Foggy Start, Sunny Finish: Monday’s Commute Alert and Afternoon Outlook

A Thick Blanket to Start the Work Week

Jacksonville residents waking up this Monday, March 2, 2026, are facing a challenging start to their commute. The National Weather Service has issued a Dense Fog Advisory for Coastal, South Central, and Western Duval County, effective through 9:00 a.m. Sea fog, which began rolling in from the Atlantic late Sunday evening, has moved significantly inland, dropping visibility to less than a quarter-mile in several areas across the First Coast.

Local authorities and the jacksonville.news weather team have designated this morning as a Weather Impact Alert period. Drivers are urged to exercise extreme caution on major thoroughfares like I-95 and I-10. Experts recommend slowing down, using low-beam headlights, and leaving plenty of following distance between vehicles to account for the sudden patches of near-zero visibility near the St. Johns River and coastal bridges.

Clearing Skies and Pleasant Afternoon Highs

Once the morning fog lifts after 9:00 a.m., the atmospheric pattern over Northeast Florida will shift toward a much brighter and more stable afternoon. As the low-level moisture dissipates, the heavy overcast conditions of the early morning will give way to mostly sunny skies by midday. The temperature will see a steady climb from a morning low of approximately 51°F to a comfortable afternoon high of 72°F.

Conditions will remain dry throughout the day with a 0% chance of rain, making it an ideal day for outdoor activities once the visibility issues subside. A consistent northeasterly wind will persist at 5 to 15 mph, providing a crisp, cool breeze that will keep the humidity at manageable levels. This transition marks the beginning of a mild trend for the first week of March, though coastal residents should note that sea temperatures remain a cool 66°F, which contributed to the morning's dense fog formation.

Evening Outlook and Nighttime Cooling

As the sun sets on this Monday, the clear skies will allow for a quick drop in temperature. By early evening, thermometers will hover in the low 60s, eventually dipping back down toward 52°F overnight. While another round of patchy fog is possible late tonight, it is not expected to be as widespread or impactful as this morning’s event. Wind speeds will decrease after sunset, leading to a calm and quiet night across the Bold City.
