Orlando Weather In September: What To Expect

Planning a trip to Orlando in September? You're likely wondering about the weather. September in Orlando typically means warm temperatures, high humidity, and a good chance of afternoon thunderstorms. It’s a transitional month, moving from the peak of summer heat into a slightly milder, though still very warm, autumn.

This guide will break down everything you need to know about Orlando weather in September, including average temperatures, rainfall, humidity, and what to pack to ensure your trip is as comfortable as possible. We’ll also cover hurricane season considerations and how to make the most of your visit despite the weather.

Understanding Orlando's September Climate

Orlando’s climate in September is characterized by its subtropical nature. While it's technically autumn, the weather still feels very much like summer for most of the month. The transition is gradual, with heat and humidity lingering.

Average Temperatures in September

Expect daily high temperatures to hover around the low 90s Fahrenheit (around 32-33°C). Nighttime lows usually drop into the mid-70s Fahrenheit (around 23-24°C). The overall average temperature for the month is typically around 82°F (28°C). This means warm days and balmy nights, perfect for evening strolls or enjoying theme park entertainment after dark, provided you stay hydrated.

Rainfall and Thunderstorm Patterns

September is one of Orlando’s wettest months, averaging around 6-7 inches of rain. This precipitation often comes in the form of short, intense afternoon thunderstorms. These storms are usually caused by the buildup of heat and humidity throughout the day, leading to rapid cloud development. While they can be dramatic, they typically don't last long and often clear up quickly, leaving behind cooler, fresher air.

However, it’s important to remember that September is still within the Atlantic hurricane season. While major hurricane landfalls are not a daily occurrence, the possibility exists, and tropical storm systems can bring prolonged periods of rain and wind. Staying informed about weather forecasts is crucial.

Humidity Levels

Humidity remains high in Orlando throughout September. You can expect relative humidity levels to be in the 70-80% range, especially during the morning and after storms. This high humidity can make the temperatures feel even warmer than they actually are. Staying hydrated and seeking air-conditioned environments during the hottest parts of the day is highly recommended.

• Rain gear: A lightweight, packable rain jacket or a poncho is a must. Umbrellas are also useful for navigating between attractions during downpours.
