August (along with July) is Bermuda’s hottest month. The average daily high temperature is 30°C (86°F), and the average daily low temperature is 26°C (79°F).
Tourists are on the island in significant numbers. The great weather means hotel rates and airfares are high. Cruise ships are visiting the island.
The water is also at its warmest (28°C / 82°F). It’s a great time to go snorkelling, although visibility has dropped to around 75 feet.
Visitors can expect around eight hours of sunshine every day.
Sunrise is around 6:45 am, and sunset is about 8 pm. A complete list of sunrise and sunset times can be found here.
The most severe sun is between 10 am and 2 pm. To avoid sunburn, use sunscreen and take extra care in areas that don’t usually see the sun.
August is one of the most humid months of the year.
The month falls within official hurricane season, though the likelihood of one (still rare) is higher later in the year.
Events taking place in August include Harbour Nights, the Horseshoe Bay Sandcastle Competition, and Bermuda Pride.
In August 1934, American explorer and marine biologist Charles William Beebe descended 3,028 feet into the ocean off the coast of Bermuda in a spherical submersible called the Bathysphere. He set the world record for the deepest dive by a human. A replica of the Bathysphere is on display at the Bermuda Underwater Exploration Institute.
Bermuda’s highest-ever recorded temperature (34°C/93°F) occurred in August 1989.

Packing Suggestions
For an August visit to Bermuda, pack light, breathable clothing suitable for warm weather. Include swimwear, sun protection (high SPF sunscreen, sunglasses, and a hat), and perhaps a light raincoat or umbrella for occasional showers.
Evening air temperatures remain warm so that you won’t need heavy clothing, but a light sweater or jacket might be useful for air-conditioned indoor spaces.
