Climate and monthly weather forecast
St.George's, Bermuda

St.George's, located in the Bermuda Islands, demonstrates a distinct humid subtropical climate, denoted as Cfa under the Köppen climate classification. Being an island territory situated in the North Atlantic Ocean, its climate is significantly influenced by maritime factors. Oceanic winds serve to moderate its climate, leading to relatively stable, mild conditions throughout the year.

The climatological parameters bring to light that sea temperatures show a cyclical pattern varying from 19.2°C (66.6°F) in February to a peak of 27.8°C (82°F) in August and September. In comparison, daylight hours increase significantly from 10.3 hours in January to a maximum of 14.3 hours in June before taking a dip during the latter half of the year.

On dissecting these climate attributes, an observed trend is the close interrelation between sea temperatures and daylight hours. In general, the Bermuda summer months (May to September) offer warm sea temperatures above 24°C (75.2°F) coupled with long, sunny days, providing ample opportunities to indulge in outdoor and water-based activities. However, the winter months (November to early March) carry a milder climate with shorter daylight hours, underlining the clear seasonal divisions of the region.
