Orlando has a subtropical climate which roughly divides into two major seasons: one is hot and rainy from May until October and the other is cooler from November through March with more moderate temperatures and less frequent rainfall. Orlando’s warm and humid climate is caused mainly by its position which is relatively close to the Tropic of Cancer with much of its weather affected by the movement of the Gulf Stream.

On average there are 233 sunny days a year in Orlando, with the July high is around 93º and the January low at 49ºF.  During the height of Orlando's humid summer season temperatures rarely fall below 70 °F (21°C), with daytime highs averaging 90ºF.  During these months strong afternoon thunderstorms occur almost daily, often bringing with them high winds, damaging rainstorms and lightning.

During the winter season the humidity is lower and temperatures are more moderate with average night time lows in January at around 50 °F (10°C), and average daytime highs at 72°F (22 °C). Temperatures rarely drop below 32 °F (0°C), but the city can drop below freezing maybe once or twice a year.

The average annual rainfall in Orlando is 128cm, with most of it occurring in the period from June to September. The months of December through May are Orlando's driest season.
Orlando has a considerable hurricane risk, although not as high as in South Florida’s other coastal regions. Since the city is located 64 km inland from the Atlantic and 60 miles 97 km from the Gulf of Mexico, hurricanes usually weaken before arriving in Orlando.
