Climate & Weather in St. George's

Good to Know

  • Best time to visit is February to April: driest period with warm temperatures and lowest rainfall risk.
  • Avoid October and November if possible: peak rainfall months with highest precipitation and humidity (up to 172–207 mm per month).
  • Hurricane season officially June–November with peak risk August–October, but Grenada's southern position in the hurricane belt means direct hurricane hits are rare (only 5 in 70 years).
  • Temperature variation throughout the year is minimal (~2°C (36°F) / 3.5°F), so trip timing is better decided by rainfall preferences than temperature.
  • Shoulder season (May and late November–December) offers decent weather with fewer crowds and lower prices, though expect occasional tropical showers.
  • Afternoon thunderstorms are common year-round but typically brief; they usually give way to sunshine.
  • Sea remains warm and swimmable year-round (26–29°C (79–84°F) / 79–84°F), making water sports viable throughout the year.
  • Spice­mas Festival in late July to August brings crowds despite being in the rainy/hurricane season; expect higher humidity and rainfall but also vibrant celebrations.
  • Wind is steady year-round, making conditions generally pleasant; very little variation between seasons except during hot/wet period.
