What's the weather like in Miami in October?
Sitting in the southeast of the United States, Miami’s close to the Tropic of Cancer. This means that it has high temperatures all year round and October’s only a bit cooler than the height of summer. The summer months are the wettest so you'll get less rain as October goes on. When it does rain, it’s usually in short and heavy bursts or storms. The North Atlantic Ocean will help to keep you cool as it brings breezes and winds.
The average high in Miami is 29ºC in October, which cools to 23ºC at night. With these temperatures you should be fine in shorts and t-shirts in the evenings. The sea temperature’s 28ºC, which is perfect for swimming, while humidity’s high. There’s 144mm of rain over 14 days, and you can expect eight hours of sunshine from the 12 hours of daylight each day. UV levels will be very high so use plenty of sun cream. The sun goes down at around 7pm for most of October.
