08Editor's notes
What the numbers don't tell you
August is the peak of heat and humidity, with afternoons around 32 °C and heat indices well above that, and the start of the most active hurricane weeks. Miami Spice brings prix-fixe menus at the top restaurants from August through September, the one good reason to come, and hotel prices are at their lowest. Rain falls on about fifteen days, mostly as afternoon storms. Travel insurance and refundable rates are worth having.
Sea temperatures peak at 30 °C. The beaches are quiet on weekdays and busy with locals at weekends. The Everglades are wet, hot and buggy. Schools in Miami-Dade return in mid-August, so the family crowds disappear early. The Wynwood murals and the air-conditioned museums are the daytime circuit. September is statistically the riskiest month for hurricanes; see September.
