Miami weather in September
“Mild and bright — an underrated time to visit.”
Roughly 24 rainy days across the month, on average.
September in Miami is hot and humid, with average highs of 30°C (86°F) and lows of 25°C (77°F). Expect significant rainfall—around 203mm spread across roughly 24 rainy days—though you'll still enjoy about 10 hours of sunshine daily. The heat and moisture create that classic tropical feel, with afternoon thunderstorms a near-daily occurrence. Pack accordingly for warm, wet conditions.
This is Miami's off-season, so you'll find fewer tourists and lower prices across hotels and restaurants. The atmosphere is more relaxed and local-focused. However, September falls within Atlantic hurricane season, so weather can be unpredictable. Most visitors skip this month, making it ideal if you prefer quieter beaches and want to save money.
For 2026, consider visiting if you're budget-conscious and don't mind rain. The storms are usually brief and warm, perfect for cooling off. Book accommodation with indoor activities nearby—museums, shopping, or dining—in case weather disrupts beach plans. Travel insurance is recommended given hurricane season timing.
