Marine Weather and Tide Forecast for Canal Point, FL

SHORT TERM
(Today through Tuesday)
Issued at 101 AM EDT Mon Aug 17 2026

Surface high pressure will remain in control early this week, with upper level ridging across the region. Latest models show Saharan dust will linger across South FL, which will also help aid in the suppression of convection today and Tuesday. Outside of a few mid to late day showers and storms along the sea breeze in SE FL, most of the area will remain dry again today. High temps will near record territory today, with middle 90s across the metro, to upper 90s over the interior. Combine those temps with dewpoints in the 70s, and max heat indices will again be in the 105-110 range this afternoon. A Heat Advisory will be in effect for all of South FL from 11 AM to 7 PM this evening. Mostly clear and mild overnight, with low temps ranging from the middle 70s over the interior to around 80 closer to the coasts.

On Tuesday a frontal boundary will slide from the TN valley to near the SE US coast. This will push some moisture further south down the peninsula by later in the day. Forecast soundings show PWAT values increasing to around 1.9 inches around the lake region, while remaining 1.6-1.7 inches over the far southern peninsula. With Saharan dust continuing to linger, expect another mostly dry day, however some scattered thunderstorms are possible late afternoon into the early evening around the lake region. With winds likely to remain westerly across the east coast metro throughout much of the afternoon, temps will likely be several degrees higher on Tuesday, with mid to upper 90s in the metro. Record high temps will again be in jeopardy. Max heat indices will again reach 105-110, so additional heat headlines will likely be needed.

LONG TERM
(Tuesday night through Sunday)
Issued at 101 AM EDT Mon Aug 17 2026

Upper level ridging starts to break down across the region mid to late week as a trough starts to dig into the eastern US, and remains there through next weekend. Meanwhile, the higher Saharan dust concentrations will get shunted to our south. Low level moisture increases across the area with near normal PoPs (40-60%) returning to the forecast during the extended period. Convection will be primarily diurnally driven sea-breeze convection each day favoring the afternoon and early evening hours, with isolated coastal showers and storms overnight.

Temperatures during the extended period will remain above normal, with max heat indices each day continuing to flirt with advisory criteria.
