Marine Weather and Tide Forecast for Valparaiso, FL

UPDATE
Issued at 530 AM CST Sun Nov 8 2026

Performed a brief update this morning. Many areas early this morning in the 40's with upper 30's for far northern areas/interior AL where a Frost Advisory remains in effect thru 7AM. We're on track to a beautiful Sunday with highs in the lower 70's underneath clear skies starting the day early this morning.
Proximity soundings indicate high clouds/cirrus will advect in later this morning into the afternoon hours, thanks to the same weak shortwave impulse over far northern Mexico assisting in advecting upper-level moisture across the mexican Plateau to the northern Gulf coast. This moist layer thickens later into the afternoon/evening with mixed layer alto stratus/cirrus overnight.
Otherwise, turning chilly yet again tonight into early Monday.

Worthy to note, proximity soundings illustrate relatively persistent H7 and above moist tropospheric layer with ongoing moisture advection aloft through the night. May need to monitor this, if clouds remain a bit thicker, that could offset some of the colder temperatures due to insolation, but for now, not very confident on how much cloud cover and to what degree (no pun intended) it'll play on temperatures as nearby high pressure will continue to promote cold air draining/settling into colder basins over northern areas. Something to make note of for now but will take a closer look later today for the possibility of additional frost advisories tonight. KLG

DISCUSSION
Issued at 1147 PM CST Sat Nov 7 2026

Cool, dry air continues to filter into the local area as high pressure maintains its hold over the central US. Temperatures through the remainder of the night, as well as Sunday night, should bottom out in the mid to upper 30s over our northern counties, and the low to mid 40s over our southern counties.
Although we are not anticipating temperatures dropping below freezing, temperatures in the 30s, nearly saturated boundary-layer conditions, clear skies, and light winds should help to support the development of frost over the northern half of our local area both nights. A Frost Advisory is in effect until 7AM Sunday morning generally for areas along and north of Highway 84. Another Frost Advisory may be needed for Sunday night for similar areas.
Highs on Sunday will be in the low 70s.

Temperatures slowly start to moderate through midweek as high pressure weakens and pushes directly overhead. Not anticipating any rain through Tuesday due to subsidence from the high overhead and very limited moisture. Highs are expected to reach the mid to upper 70s by Tuesday and lows should range from the low 40s north to the mid 50s along the coast by Tuesday night. One thing to note is that although temperatures are increasing, dew points should remain rather low for both Monday and Tuesday. This would lead to low RH values (~25-30% range). Although winds are expected to remain well below Red Flag criteria, these low RH values, along with dry antecedent conditions, may help to increase the risk for fire weather concerns.

By Tuesday night into Wednesday morning, a southern stream shortwave is expected to quickly push eastward. With upper-level flow turning more southwesterly ahead of this shortwave, some modest moisture return is anticipated prior to the shortwave's passage (PWATs increasing to around 1.0-1.2 inches). This may help to spark a few showers across the area, but overall, coverage should remain rather limited. The next big story will come towards the end of the week as a longwave trough quickly dives southeastward from Canada, digging as far south as the northern Gulf. A strong cold front looks to accompany this trough, pushing through the area sometime Thursday afternoon/evening. Long-range guidance continues to suggest that temperatures behind this front may drop to well below average by the upcoming weekend, bringing the potential for the first freeze of the season over northern portions of the area. Something we will continue to watch over the coming days.

The rip current risk remains low through Wednesday, possibly increasing to a Moderate Risk by Thursday. /96

MARINE
Issued at 216 AM CST Sun Nov 8 2026

High pressure will continue to settle into the region today revealing light winds and wave/seas. Winds increase tonight into Monday morning reaching 8-10kts for protected waters, to 10-13kts for outer waters but will be a short-lived window as winds relax going into the daytime hours on Monday. Next notable window of impacts will be expected Thursday morning as a front sweeps across the region, introducing increasing northwesterly/offshore winds. At this time, winds will likely reach Small Craft Advisory during the daytime hours on Thursday, with sustained winds 18-28kts for Gulf waters and higher gusts near 30 knots. Waves/seas respond reaching 2- 3ft for protected waters, 3-4ft for nearshore Gulf zones and 4-7 ft for outer Gulf zones. Winds and wave/seas taper going into next weekend. KLG
