08Editor's notes
What the numbers don't tell you
September is statistically the most likely month for a hurricane to affect South Florida, and the quietest for visitors. It is still hot, around 31 °C, wet, with rain on about fourteen days, and humid. Miami Spice continues through the month with its set menus, and rates are rock-bottom. If you book, choose refundable fares and watch the National Hurricane Center from a week before departure.
Labor Day weekend at the start of the month is the one busy stretch, with the beaches and hotels full of regional visitors. Sea temperatures stay around 30 °C. Many attractions run reduced hours. Daylight drops to around twelve hours by the equinox. For the same low prices with lower risk and easing humidity, late October is the better gamble, and November is the first dry-season month.
