The seasonal pattern for Guadeloupe — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.
Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.
The dry season, roughly January to April, is the sweet spot: the year's most comfortable air and, for snorkeling, the cleanest water on Basse-Terre's west coast, because visibility there depends on what washes off the rainforest volcano — the dry months run clear, with water around 27–28°C and a rash guard plenty. December and early January bring those same conditions with holiday crowds and prices. Roughly May to June is the shoulder: warmer, quieter, occasional showers and still good snorkeling before the rains settle in. From roughly June to November it is the wet and hurricane season — the season peaks around 10 September and even a non-hurricane system can kill a week — with peak coral heat stress and the murkiest water landing roughly late October to mid-November, so a snorkel-first trip belongs in the dry half of the year.

Guadeloupe is the French Caribbean’s snorkeling crown jewel: the Réserve Cousteau, the marine reserve Jacques Cousteau himself championed and filmed in, sits in gin-clear water off Basse-Terre’s volcanic west coast — green turtles grazing the shallows, tarpon patrolling the drop-offs, and Cousteau’s own statue resting on the seabed. It is Europe in the tropics (euros, French hospitals, EU standards) wrapped around genuinely world-class Caribbean reefs, plus the satellite islands — Petite-Terre and Les Saintes — that most visitors never reach. Go in the dry season: the cleanest west-coast water runs roughly January to April, and June to November is hurricane season.
