If you’re planning a weekend outdoors in Jacksonville, Saturday will be your golden opportunity to soak up the sun. But don’t get too comfortable! A sharp drop in temperatures is heading this way, and by Sunday, you might be reaching for a jacket. It’s a classic Florida weather switch-up, and if you’re not paying attention, it could catch you off guard. Whether you’re planning a beach day, a backyard barbecue, or a relaxing evening out, here’s what you need to know about this weekend’s changing forecast.
Saturday’s Forecast: Warm, Sunny, and Ideal for Outdoor Plans
Saturday, March 1, is shaping up to be a beautiful day in Jacksonville. Temperatures will climb to a comfortable 78°F (26°C), with clear blue skies and gentle breezes. It’s the kind of weather that makes you want to head to the beach, take a stroll along the Riverwalk, or fire up the grill.
Humidity levels will stay relatively low, making the warmth feel pleasant rather than sticky. Winds will be light, around 5-10 mph, meaning no major gusts to worry about. If you’ve been waiting for a picture-perfect day to be outdoors, Saturday is your chance.
But don’t let the sunshine fool you—big changes are on the way.
Sunday’s Forecast: A Cold Front Moves In – Big Temperature Drop Ahead
By Sunday, March 2, Jacksonville will feel like a completely different place. A cold front is expected to push through overnight, bringing a noticeable temperature drop. The high for Sunday will struggle to reach 68°F (20°C), and by the evening, temperatures will plummet to 46°F (8°C).
That means you’ll wake up to a crisp, much cooler morning, and if you’re heading out in the evening, you’ll want to have a sweater or jacket handy. Winds will shift to north-northeast at 10-15 mph, bringing in that cool, dry air and making it feel even chillier.
Why Is Jacksonville’s Weather Changing So Fast?
This dramatic temperature shift is the result of a cold front moving down from the north. As warm air lingers over Florida, the sudden arrival of cooler air will push out the heat and drop temperatures quickly. The result? A near 30-degree difference in just 24 hours!
Jacksonville is no stranger to these quick weather swings, but that doesn’t mean you shouldn’t be prepared. If you’re heading out Sunday morning, don’t expect the same warmth you felt on Saturday afternoon.

How to Stay Comfortable and Safe This Weekend
- For Saturday: Enjoy the warmth! Whether you’re heading to the beach, park, or a festival, this is the best day to be outside. Just wear sunscreen because the clear skies mean higher UV exposure.
- For Sunday: Dress in layers! The morning may feel cool, but the evening will be much colder than what Jacksonville residents are used to. If you’re planning to go out for dinner or a night event, bring a jacket.
- Watch for Wind Gusts: As the cold front moves in, expect breezier conditions Sunday afternoon and evening. It won’t be extreme, but it’ll make it feel even cooler than the temperature suggests.
- Be Cautious on the Roads: Sudden weather shifts can lead to slick spots or reduced visibility. While rain isn’t expected, morning dew and temperature changes can create fog in some areas.
Final Thoughts: Two Different Days, One Weekend – Plan Accordingly!
Jacksonville is in for two completely different weather days this weekend. Saturday will be warm, sunny, and perfect for outdoor fun. But by Sunday, a cold front will sweep in, bringing a sharp temperature drop.
If you love warmth, soak up Saturday while it lasts. If you prefer cooler weather, Sunday will be your kind of day. Either way, just make sure you’re prepared for the switch
