Grenada's air fares follow three calendars at once: the North American and European winter holiday season, the island's own festivals, and the movements of a large diaspora that comes home for Christmas and Carnival. On top of that sits the calendar of St George's University, whose students and visiting families fill flights at the start of each term and around graduations.
The result is that a week can be packed and expensive for reasons that have nothing to do with the weather. This guide goes through the year month by month, so you can see which weeks book out first and where the quieter, better-value windows lie.
December to April: the main season
December. Early December is still relatively quiet. From the middle of the month, flights fill with returning Grenadians and winter visitors, and the week between Christmas and New Year is the most expensive of the year on every route. Carriacou's Parang Festival, a celebration of Christmas string band music, also falls in December.
January. The New Year rush eases after the first week, but this is high season and the weather is at its most reliable. St George's University term starts bring students and families. Grenada Sailing Week usually takes place in late January or early February.
February. Independence Day is 7 February, with celebrations at the National Stadium and around the island. Carriacou Carnival takes place before Lent, so its dates move each year. European half-term weeks push fares up from the UK.
March. Dry, sunny and busy. Easter sometimes falls in March, and when it does, the week before becomes a peak period.
April. Easter weekend is a busy holiday on the island, with flights full in both directions. Late April is often a sweet spot: still dry, but past the main winter rush. Hotels often move to lower rates after Easter, and fares on the year-round routes from Miami, New York and London soften accordingly. Carriacou's Maroon and String Band Music Festival is usually held towards the end of the month.
May to August: shoulder months and Carnival
May. One of the best months for value. The dry season usually holds into May, hotels drop rates and flights from North America and Europe are easier to find. Winter-only routes have stopped, so options are narrower.
June. The rainy season begins, typically with short heavy showers rather than whole days of rain. Hurricane season officially starts on 1 June. On 29 June Gouyave celebrates Fisherman's Birthday, a lively local festival.
July. Fares start to rise in the second half of the month as the diaspora heads home for Carnival and North American and British school holidays begin. The rainy season continues, with hot humid days.
August. The peak of the summer season. Spicemas, Grenada's carnival, reaches its climax with J'Ouvert and the parades on Carnival Monday and Tuesday, normally in the second week of August, and the Carriacou Regatta Festival falls around the start of the month. Book flights and rooms many months ahead for these weeks.
September to November: the quietest stretch
September. After Carnival, the island empties of visitors. This is the heart of hurricane season and the lowest fares of the year are often found now. Some hotels and restaurants close for maintenance or holidays, so if you have a particular place in mind, check it is open. For divers and travellers who do not mind a shower or two, the empty beaches and lower prices make up for a lot.
October. Still quiet and still hurricane season, with frequent showers. Airlines switch to their winter schedules at the end of the month, so new routes and frequencies begin, sometimes at promotional fares. Thanksgiving Day, a public holiday, is on 25 October. Shops and offices close, so plan any errands around it.
November. The rains begin to ease and hurricane season officially ends on 30 November. Prices climb in the last two weeks as the winter season starts, but early November can still offer good value with seasonal routes already running.
How far ahead to book
For peak weeks, meaning Christmas and New Year, Easter, and the Spicemas period in August, book as soon as your dates are fixed. Seats on direct flights from New York, Miami, Toronto and London can sell out months ahead, and the cheap fare buckets go first. Six months ahead is not excessive for Christmas.
For the main winter season outside holidays, booking three to five months ahead usually secures reasonable fares. For the shoulder months of May, June, September, October and early November, two to three months is often enough, and last-minute deals occasionally appear.
Remember that accommodation follows the same pattern. On Carriacou in particular, where the number of rooms is small and recovery from Hurricane Beryl in July 2024 has taken time, rooms for the Regatta and Carnival can be harder to find than flights. Secure the room and the ferry or domestic flight together.
A useful habit is to set fare alerts on two or three routings at once, for example via Miami, via New York and via Barbados, and to compare the total cost including bags. Fares on single-carrier routes such as Toronto or London rarely fall close to departure in busy months.
What the seasons mean for flying
Weather rarely stops flights into Grenada outright. In the dry season, from roughly January to May, the trade winds blow steadily and flights run on time unless a delay comes from elsewhere in the network. In the rainy season, heavy afternoon showers can briefly hold aircraft on the ground or make approaches bumpy, but disruption is usually measured in minutes.
The serious exception is a tropical storm or hurricane. When a system threatens the southern Windward Islands, airlines may cancel or bring forward flights and the airport can close for a day or two. Airlines usually issue travel waivers allowing free date changes once a named storm is forecast near the island. Keep your booking flexible in August, September and October, and watch the forecasts in the week before travel.
Saharan dust also drifts across the Caribbean in early summer, producing hazy skies. It seldom affects flights, but it is worth knowing about if you have asthma or simply expect crystal-clear views from the window seat.
Pitfalls when choosing your dates
Assuming hurricane season means storms all the time. Most days in the season are warm and sunny with passing showers. The risk is real but occasional. Buy travel insurance that covers weather disruption, and watch forecasts in the days before you travel.
Forgetting the university calendar. St George's University term starts and graduation weeks fill flights and rooms around True Blue and Grand Anse. If your dates are flexible, check them against the academic calendar.
Arriving on a public holiday. Arriving on Independence Day, Emancipation Day or Carnival Tuesday is lively, but offices are closed, some shops shut and roads around parade routes can be blocked.
Planning around seasonal flights that may not run. Winter routes are announced each year. Do not assume a route that ran last winter will return on the same days.
Overlooking the ferry or domestic flight to Carriacou. If your trip includes the sister islands, the onward connection from the main island has limited capacity and fills up on festival weekends. Book it with the same urgency as the international flight.
Frequently asked questions
What is the cheapest month to fly to Grenada?
September and October usually bring the lowest fares, as they fall in the quietest part of hurricane season after Carnival. Early May and early November are also good-value months with more reliable weather. Prices vary by route, so compare a few weeks.
When is Spicemas in Grenada?
Grenada's carnival, Spicemas, builds through late July and early August and peaks on Carnival Monday and Tuesday, normally in the second week of August. Flights and accommodation book out early, especially from New York, Toronto and London.
Is it risky to visit Grenada in hurricane season?
Grenada lies south of the islands most often hit, but storms do occur, as Ivan in 2004 and Beryl in 2024 showed. Most days in the season are fine. Travel insurance that covers disruption and flexible bookings reduces the risk.
When is the best weather in Grenada?
The dry season, from roughly January to May, has the most sunshine and lowest humidity. December can still see showers. The rainy season from June to December brings short heavy downpours, higher humidity and greener landscapes.
How early should flights be booked for Christmas in Grenada?
As early as possible, ideally six months or more ahead. The Christmas period combines winter visitors and Grenadians abroad travelling home, so direct flights from North America and London fill early and fares rise sharply.
