People ask me every week on WhatsApp: “When is the best season in Guadeloupe for nature?” My answer as a local always frustrates them a little: it depends on what you’re coming for. The best Guadeloupe nature season isn’t the same for climbing La Soufrière in dry conditions, seeing the Carbet Falls at full power, or diving the Cousteau Reserve with 30 metres of visibility. The butterfly-shaped archipelago lives to the rhythm of two seasons — the dry season (December to April) and the rainy season (June to November) — and each has its golden windows. Here’s the calendar I give our travellers, month by month.
Understanding Guadeloupe’s dry season: the prime hiking season
Guadeloupe’s dry season runs from December to April. The trade winds blow steadily, humidity drops, and the trails of Basse-Terre — often muddy the rest of the year — become walkable without wading.
Why the dry season changes everything on the trails
- La Soufrière (1,467 m): between January and April, your odds of a cloud-free summit climb sharply. Count on 2.5 to 3.5 hours round trip from Bains Jaunes, setting off before 7 a.m. — after 10 a.m., the “old volcano” almost always pulls on its cap of cloud.
- The Trace des Crêtes or Morne Léger: dry ground, less slippery root-laced sections, and open panoramas over the Côte-sous-le-Vent.
- Temperatures: 24 to 29 °C on the lowlands, around 15 °C at La Soufrière’s summit at daybreak. Bring a fleece — people thank me for that tip every time.
The flip side: this is high season. Paris–Pointe-à-Pitre flights (Pôle Caraïbes airport) climb to €800–1,100 round trip between mid-December and early March, versus €450–600 in June or October. If you’re aiming for February, book your accommodation in Guadeloupe four to six months ahead.
Beaches and the dry season: the obvious combo
From December to April, the sea is generally calm on the Caribbean side and Grande-Terre’s beaches — La Caravelle in Sainte-Anne, the Saint-François lagoon — offer their turquoise waters almost free of sargassum. Grande Anse in Deshaies, my favourite at sunset, sometimes sees a northerly swell between December and February: watch the flags, the shore break is serious on those days.
Rainy season: the secret of full-flowing waterfalls
Here’s the counterintuitive tip I keep repeating: if you’re coming for the waterfalls, the rainy season is your ally. From July to November, the rains swell Basse-Terre’s rivers and turn trickles into spectacular curtains.
- Carbet Falls: the second fall (110 m), reachable in a 45-minute walk on a developed path (site entry: around €2.50 per adult), is twice as impressive in September as in March.
- Cascade aux Écrevisses: a 10-minute walk from the car park on the Route de la Traversée, perfect even with children, but avoid swimming after a heavy downpour — flash floods are real.
- Saut de la Lézarde, the pools of Vieux-Habitants: full, green and photogenic.
The golden rule of the rainy season: set off early (showers concentrate in the afternoon), check the Météo-France alerts every morning, and never cross a river that has turned cloudy. The National Park’s forest is then an almost unreal green, with ten times fewer people than in February.
Diving and snorkelling: the windows to know
The Cousteau Reserve, off Malendure beach in Bouillante, can be dived year-round thanks to the Côte-sous-le-Vent being sheltered from the trade winds. But not all periods are equal.
- April to June: my favourite window. Glassy sea, 20 to 30 m visibility around the Pigeon islets, water at 27–28 °C, and the clubs are less crowded than in high season. Discovery dive around €60–70, exploration dive €45–55, a 2-dive package often €90.
- December to March: excellent conditions too, but book your club 3–4 days ahead; this is peak crowds. Huge bonus: it’s humpback whale season (January–April), sometimes heard while diving and observable on a dedicated outing (€55–70 for a half day).
- September–October: warmest water (29 °C), but variable visibility after the rains and a risk of cancellation if a tropical wave moves through.
For free snorkelling, the transparent kayaks departing from Malendure (€25–35 for 2 hours) remain a safe bet. And don’t skip Petite-Terre: the reserve, reachable by catamaran from Saint-François (a full-day excursion around €95–120), teems with turtles — outings run year-round but are cancelled in strong easterly swell.
