September in Florida: Late-Summer Heat, High UV & Sun Safety Tips
As summer slowly gives way to fall, September still packs plenty of sunshine and heat in the Sunshine State. It’s a transitional month where hurricane season peaks, afternoon storms roll through, and the UV index remains at summer-like levels. Here’s what to expect and how to prepare for it.
Average Weather in September
- Highs: 88–91°F (31–33°C)
- Lows: 74–76°F (23–24°C)
- Max UV: 9–10 (Very High)
- Humidity: High, often in the 70–80% range
- Rain: Frequent afternoon thunderstorms, especially early in the month
September still feels like full summer in Florida. Heat and humidity remain intense, and while storms are common, mornings and early afternoons are usually sunny and hot, keeping UV levels consistently high.
UV Index in September
Expect maximum UV levels to range from 9–10 on most days, occasionally reaching 11 early in the month on very clear days. Peak hours run from 10 a.m. to 2 p.m., but keep in mind that UVB rays, which cause sunburn, remain strong until about 4 p.m. During this time, unprotected fair skin can redden quickly, so everyone should limit midday exposure and take steps to protect their skin.
Sun Protection Tips for September
Before planning your September activities, keep these sun safety reminders in mind:
- Treat this month like midsummer: wear UPF 50+ shirts, wide-brim hats, and UV-blocking sunglasses.
- Apply broad-spectrum sunscreen (SPF 30+) to all exposed skin, and reapply every two hours or after swimming/sweating.
- Schedule outdoor activities earlier or later in the day to avoid peak UV hours.
Following these habits will help you enjoy the sunshine safely while minimizing your risk of overexposure.
October in Florida: Comfortable Weather, Strong Sun & How to Protect Yourself

- Highs: 82–86°F (27–30°C)

UV Index in October
Maximum UV levels generally range from 6–9, which is considered high to very high. Even though the temperatures feel cooler, UV rays remain strong enough to cause skin damage within 15 minutes.
Sun Protection Tips for October
Before heading outdoors in October, keep these practical sun safety reminders in mind:

- Pack a lightweight, breathable UPF layer for all-day outdoor activities.
- Keep sunscreen and sunglasses handy for festivals, markets, and beach days.
These simple steps will help you enjoy Florida’s fall activities without risking sun damage.
November in Florida: Mild Days, Moderate UV & Smart Sun Habits
November marks the true arrival of Florida’s comfortable fall season. The intense heat has faded, the air feels crisper, and the weather invites more time outdoors. While the sun may not feel as harsh, UV rays are still present and worth protecting against. Here’s what you can expect this month.
Average Weather in November
- Highs: 75–79°F (24–26°C)

Expect maximum UV levels between 4–7 on most days. While this is lower than summer, it’s still high enough to contribute to cumulative sun damage, especially with extended outdoor exposure.
Sun Protection Tips for November
Before stepping out in November, keep these sun protection reminders in mind:
- Maintain your year-round sun safety routine; cooler weather doesn’t mean lower risk.
- Wear sunglasses and UPF clothing when spending extended time outdoors.
