Marine Weather and Tide Forecast for Jupiter Island, FL

DISCUSSION
Issued at 201 PM EDT Wed Apr 23 2025

Current-Fri...Surface high pressure continues to weaken and trend further seaward, though will be reinforced again off of the mid Atlc coast. A weak surface front stalled across the Deep South will transition to a warm front on Thu and lift northward. High pressure in the mid-levels over the Bahamas will weaken and flatten a bit as mid-level impulses traverse the southeast U.S. and off of the coast.
The persistent warm, dry, and stable conditions continue. Still keep PoPs absent from the grids/zones through this period. Max temps each afternoon in the L80s at the coast thanks to a daily sea breeze, and M-U80s into the interior, perhaps a few L90s well inland. Min temps continue in the 60s areawide, except around 70F across adjacent barrier islands. Likely to be breezy along the Space & Treasure coasts each afternoon.

Continued low humidity and drying fuels will promote sensitive fire weather conditions, especially across the interior. SE winds 5-10 mph shift E Thu/Fri and increase to 10-15 mph (some higher gusts) as the sea breeze moves inland each afternoon. Burn bans continue across several east central Florida counties including Lake, Seminole, Orange, Volusia, and Brevard.

Sat-Wed
Slightly Modified from Previous
A weak cold front moves across the southeast U.S. this weekend with high pressure building quickly behind. The next chance for mentionable precip returns Sun and Mon as the front approaches the local area. Increasing PWATs to around 1.2-1.3" combined with diurnal heating and boundary interactions should be sufficient enough to support a low chance (10- 20%) of showers on Sun. Global models continue to suggest a better and increasing chance of showers on Mon (20-30%) as onshore flow develops. Ridging aloft amplifying across the FL peninsula looks to suppress precip chances through the remainder of the extended period. Temperatures in the L90s across the interior warm and peak on Sun before falling into the M-U80s Mon-Wed. A similar trend is noted along the coast this weekend, and highs in the L-M80s on Sat peak in the M-U80s on Sun. Coastal highs then cool slightly to L80s Mon-Wed. Lows remain mostly in the L-M60s through the weekend and warm into the M-U60s next week.

MARINE
Issued at 201 PM EDT Wed Apr 23 2025

Slightly Modified from Previous...SERLY winds "back" east (10-15 kts) Thu and into late week as high pressure retreats seaward.
Seas of 2-3 ft increase to 3-4 ft overnight. Building seas peak around 5 ft offshore Thu night and Fri before gradually subsiding to 3-4 ft through the weekend. A weak cold front approaches the local waters late this weekend with rain chances returning early next week.

AVIATION
(18Z TAFs)
Issued at 200 PM EDT Wed Apr 23 2025

Prevailing VFR conditions are forecast with high pressure (~1020mb)
over the SW Atlantic. The potential (20-30%) exists for MVFR CIGs at times into THU AM after 08Z at the coastal TAF sites. Generally, E winds at 10-14kts with gusts to 15-20kts this evening are expected weaken tonight and become light and VRB (except KSUA) after 06Z before increasing into THU afternoon at 5-10kts and into the PM at 9-14kts

FIRE WEATHER
Issued at 201 PM EDT Wed Apr 23 2025

Slightly Modified from Previous...Warm, dry, and stable conditions are forecast through the remainder of the week. Fire sensitive weather conditions continue with min RH values as low as 35-45 percent across the interior each afternoon. Onshore winds increase to 10-15 mph as daily sea breezes develop and progress inland. A weak cold front approaches east central Florida late in the weekend and early next week, with isolated to scattered showers returning to the forecast Sun (10-20%) and Mon (20-30%). Generally Good to Very Good smoke dispersion is forecast.
