When is the Best Time to Visit St Lucia?

St Lucia is a wonderful part of the Caribbean, known for having some of the most beautiful scenery and the most hospitable local people. If you’re thinking about a holiday to a Caribbean island then St Lucia should be on your list if you’re looking for brilliant beaches and an interesting culture, but when is the best time to pay a visit to the island?

As with many Caribbean islands, St Lucia experiences hot and tropical weather all year round, so there’s no ‘bad’ time of year to visit if you’re hoping for sunshine and high temperatures. However, there is a ‘rainy’ season that some tourists prefer to avoid to make the most of the Caribbean weather, which takes place between June and November.

Many people consider December to April to be the best time to visit St Lucia because the weather is driest at this time of year, but it’s still a wonderful destination all year round. In this article, we’ve explored the events, weather and best things to do each month so you can decide when to go to St Lucia to make the most of your trip.

Peak Season

If you’re looking for the best time to travel to St Lucia for the weather, the peak season is the ideal time for you to visit. Running from December to around March, there’s minimal rainfall, less humidity and lots of sunshine without it ever feeling too hot. The island will be busier around this time and you will have to pay peak season prices, but it’s well worth it for the endless days of sunshine and blue skies.

St Lucia in April

If watersports are on your holiday agenda then April is the best month to go to St Lucia, as the sea is at its warmest at this time of year.

Low Season

As we’ve already mentioned, there is no ‘bad’ time to visit St Lucia, so the low season is still a great time of year to come to the island. It’s the rainy season in St Lucia, but there’s a pretty low chance of any tropical storms, and you’ll benefit from a much quieter atmosphere as well as cheaper prices.

There’s also still plenty of sunshine and temperatures are actually at their highest at this time of year. So if you prefer your destinations to be quiet and are happiest in the heat, this is the ideal time of year to visit.

St Lucia in August

Despite being in the low season, August can still be quite a busy month in St Lucia as many families visit during the school holidays. The wet weather doesn’t last long enough to take any activities totally off the table, so if you’re planning on visiting the island with kids, August can be one of the best times to go to St Lucia.

St Lucia in September

If you’re planning on having a very laid-back holiday in the Caribbean then September is the best month to visit St Lucia.

October in St Lucia has very similar weather to the two months preceding it; there’s a fair bit of rain, humidity is high and you’ll get to enjoy bright sunshine and heat in between the showers. The average high temperature is 31°C and the average low temperature is 25°C, which will likely feel warmer when you’re outside because of the humidity and lack of a strong breeze.

St Lucia in November

If you’re wondering when to go to St Lucia to enjoy peak-season weather at a low-season price, the end of November is your best bet. The rainy season has meant that flora and fauna across the island are incredibly lush and beautiful, so it’s a great time to explore the landscape in between the dwindling rain showers.

Don’t be put off by the reputation of the rainy season in the Caribbean; showers are usually pretty short-lived and can provide a refreshing respite from the humidity.
