Saint Lucia travel guide

Best time to visit Saint Lucia from the UK

Best value: May, Nov. Dec–Apr. Busiest and priciest: Dec–Apr.

Each bar is the average temperature in Castries for that month, and its colour shows the season for visitors: best value (good weather, fewer crowds and lower prices), busiest and priciest, or quiet (off-peak, sometimes because the weather is poorer).

• Our pick: May and NovemberThe warmest of the best-value months (28°C), with fewer crowds than peak season.
• Peak season: Dec–AprUsually 26–27°C. The busiest time, so book flights and rooms early and expect higher prices.
• Quiet season: Jun–OctAround 28–29°C. The cheapest and least crowded time, though often because of rain or heat.
• Warmest: September (29°C) · coolest: February (26°C)Temperatures barely change through the year, so the season matters more than the weather.
