Bright Skies and Bitter Bites: Jacksonville Braces for a Midweek Freeze

A Cold Morning Start

Jacksonville residents are waking up to some of the chilliest temperatures of the season this Wednesday, January 28, 2026. While the sun is shining brightly over the River City, don't let the clear blue skies fool you. Morning temperatures have plummeted into the lower 30s, with some inland areas and neighborhoods near the St. Johns River reporting a hard freeze. This cold snap, which settled in earlier this week, continues to hold Northeast Florida in its grip, making for a very frosty commute for early-morning drivers and school buses.

Afternoon Warmth and Sunny Spells

As we move into the afternoon, the abundance of sunshine will provide some much-needed relief from the morning frost. However, the air remains crisp and winter-like. Expect the following conditions through the peak of the day:

• High Temperature: Reaching approximately 53°F to 55°F.
• Conditions: Mostly sunny with crystal clear visibility across the metro area.
• Wind: Light northwesterly winds around 5 to 10 mph, which will keep the wind chill feeling a few degrees cooler.
• Rain: A 0% chance of precipitation; the dry air mass remains firmly in place.

The afternoon high of 55°F is notably cooler than the typical January average, highlighting the strength of this current arctic air mass. Despite the cool temperatures, the lack of cloud cover makes it a beautiful day for outdoor activities, provided you are dressed in several layers. The UV index remains low, but the bright glare off the water and roads suggests keeping your sunglasses handy.

Evening Outlook and Overnight Freeze

Once the sun sets around the horizon, the temperature will drop rapidly. Because there are no clouds to trap the day's heat, we are expecting another night of radiational cooling. By 7:00 PM, temperatures will likely retreat into the mid-40s, heading toward a projected overnight low of 32°F to 34°F. Skies will remain clear and starry throughout the night, with no signs of fog or moisture expected before tomorrow morning.

Safety Reminders and Warnings

With freeze warnings and frost advisories being a significant concern during these late-January nights, local officials urge residents to prioritize safety. Be sure to check on the 'Four Ps': People, Pets, Plants, and Pipes. Ensure that elderly neighbors have adequate heating, bring all sensitive pets indoors, and cover any vulnerable tropical plants. While the region is currently experiencing a dry spell, the primary threat today remains the freezing temperatures. Stay warm, Jacksonville!
