St. Lucia weather faqs featured image

One of the most important deciding factors when booking your tropical St. Lucian vacation is the weather.

Chances are, you would prefer every day to be sunny with clear skies and calm seas. While St. Lucian weather isn’t always perfect, it definitely beats cold winters and grey, rainy days.

We know that there are tons of questions that you may have about St. Lucian weather and we’re here to help.

Here are the answers to some frequently asked questions about our weather.


In St. Lucia, the wall outlets used at various places of accommodation varies, but the primarily used standard is British (220v) outlets.

If you’re coming from the US you might not be able to plug your devices to charge without an adapter.

The same goes if you are coming from the UK you might also have difficulty getting charging spots since some lodging areas use US (120v) outlets.

It’s best to be on the safe side and travel with a universal adapter. You can’t simply purchase these at the airport like other countries. We recommend the one below.

Does St. Lucia have seasons?

Most countries where visitors come from are usually in the temperate zone and experience four seasons – spring, summer, autumn, and winter.

Unlike these countries, St. Lucia is located in the tropical zone, and therefore we only have two seasons – the wet (rainy season) and the dry season.


What are these seasons like?

The wet and dry season each lasts six months. The rainy season starts on June 1st and ends on November 30th. These are the summer months and some autumn months.

The rainy season is characterized by more rainfall and can reach averages of 193 mm in the middle of the season. Storms, hurricanes and other smaller weather systems occur during the rainy season.

In recent years, most storms and hurricanes usually occur in the later months of the rainy season.

The dry season spans from December 1st to May 1st. These are the rest of the winter months and spring. There is significantly less rainfall in these months, and prolonged droughts may occur.

For some residents, this means that the water supply from the local water company may be rationed. However, all hotels have safe and clean water supplies on site which will be used in the event of a drought.

If you’re staying at a villa, guest house or Airbnb type location, there will most likely be water tanks – but it’s always wise to ask beforehand.


What is the average temperature in St. Lucia?

On average, St. Lucia’s temperature ranges from 26˚ – 29˚ Celsius or 79˚ – 83˚ Fahrenheit. November is usually the hottest month while January is often the coldest.

Although St. Lucia is located in the tropical zone, the winter weather in countries to the north do affect our temperatures.

From December to April, temperatures usually range from 26˚ – 27˚ C or 78˚ – 80˚ F. If you’re used to staggering low winter temperatures, this would still be hot weather for you – but you may overhear some St. Lucians noting that it’s a bit colder.

It’s also important to note that the sun begins to set earlier during the later months of the year, and it may be dark by 6 p.m. This might be an important detail when planning your activities if you do decide to come St. Lucia during those months.


What is the best time to travel based on the weather?

There are many factors about the weather that you may want to consider when booking your trip. There are several pros for coming to St. Lucia in either the wet or dry season.

Most visitors try to avoid the harsh winters at home, and come to St. Lucia between December and April – the dry season.

While it may be busier than the other months of the year, you can enjoy cooler months and the risk of your vacation being disrupted by a storm or hurricane is greatly reduced.

The months of June to November are great times to visit if you want to enjoy typical St. Lucian weather.

Although it is the rainy season, many days out of the month are still sunny and conditions are often ideal for lots of activities like water sports and hiking.

While St. Lucia has been slightly affected by the rains and winds associated with storms, the last few years have been notably calm.

If you are fearful of the weather during the wet/rainy season, keep in mind that weather systems are followed for days in advance so there is always time to get out.

Popular things to do and places to go are open year round, and nothing is indefinitely seasonal so this doesn’t have to be a deciding factor in making your decision.


What should I pack for each season?

The attire worn in St. Lucia hardly varies by the seasons. Light clothing is preferred year round, but some accessories might differ based on the time that you come to St. Lucia.

Here are some recommended items that you may want to include:

Dry Season:

  • Sunscreen
  • Large hats or caps
  • Sun umbrellas
  • Sunglasses
  • Reusable water bottles (insulated to keep water cold)

Wet/Rainy Season

  • Large umbrella
  • Rain jacket
  • Appropriate footwear – rain boots are optional
  • Quick drying or moisture wicking clothing
