October in Naples is a bit of a local secret, though it's getting harder to keep quiet. While the rest of the country is digging out sweaters and obsessing over pumpkin spice everything, we’re usually still in flip-flops. But it isn't just "summer-lite." There is a very specific shift that happens this month that can catch you off guard if you only look at the averages.
Honestly, the naples florida weather in october is the ultimate transition period. You’re basically watching the atmosphere wrestle with itself. On one side, you have the lingering, heavy humidity of the Caribbean summer. On the other, the first "cold" fronts (I use that term loosely) start peeking down from the north.
The Temperature Reality Check
If you check a weather app, you’ll see an average high of 83°F to 88°F. That sounds hot, and it is. But the real story is in the morning. At the start of the month, you’ll step outside at 7:00 AM and it feels like a warm, wet blanket. By Halloween, that morning air often drops into the high 60s.
That 10-degree difference is everything. It’s the difference between needing an extra shot of espresso to handle the swampiness and actually wanting to sit on your patio with a coffee.
- Early October: Highs of 88°F, lows of 74°F. Very muggy.
- Late October: Highs of 82°F, lows of 68°F. Much crispier.
It’s breezy, too. You get these steady winds off the Gulf—usually around 13 mph—that make the afternoons feel way more tolerable than August.
Rain, Hurricanes, and the Big Dry-Off
October is technically the "shoulder" of the rainy season. Typically, Naples sees about 3.8 to 4.3 inches of rain throughout the month. Compare that to the 8 or 9 inches we get in August, and you realize how much drier it's getting.

But here’s what most people get wrong: they think because the "daily 4:00 PM thunderstorm" starts to fade, the danger is over. It isn't. October is a massive month for tropical activity in the Gulf of Mexico.
While the Cape Verde storms out in the Atlantic start to fizzle, the Western Caribbean and the Gulf stay hot. Systems can spin up fast. We saw it with Hurricane Ian in late September and Milton in October. If you’re visiting, you have to keep an eye on the National Hurricane Center. It’s not just "rain" at that point; it’s a lifestyle of checking the "spaghetti models" over breakfast.

Water Temperatures: Is it Still Beach Weather?
Yes. 100%. The Gulf of Mexico is like a giant heat sink. It takes forever to cool down. In October, the water temperature at Naples Pier usually hovers around 81°F or 82°F.
It’s actually the best time to swim. The water is clear, the stinging jellyfish (sea nettles) from the heat of summer are starting to move on, and you don’t feel like you’re jumping into a hot bathtub. It’s refreshing but still warm enough that you don't need to "ease" into the water. You just dive in.
What You Should Actually Pack (The Non-Boring Version)
Don't just pack shorts. You'll look like a tourist—which is fine—but you’ll also be uncomfortable.
- The "AC" Layer: Florida restaurants keep their thermostats at "Arctic Tundra" levels. Even if it's 85°F outside, you will freeze inside a restaurant on 5th Avenue South without a light cardigan or a linen button-down.
- Linen is King: Cotton gets heavy when it’s humid. Linen stays light.
- The Rain Shell: You don't need a heavy raincoat. Just a cheap, packable poncho or a very thin windbreaker for those 20-minute afternoon bursts.
- Polarized Sunglasses: The glare off the Gulf in October is intense. Normal lenses don't cut it; you want polarized ones to actually see the turquoise in the water.
Why the Vibe Changes
Because the naples florida weather in october is so much better than the summer, the city starts to wake up. This is when the Stone Crab Festival happens (usually late October). The stone crab season officially kicks off on October 15th, and people treat it like a national holiday.
You also have the Naples International Film Festival and a bunch of Oktoberfest events. Because it's not "surface-of-the-sun" hot anymore, people actually want to be outside. You’ll see the sidewalk cafes at Third Street South filling up again.
Actionable Tips for Your October Trip
- Book the Boat Tour for the Morning: Even though the rain is less frequent, the Gulf is calmest in the morning before the sea breeze kicks up in the afternoon.
- Watch the "King Tides": October often brings exceptionally high tides. If you’re parking near the beach or a canal, check the tide charts so you don't end up with a soggy car floor.
- Sunscreen is Still Mandatory: The sun is lower in the sky, which means it hits you at a different angle, but it's still powerful. People get the worst sunburns in October because they "don't feel the heat" as much as they did in July.
- Download the "Clime" App: It’s great for tracking those fast-moving Gulf cells that don't always show up on national weather apps.
If you want the best of both worlds—warm water and manageable air—aim for the third week of the month. By then, the humidity has usually taken its first real hit, but the winter crowds haven't arrived yet. You get the city to yourself, and you can actually get a table at Campiello without a month-long reservation.
