Happy New Years!
BOCA RATON, FL (Boca Post) (Copyright © 2025) — If you’re heading out tonight to ring in the New Year, consider this your reminder to dress like it’s actually winter—by South Florida standards, at least.
A dry, chilly air mass remains firmly in place over Boca Raton this evening as northwest winds usher in cold air to close out 2025. While the afternoon sun helped temperatures climb into the upper 60s, the warmth is short-lived. Once the sun sets, temperatures fall fast, and the clear sky offers little protection against the cold.
By late evening, Boca temperatures slide steadily through the 50s, settling near 46 degrees overnight. Areas west of the Intracoastal and closer to Lyons Road may feel even colder late, especially with light winds and dry air combining to make the chill more noticeable.
This is the kind of cold locals joke about—but also the kind that comes with real consequences. In South Florida, these temperatures are low enough for iguanas to stiffen up, lose their grip in trees, and occasionally drop without warning. It’s not uncommon on nights like this for wildlife officials to remind residents to watch sidewalks, patios, and parked cars beneath trees.
For people heading out—whether you’re walking downtown, waiting on rides near Mizner Park, or standing around at backyard gatherings—this won’t be a “Florida warm” night. Jackets, layers, and maybe even a hat won’t feel like overkill after midnight. Standing still outdoors will feel noticeably colder than earlier in the evening.
Northwest winds around 10 mph persist into the early evening before diminishing overnight. Even as winds relax, the dry air allows temperatures to fall efficiently. The result is a crisp, cold-feeling night that catches many people off guard.
Rain is not part of the picture. Skies remain clear through the night, making for good visibility for fireworks and celebrations—but also contributing to the fast cooldown.
New Year’s Day doesn’t bring much relief early on. Thursday starts cold, with wind chill values as low as the low 40s during the morning hours. Afternoon highs rebound only into the upper 60s, keeping conditions cool despite sunshine. Thursday night stays clear again, with lows near 51 degrees.
While Boca itself is not under a frost advisory, colder interior areas across South Florida are expected to see frost late tonight into early Thursday, underscoring just how strong this cold air mass is.
Along the coast, there’s another concern this evening. A high risk of rip currents remains posted for Palm Beach County beaches through early evening. Even with clear skies and cooler air, ocean conditions remain dangerous, and entering the water is strongly discouraged.
For boaters, hazardous seas and northerly winds earlier today gradually ease this evening and overnight, with conditions improving further Thursday. Still, caution remains advised until seas fully subside.
Looking ahead, temperatures slowly moderate heading into the weekend. Friday remains cooler than normal before readings climb closer to seasonal levels Saturday and Sunday. A weak front passes late Sunday into early Monday, reinforcing dry air but bringing no meaningful rain.
For tonight, though, the message is simple: it’s a cold New Year’s Eve by local standards. Bundle up, watch your step near trees, and don’t be surprised if the phrase “falling iguanas” makes a few rounds in conversation before midnight.
