Click here for current weather in Bermuda and a 5-day forecast. Though the chances of a hurricane are slim, September is the likeliest month for one.
The weather cools slightly in September from its August high. Although with a daily high air temperature of 29°C (84°F), September is one of the year’s hottest months. Most cruise ships are still visiting the island, and although the summer season is drawing to a close, hotels are still charging peak rates.
The water temperature is around 27°C (81°F), which is excellent for swimming and snorkelling. Underwater visibility is around 100 feet, and divers will feel comfortable in a shorty.
Expect around seven hours of sun each day, about average for the year.
Sunrise is around 7 am, and sunset is approximately 7:30 pm.
Events taking place include Harbour Nights. The seasonal ferry from the Royal Naval Dockyard to St George is operational.
The only public holiday in September is Labour Day.
While Bermuda is a small island, there can be slight variations in weather conditions across different areas. The south shore beaches may experience stronger winds than the more sheltered north shore. Hamilton, being more built-up, can sometimes feel a degree or two warmer than coastal areas due to the urban heat island effect.
September is a good month for deep-sea fishing, with plenty of blue marlin and yellowfin tuna. September 1 is the first day of Bermuda’s 7-month lobster season. You can now try Bermuda’s delicious spiny lobsters at restaurants.
September falls within Bermuda’s hurricane season. In recent years, several devastating hurricanes have hit Bermuda during this month. The worst was Hurricane Fabian in 2003. It hit the island directly, causing four deaths. Hurricane Emily in September 1987 also caused significant damage.
The chance of a destructive hurricane is still relatively small, and the island’s buildings are constructed to withstand them. Any damage tends to be to power lines, trees etc.
The Bermuda Weather Service provides excellent real-time updates and storm tracking during hurricane season.
