The Caribbean has two seasons and only two: dry, from December to April, and wet, from June to November — the second overlapping almost exactly with the Atlantic hurricane season, which officially opens on 1 June and closes on 30 November. Everything about timing a trip here follows from those dates: prices, crowds, sea conditions, whether your travel insurance is worth anything, and in the worst case whether your resort is still standing when you land.
The good news is that the risk is far from evenly spread. It is concentrated in a nine-week window, it varies enormously between islands, and three of the most developed destinations in the region sit outside the belt altogether. Below is the year broken down as a traveller actually experiences it.
December to April — peak season
This is why the Caribbean has a reputation for perfect weather. Daytime temperatures settle at 25-28°C, nights at 20-22°C, humidity holds around 65-75 per cent, and the trade winds blow steadily at 10-20 knots — enough to keep the air moving without ruining the beach. Rainfall drops to 50-100 mm a month, most of it in brief afternoon showers. The sea flattens out, which matters more than most people expect: this is the only stretch of the year when sailing, diving and snorkelling are reliably good across the whole region rather than only on sheltered leeward coasts.
Hurricane risk in these months is effectively zero. No major hurricane has ever formed in the Atlantic basin in February or March.
The price is the price. Expect to pay 30 to 100 per cent more than in the off-season, and to book months ahead for anything over Christmas, New Year and Easter — those three windows are the most expensive weeks of the Caribbean year, and on the smaller islands, where the hotel stock is measured in dozens of rooms rather than thousands, they sell out by autumn.
May and November — the shoulder months
If you want one recommendation from this article, it is these two months. The weather is still warm and mostly dry, statistical probability of a major storm is under five per cent, prices fall 20-40 per cent from peak, and the beaches, restaurants and dive boats are noticeably emptier.
November carries a little residual risk from late-season Atlantic storms, but by then most systems track north of the Caribbean towards Bermuda and the eastern United States. Late November — after the season formally closes on the 30th but while northern-hemisphere winter crowds have not yet arrived — is arguably the single best value fortnight of the year.
June to August — early hurricane season, and workable
Counter-intuitively, July is statistically the quietest month of the official hurricane season. The Atlantic needs time to warm up, and early-season systems tend to be weaker and to form further west, in the Gulf.
What you get in exchange: sea water at its warmest, 28-30°C, which is bathwater for swimming and pleasant for long dives; prices 40-60 per cent below peak; and short, heavy afternoon downpours that clear as fast as they arrive. What you risk: sargassum. The floating seaweed drifts in on Atlantic-facing shores from roughly May onwards and can pile up knee-deep on east coasts, while the Caribbean-facing side of the same island stays clear. If you are travelling in these months, check which coast your hotel is on — it is the difference between a clean beach and a smell of rotting weed.
Safer bets for this window: the Caribbean coast of Mexico around Cancun and the Riviera Maya, and Aruba, Bonaire and Curacao, which lie outside the belt.
September and October — peak risk
Around 85 per cent of major Atlantic hurricanes form between mid-August and mid-October, with the climatological peak on 10 September. The Lesser Antilles and the northern Greater Antilles are the most exposed, being the first land the systems meet as they cross from Africa.
Prices bottom out, and some hotels close entirely for maintenance. If you travel now, treat cancellation as a live possibility rather than a formality — and understand that the disruption is rarely a direct hit. It is a closed airport for two days, a cancelled ferry, a dive operation grounded by swell.
Practical hurricane preparation
- Travel insurance with explicit named-storm cover is essential between 1 June and 30 November. Many standard policies exclude weather events, or only pay out once an evacuation order has been issued.
- Most larger resorts offer free rebooking if a cyclone is forecast within 48-72 hours of your arrival. Get that promise in writing before you pay.
- Follow the NOAA National Hurricane Center rather than news headlines. It publishes forecast cones every six hours during an active system, and a cone is a probability, not a path.
- Pack light rain gear from May to November even for a fortnight the forecast calls dry.
- Storms are tracked days in advance. Nobody in the Caribbean is surprised by a hurricane — the risk to a traveller is lost days and grounded flights, not personal danger, provided you follow local instructions.
Island by island — when to go
- Aruba, Bonaire, Curacao — year-round. These three sit at roughly 12°N off the Venezuelan coast, south of the belt, and have not taken a direct major hurricane in living memory. The trade-off is a dry, cactus-and-scrub landscape rather than rainforest.
- Trinidad and Tobago — year-round, for the same latitude reason. Carnival, in February, is the peak of the calendar and priced accordingly.
- Barbados — December to July is safe; August to November carries occasional risk. Its position at the eastern edge of the arc means systems often pass just north.
- Lesser Antilles, from Anguilla down to Grenada — December to June is the window. Grenada, in the far south, is statistically safer than the northern islands of the chain.
- Bahamas — December to May is ideal. This is the most hurricane-exposed archipelago in the region and also the coolest in winter: January nights can drop to 17°C.
- Cuba — December to April is dry; May to October brings both rain and cyclones. The dry season is also the best time for Havana, where summer humidity in the old city is punishing.
- Cayman Islands — December to May, with less exposure than the Bahamas but not none.
- Jamaica, Dominican Republic, Puerto Rico — December to April. All three have mountainous interiors that stay green year-round and sheltered south coasts that fare better in the wet months.
Weddings and honeymoons
Two windows work best: late November, once the season has closed but before the December price jump, and early May, before the rains build. Both give you near-guaranteed sunshine, smaller crowds and rates well below Christmas. Note that many islands require documents to be lodged with the local registry a set number of days before the ceremony — from 24 hours in the Cayman Islands to several days elsewhere — so build that into the arrival date.
The short version
For certainty, go between December and April and pay for it. For value with barely any added risk, go in May or late November. For the lowest prices, go in September or October, buy proper insurance, and pick an island outside the belt. And if the dates are fixed and cannot move, Aruba, Bonaire, Curacao and Trinidad remove the question entirely.
