - the beachside spots in Rodney Bay tend to shutter for three-week kitchen overhauls
Best Activities in May
Top things to do during your visit
Gros Piton Sunrise Hikes
May's morning temperatures at 26°C (79°F) make the 600m (1,970 ft) climb manageable before afternoon storms build. The trail dries out overnight but hasn't turned to dust yet - you'll get actual grip on the volcanic rock instead of sliding on loose gravel like in drier months. Start by 5:30am to reach the summit before clouds obscure the view of Petit Piton and the Caribbean stretching to Martinique.
Booking Tip: Book licensed guides through the visitor center in Fond Gens Libre - they require 48 hours notice in May versus two weeks in peak season. Current tour options appear in the booking widget below.
Mangrove Kayaking Tours
The calm morning waters of Marigot Bay in May let you paddle through red mangrove tunnels without fighting trade winds that pick up in winter. Guides point out juvenile barracuda and starfish in water clear enough to see 3m (10 ft) down - visibility that disappears when rain churns up sediment later in the day.
Booking Tip: Morning sessions run 7am-10am to avoid both storms and the midday heat. See current operators in the booking section below.
Friday Night Fish Fry in Anse La Raye
May's lower tourist numbers mean the fish fry feels like a village party rather than a cruise ship excursion. Local families set up tables along the waterfront road selling mahi-mahi, snapper, and lobster grilled over coconut husk fires - the smoke mixing with sea salt in air that finally cools to 24°C (75°F) after sunset.
Booking Tip: No reservations needed - just show up at 7pm when the church bell rings and follow your nose. Current transport options from your hotel appear below.
Soufrière Sulphur Springs Mud Baths
Afternoon storms improve the hot springs experience - the rain cools the air temperature so the 38°C (100°F) mud baths feel therapeutic instead of oppressive. The mineral smell of sulphur mixes with petrichor from incoming weather, creating that distinctive 'Caribbean spa' scent you'll remember years later.
Booking Tip: Visit between 2-4pm when cruise crowds have departed but before storms arrive. Check current availability in the booking widget.
Pigeon Island Snorkeling
The island's leeward side stays flat even when afternoon squalls kick up - you can snorkel among parrotfish and trumpetfish in water that stays 28°C (82°F) year-round. May's lower visitor numbers mean you'll share the beach with maybe six other people instead of sixty.
Booking Tip: Bring your own gear - the on-site rental shack closes sporadically for 'maintenance' in low season. Current snorkeling tour options appear below.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The hourly water taxi from Rodney Bay to Pigeon Island runs even in light rain - captains keep going until lightning appears, giving you a private island experience when cruise passengers cancel
Local buses painted with 'D' on the windshield follow coastal routes for a fraction of tour bus prices - they leave when full, not on schedule, so bring patience and small bills
Skip the market itself. Walk 200m past Castries toward Choc and look for Miss Juliet's stall. She grows only Julie mangoes. Ask in Creole: "Ka ouvè on ti pwason." She'll slice one on the spot. Juice runs down your wrist. Best mango on the island.
Gros Islet wakes up every Friday. Street party starts early. Fishermen haul boats up before 6pm. They clean mahi-mahi right there. Ask nicely; they'll hand you a fillet. Take it to your hotel kitchen. Grill it simply. You'll taste the sea.
Avoid These Mistakes
Book morning slots only. May's storms roll in between 2-4pm like clockwork. Afternoon excursions get washed out. Guides know this. They still sell them. Don't bite. Sunrise departures guarantee blue sky.
Rainy season does not mean all-day soakers. Showers crash down, then vanish. Tourists hide inside for nothing. Plan outdoor mornings. Carry a light shell. Dry by lunch.
Denim is a trap. Ten minutes outside and jeans turn into a wet towel. Humidity sticks at eighty percent. Pack linen or rayon. Your skin will thank you.
