September and October are the months Grenada empties out. Carnival is over, schoolchildren are back in class, cruise calls are few, and some hotels and restaurants shut their doors for a few weeks of repairs and staff holidays. Room rates are at their lowest of the year, and the beaches look the way travel brochures promise: long stretches of sand with almost nobody on them.
The reason is the weather. These are typically among the wettest and most humid months, and they sit inside the peak of the Atlantic hurricane season. For some travellers that trade is not worth making; for others it is the best deal in the Caribbean. This guide sets out what the two months are actually like, so you can decide which group you belong to.
What the weather is really like
Expect heat and humidity rather than cool, grey days. Daytime temperatures are close to their annual high, typically around 30–32°C on the coast, and with the trade winds lighter than in winter, afternoons feel heavy. Nights are warm, so air conditioning or at least a good fan matters more now than in February.
Rain tends to arrive as heavy showers or thunderstorms, frequently building in the afternoon or overnight, sometimes as a morning of steady rain when a tropical wave passes. Many days still have several hours of sunshine. The difference between coast and interior is large: the south-west around Grand Anse and Point Salines is among the driest parts of the island, while Grand Etang and the central mountains receive far more rain, so trails and waterfalls are muddier and rivers can rise quickly.
The sea on the Caribbean side is often calm and clear when the wind drops, which is good news for snorkellers and divers. Rough patches come with passing systems and usually last a day or two.
Two other features of the season are worth knowing. Saharan dust, carried across the Atlantic on the easterly winds, can give the sky a milky haze on some days from early summer into autumn, which affects views and photographs more than anything else. And the Atlantic beaches on the east coast, such as Bathway and La Sagesse, can collect sargassum seaweed in some years, while the sheltered Caribbean-side beaches of the south-west are usually much less affected.
What you gain
The year's lowest room rates. Outside carnival week, summer and autumn rates are well below winter peaks, and September and October usually sit at the bottom of the curve. Resorts often add extras such as free nights, upgrades or dining credit.
Space everywhere. Grand Anse on a weekday can feel private, waterfalls have no queues and tables at popular restaurants are easy to get without a reservation.
Unhurried service. Guides, boat skippers and taxi drivers have more time and can be more flexible about timings and routes.
Good conditions underwater. Water temperatures are at their warmest, and calm days on the west coast can give excellent visibility for the Underwater Sculpture Park at Moliniere Bay and the reefs and wrecks off the south-west.
A green, full-flowing island. Rivers run strongly, the forest is at its most lush and the hillsides are vividly green.
What you give up
Certainty. This is the statistical peak of the hurricane season. Most weeks pass without a named storm, but when one threatens, flights are cancelled, the airport closes and the final days of a trip can be lost.
Some businesses. A number of hotels, restaurants and smaller tour operators close for part of September or October. Ask before booking, and check that the places you most want to visit are open during your dates.
Comfortable hiking. Mud, slippery rocks and higher rivers make longer walks such as Seven Sisters, Mount Qua Qua or Mount St Catherine harder and, after heavy rain, unwise.
Atmosphere. Without visitors, some beach bars and resort areas are quiet at night. If you want a buzz, the low season can feel flat.
Public holiday closures. National Heroes' Day on 19 October and Thanksgiving Day on 25 October are public holidays marked by ceremonies; offices, banks and many shops close.
Before you book: a low-season checklist
A few minutes of checking turns a gamble into a calculated choice:
- Confirm your hotel will be fully open, including restaurants, pools and spa, and ask whether any refurbishment work is planned during your stay.
- Buy travel insurance at the time of booking, and confirm it covers named storms, cancellations and extra nights.
- Choose flexible flights and rates if the price difference is modest.
- Plan the trip with a lighter, adjustable schedule: book boat trips and tours for the early part of the stay so they can be moved if the weather turns.
- Ask dive and boat operators which days they run in the quiet season, as some reduce their schedules.
- Bring a light rain jacket, quick-drying clothes and insect repellent; mosquitoes are more active after rain.
- Keep the last night on the main island near Maurice Bishop International Airport rather than on Carriacou.
Who the low season suits
September and October work best for travellers who value price and space over guaranteed weather and who can adapt. Divers and snorkellers do well, as do couples who plan to spend much of the time at a good hotel and want a calm, private feel. Remote workers on a longer stay, who can shift plans day by day, are well placed too. Repeat visitors who already know the island often enjoy seeing it without the crowds.
The months suit less well for first-time visitors with only a week and a long list of sights, hikers planning serious mountain walks, families tied to fixed school holidays, and anyone who would find a storm forecast stressful. For those travellers, late November or May gives much of the same value with less risk.
September and October compared with June and November
Price. September and October usually offer the lowest rates of the year. June and November are only slightly more expensive in most places, and early December can still be good value before Christmas rates start.
Storm risk. This is the key difference. Late August to mid-October is the statistical peak of the Atlantic season; June and November carry clearly less risk. If you are nervous about storms but still want low-season prices, the shoulder months are the safer bet.
Rain. All four months can be wet. November rain tends to ease through the month, while June typically sees the rainy season starting rather than at its height.
What is open. Closures for maintenance cluster in September and, to a lesser extent, October. In June and November almost everything is running, and cruise calls begin to return towards the end of the year.
Events. June has Fisherman's Birthday in Gouyave on 29 June. September and October have few festivals, only the solemn national days in October. November is quiet ahead of the Christmas season.
A flexible low-season week
A week in September or October works best with a loose plan that can be reshuffled day by day. On the first clear morning, take the boat trip or dive that matters most to you, whether that is the Underwater Sculpture Park, a sail along the south coast to Hog Island, or a snorkel at Morne Rouge. Fill the next days with short, flexible outings: Annandale Falls and Grand Etang lake on a dry morning, St George's and Fort George on a cloudy one, a chocolate estate or rum distillery when it rains.
Keep the longer drives, such as the loop to Sauteurs, Belmont Estate and River Antoine in the north, for a settled day, since the mountain roads are slower after heavy rain. Avoid scheduling anything important for the final day, and keep an eye on the forecast throughout; if a system is approaching, the decision to leave early is easier on day five than on day seven.
Frequently asked questions
Is September a bad month to visit Grenada?
Not necessarily, but it is the riskiest. September is usually hot, humid and wet, with the highest statistical chance of tropical storms. In return it brings the lowest prices and the emptiest beaches. It suits flexible travellers with insurance, not those who need certainty.
Do hotels close in Grenada in September?
Some do. A number of hotels, restaurants and smaller operators close for a few weeks in September or October for maintenance and staff holidays. Large resorts generally stay open. Always confirm with the property directly before booking, and ask whether restaurants and facilities will be running.
Is October good for diving in Grenada?
Often, yes. The water is warm, the Caribbean side is frequently calm, and dive sites are uncrowded. Rough days come with passing weather systems, and some operators reduce schedules, so check availability in advance and build spare days into your plans.
How hot is Grenada in October?
Expect daytime highs of around 30–32°C on the coast with high humidity and lighter winds than in winter, so it feels hotter than the thermometer suggests. Nights stay warm. Plan active outings for the morning and choose accommodation with air conditioning.
What is open on National Heroes' Day and Thanksgiving Day?
Both are public holidays, on 19 and 25 October. Government offices and banks close, and many shops and businesses do too. Hotels, many restaurants and some attractions continue to operate. Stock up on cash and essentials the day before.
