Climate & Weather Guide
Climate zones, seasonal temperatures, rainfall patterns, and best travel times in Grenada
Grenada, a small Caribbean island nation spanning just 344 km², features a uniform **tropical rainforest climate** (Köppen **Af**) ideal for expats seeking year-round warmth. Daytime temperatures consistently range from 30-32°C, with nights at 22-24°C, creating balmy conditions without true summer or winter seasons. The dry period (February-May) offers minimal rain and ample sunshine (up to 8 hours daily), perfect for outdoor living, while the wet season (June-January) brings heavier showers, peaking in November. Annual rainfall varies from 1200-1800mm, supporting lush vegetation but requiring mold awareness in humid homes. High humidity (70-85%) and trade winds provide cooling breezes, making it comfortable for residents despite the heat. Hurricanes are a seasonal risk (June-November), but infrastructure supports resilient living.

Coastal Lowlands
Covering most of Grenada's coastline and urban areas like St. George's, this zone enjoys steady sea breezes tempering the **tropical rainforest climate**. Daytime highs of 30-32°C pair with nighttime lows of 23-25°C year-round. The dry season (Feb-May) sees just 6-7 rainy days monthly with ~60mm precipitation, ideal for beach living and expat activities. Wet season brings frequent showers (up to 17 days in Nov) but rarely disrupts daily life due to quick-clearing storms. High humidity feels lush rather than oppressive, with consistent warmth supporting outdoor lifestyles, gardening, and water sports.

Interior Highlands
Grenada's hilly interior, including Grand Etang National Park, mirrors the coastal tropical climate but with slightly cooler nights (22-24°C) due to elevation up to 840m. Temperatures still hit 29-31°C daytime year-round. Rainfall is marginally higher (up to 1800mm annually), fueling waterfalls and rainforests, with the same dry (Feb-May) and wet (Jun-Jan) patterns. Expats appreciate hiking trails and fresh produce, though steeper terrain means more mist and occasional fog. Trade winds keep it comfortable, making it a refreshing escape from flatter areas.
Cooler, mistier highlands with verdant forests and invigorating hikes
Grenada's compact size delivers a consistent **tropical rainforest climate** across coastal and highland zones, with steady 27-32°C temperatures and breezy comfort year-round. Expats enjoy dry-season beach bliss and wet-season greenery, though hurricane preparedness is essential. Its warmth, natural beauty, and minimal variation make it highly appealing for relaxed island residency.
