In October, Orlando transitions from its summer humidity to a more pleasant autumn, but it is rarely "cold" in the traditional sense. The average nighttime low temperature in October 2026 is approximately 18°C (64°F). While the daytime remains warm (around 28°C/82°F), the evenings can feel "crisp" once the sun goes down, especially if you are in a breezy area like a theme park or near a lake. You will likely not need a heavy coat, but a light sweater or hoodie is highly recommended for late-night events like Halloween Horror Nights. Interestingly, as of February 27, 2026, Orlando's current low is 17°C, which aligns perfectly with those typical October nighttime expectations. It is the perfect weather for outdoor dining, provided you have a light layer handy for the occasional cool northern breeze that signals the start of the Florida fall season.
