What’s the weather like in St Lucia in October?

Sitting in the eastern Caribbean Sea near the North Atlantic Ocean, St Lucia is close to the equator and has a tropical climate and high temperatures. St Lucia has two seasons rather than four; a wet season from June to November and a dry season from December to May. This means that October’s one of the wettest months, but you’ll still see lots of sun at this time and north easterly winds will help to keep you cool.


The typical high in St Lucia is 31ºC in October and things stay lovely and warm in the evenings with temperatures only dropping to 23ºC at night. The sea temperature is 29ºC, which is perfect for swimming, while humidity’s high. There’s 192mm of rain over 20 days, although you can still look forward to 12 hours of daylight with seven hours of sunshine each day. UV levels will be extremely high so use plenty of sun cream. Sunset’s just before 6pm at the start of October.
