Montserrat has a tropical climate, typical of the Eastern Caribbean, with warm temperatures year-round, high humidity, and distinct wet and dry seasons. The island’s weather is strongly influenced by trade winds, altitude, and occasional volcanic activity from the Soufrière Hills volcano.
1. Temperature
- Average daytime highs: 28°C to 31°C (82°F to 88°F)
- Nighttime lows: 22°C to 25°C (72°F to 77°F)
- Temperatures are relatively consistent throughout the year.
2. Seasons
Dry Season: January to May
- Sunniest and most pleasant time.
- Lower humidity and less rainfall.
- Peak tourist season.
Wet Season: June to November
- Hotter, more humid, and rainy.
- Tropical showers—often brief but heavy.
- Increased risk of hurricanes, especially August to October.
3. Winds and Breezes
- Constant northeast trade winds moderate the heat.
- Provide a cooling effect, especially on coastal areas.
4. Volcanic Influence
- The Soufrière Hills volcano (active since 1995) occasionally releases ash and gas, especially during eruptions.
- This can affect air quality and visibility in the southern part of the island.
5. Hurricane Season
- Official season: June 1 to November 30
- Montserrat, like much of the Caribbean, is vulnerable to hurricanes and tropical storms.
- Emergency systems are in place to handle severe weather.
6. Microclimates
- Coastal areas: Hotter and drier.
- Interior hills and northern uplands: Cooler and wetter, especially in higher elevations like Silver Hills.
- Exclusion zone (southern part): Limited habitation and subject to localized weather due to volcanic conditions.
