Marine Weather and Tide Forecast for Lealman, FL

AVIATION
(12Z TAFS)

VFR conditions to continue with westerly winds and mainly FEW-SCT clouds. Mid day rain chances less than 20% today, so will keep mention out of TAFs for now.

.SHORT TERM (TDY-WED)...
Issued at 326 AM EDT Tue Aug 18 2026

It is already fairly warm with temperatures across the Peninsula ranging from the mid to 70s inland to low to mid 80s near the coast.
Upper level ridge remains across the Gulf and south Florida. This will keep drier air south of I-4 and SWFL. As a result, the highest rain chances today will be over the interior and the East Coast. In addition, this will also support dangerous heat, which prompted the issuance of another Heat Advisory through 7PM this evening.
Residents and visitors should remain hydrated and take frequent breaks if planning to spend time outdoors. Today will likely be the warmest day for the week. Afternoon temperatures could hit record levels, especially over interior locations. Heat indices will get up to 112 degrees.

On Wednesday, the ridge begins to weaken as an U/L disturbance pushes into the Southeast. Moisture increases gradually from north to south and onshore flow remains allowing higher rain chances near the coast overnight/early and pushing inland/east into the afternoon and evening. Increasing clouds will help temperatures a few degrees lower.

.LONG TERM (THU-MON)...
Issued at 326 AM EDT Tue Aug 18 2026

Later in the week, high pressure remains west and several disturbances attempt to make it into the area. Moisture continues to increase and rain chances remain area-wide with onshore flow prevailing. The slightly lower temperatures may keep us just below advisory criteria, but it will still feel very uncomfortable.
Temperatures will be in the low to mid 90s through the rest of the period.

MARINE
Issued at 326 AM EDT Tue Aug 18 2026

Issued at 326 AM EDT Tue Aug 18 2026
