Jacksonville woke up in a gray-out early Sunday, March 1, 2026, with thick, patchy fog, low clouds, muggy air and temperatures hovering near 55°F across much of the metro. Visibility is poor in low-lying areas and along the St. Johns River, so expect a slower-than-usual ride through the morning rush up to about 9 a.m.
Afternoon Conditions
Once the fog finally burns off by mid-morning, skies are expected to turn mostly sunny, with highs near 71°F at the beaches and mid to upper 70s inland. Readings should dip a few degrees late in the day along the river and coast. A light northeast onshore breeze of about 3 to 12 mph will keep coastal neighborhoods noticeably cooler than spots farther inland.
Fog And The Morning Commute
A Dense Fog Advisory is in effect through 9 a.m. local time, with patchy to locally dense fog capable of cutting visibilities to a quarter mile or less in places. Drivers are urged to slow down, stick with low-beam headlights and allow extra stopping distance. For the full advisory and the latest updates, see the National Weather Service in Jacksonville.
Warming Trend This Week
Temperatures climb steadily through the week, with inland highs expected to reach the upper 70s to low 80s by Tuesday and near-record warmth possible Thursday and Friday. Later in the week, scattered sea-breeze showers or an isolated inland thunderstorm could pop up, and a strengthening onshore flow will push up surf and rip-current risk. For more background on the pattern shift, see our earlier look at first frost then a blowtorch.
Plan Ahead
If you are planning to hit the beach or head out on the water, check lifeguard and marine advisories and delay any outing if visibility is still poor. Surf is expected to trend higher into the week as onshore winds strengthen. Keep an eye on local forecasts through the morning commute and later in the week for warmer, breezier conditions that could affect outdoor plans.
