Marine Weather and Tide Forecast for Jupiter Inlet Colony, FL

DISCUSSION
Issued at 655 PM EST Mon Jan 19 2026

Tonight...With mostly clear conditions forecast, temperatures will efficiently drop into the 30s and 40s after midnight. HRRR guidance points to a 10-20% chance (or less) of reaching freezing in far northwestern Lake and Volusia counties. However, areas of frost is possible north of I-4 and patchy frost surrounding urbanized metro Orlando extending south into rural portions of Osceola/Okeechobee counties. There will also be a northerly breeze overnight between 5 and 10 mph (up to 15 mph at the coast). Over the interior, this light breeze and cold temperatures will combine to produce wind chill values in the upper 20s to near 30 degrees.
Thus, another Cold Weather Advisory has been issued for Tuesday morning, stretching from inland Volusia County to Lake Okeechobee.
Areas closer to the coast will be chilly but not cold enough to experience these sub-30 degree wind chills.

Tuesday-Wednesday...High pressure is forecast to drift toward the Mid Atlantic by Wednesday with its influence keeping conditions dry locally. A gradual warmup ensues, bringing us closer to normal high temperatures by Wednesday afternoon in the low to mid 70s.
The pressure gradient around the southern periphery of the high tightens up a bit, particularly tomorrow, leading to 10-15 mph north-northeast winds and gusts 20-25 mph (occasionally 30 mph at the coast). Clouds develop along the Treasure Coast Tuesday afternoon, followed by an overall increase in low and high level clouds Wednesday as moisture increases. Isolated showers return to the forecast Wednesday night from Sebastian Inlet southward, though confidence is low in rain amounting to any more than a few hundredths of an inch.

Thursday-Sunday (modified)...Surface high pressure weakens mid to late week but is still forecast to maintain a weak influence on our local conditions. A weak area of low pressure is forecast to develop near the Bahamas late this week, eventually washing out into a nearly stationary boundary across the Atlantic, extending toward the Florida Peninsula. Locally, northeast flow is anticipated to continue advecting moisture towards the area and when coupled with some energy aloft traversing the peninsula on Thursday, will lead to a low chance (20-30%) for shower development (favoring coastal locations).

By Friday, lingering moisture along the boundary and onshore flow will bring another day with low chances for showers, especially at the coast. A cold front is forecast to approach north Florida and slow down Saturday into Sunday. There are inconsistencies in the medium range regarding timing and when this front actually reaches central Florida. However, rain chances reach 15-25% across the north by Sunday as the front slowly works southward. Check back for future updates on when this front may finally push through the area and if any additional moisture along the front affects rain chances early next week.

Temperatures continue warming through Saturday, reaching above normal values areawide late this week into the weekend. Then, a return to colder weather arrives gradually next week.

MARINE
Issued at 300 PM EST Mon Jan 19 2026

Poor to hazardous boating conditions remain through late afternoon and early this evening, primarily south of Sebastian Inlet. Waves of 5-7 ft will slowly recede, despite northerly winds remaining 15-18 kt through the overnight period. Poor conditions return to much of the local Atlantic tomorrow morning as north-northeasterly winds freshen again, with Small Craft Advisory conditions possible by tomorrow afternoon (especially in the Gulf Stream). Seas build 6-8 ft in the Gulf Stream in response to breezy/gusty conditions.
Winds then decrease from Wednesday night onward as high pressure weakens over the local waters. Seas fall below 6 ft by Friday with generally favorable boating conditions continuing into the first half of the weekend.

Isolated to scattered showers are forecast beginning Wednesday night and continuing intermittently through at least Saturday. No lightning storms are anticipated at this time.

FIRE WEATHER
Issued at 300 PM EST Mon Jan 19 2026

Dry conditions persist Tuesday with relative humidity values falling into the 30 percent range north of I-4. With a north- northeast breeze 10-15 mph, sensitive fire conditions may develop in the afternoon. From Wednesday onward, moisture begins to return to the area, lowering fire weather concerns.
