BOCA RATON, FL (Boca Post) (Copyright © 2026) — A Dense Fog Advisory is posted this morning, then Boca Raton turns mostly sunny with highs in the upper 70s and a quiet, warmer pattern building through the week.

Advisories

A Dense Fog Advisory is posted this morning. Dense fog is still causing problems across Palm Beach County and nearby areas this morning, with visibility dropping to a quarter mile or less in some spots.

The Dense Fog Advisory remains in effect until 9 a.m., covering coastal, metro, and inland Palm Beach County, along with Glades and Hendry counties. That includes Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, Wellington, The Acreage, Belle Glade, and surrounding communities.

The biggest concern is driving. Low visibility can make roads hazardous, especially on early-morning commutes. Drivers are urged to slow down, use headlights, and leave extra space between vehicles until conditions improve later this morning.

Today’s Weather – Monday, January 5, 2026

It starts with fog. The kind you notice before you even check the temperature. Patchy to dense fog settled in overnight and is still hanging around early this morning, especially away from the immediate coast.

Early drivers should slow it down. Along I-95, westbound Glades Road, Lyons Road through the darker stretches — visibility can change quickly. Clear for a minute, then not. The worst of it usually runs from the pre-dawn hours through mid-morning, then improves once the sun gets some leverage.

After that, the day straightens out. Mostly sunny skies take over with a high near 77. Winds are light and variable at first, then turn east at 5 to 9 mph later in the morning. Enough to feel along the Intracoastal and beaches, but barely noticeable inland.

This is what a quiet pattern looks like. High pressure parked nearby, yesterday’s front already a memory. Temperatures inch upward. No rain to speak of. Nothing flashy.

Tonight stays calm. Mostly clear, with a low around 64. An east wind near 6 mph fades to light and variable after midnight. Clear skies, weak winds, dew points stuck in the low to mid-60s — that combination keeps fog in play again late tonight and early Tuesday. Mostly inland, but it could drift closer to the east coast metros. Not a guarantee. Just something to watch.

Otherwise, it’s a quiet stretch. Almost dull. People won’t complain.
