The weather and its seasons. Grenada boasts comfortable to hot weather year round. Expect temperatures that range from 32 C during the day in summer to as low as 20 C overnight in winter.
Rainfall varies each year, and showers show up in short bursts, so travelers shouldn't be discouraged from visiting during the summer. Grenada lies on the edge of the hurricane belt, so the island can be affected by bad weather and storms. Hurricane season falls during the rainy season, from about June to November.
