Quick Answer: The coldest month in Bonita Springs, FL

• Month: January

• Typical highs/lows: about 74–75°F / 54–56°F

• Rainfall: among the lowest of the year (dry season)

• Gulf water temperature: roughly 66–68°F

• Freeze risk: rare near the coast; brief chill during strong cold fronts

Why January wins (and why it still feels like vacation) Here’s the twist most people love: even in the coldest month, Bonita Springs Florida winter temperatures are what many folks up north call “perfect fall weather.” The Gulf of Mexico acts like a giant thermal battery, smoothing out extremes. When a winter cold front slides across the peninsula, coastal Bonita Springs, FL typically stays a bit milder at night than inland communities, and the afternoons rebound quickly into the 70s.

The data that matters (so you can plan smart) Using nearby long-term climate normals from NOAA for Naples Municipal Airport (APF) and Fort Myers/Page Field (FMY):

• Average January highs: 74–75°F

• Average January lows: 54–56°F

• Average January rainfall: about 1.5–2.0 inches (part of the region’s dry season)

• Gulf water temps: mid to upper 60s°F—chilly at first splash, comfortable once you’re moving

Freezing temperatures are rare along the immediate coast. A handful of winter nights can dip into the upper 40s, and on the strongest fronts, the upper 30s in spots—more likely inland than on the beach. Then, like magic, sunshine and 70s return. That “snap-back” is the Bonita Springs superpower.

A 48-hour cold front, decoded Picture this: It’s late January. A front rolls in Friday night and you’re reaching for a light sweater (the Florida kind). Saturday morning: 48°F at sunrise, bright skies by noon, and 68–70°F by afternoon. Sunday hits 73°F with low humidity and postcard light. By Monday—back to mid-70s. That’s the rhythm that keeps winter boating, beach walks, and open-house tours enjoyable.
