September is a pretty good month for deep-sea fishing with plenty of blue marlin and yellowfin tuna in the water. 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 4 deaths. Hurricane Emily in September 1987 also caused significant damage.
The chance of a destructive hurricane is still quite small though and the island’s buildings are constructed to withstand them. Any damage tends to be to power lines, trees etc.
