Marine Weather and Tide Forecast for Port St. Joe, FL

SHORT TERM
(Today and Tonight)
Issued at 151 AM EDT Tue Jun 9 2026

Isolated to scattered showers and storms are forecast again, with the best chances along and west of the Flint and Apalachicola Rivers. Abundant cloud cover should temper temperatures some this afternoon with middle 80s across our Georgia counties and upper 80s to lower 90s for those that see a bit more sunshine.

Rain chances today are thanks to an H5 shortwave overhead and mean RH in the 1000-700 mb layer running between 80 to 90 percent. It's also worth noting that the steering flow for any showers and storms today will be quite weak, so they won't move a whole lot.
Precipitable Water values (PWATs) near 2", or above the 90th percentile for this time of year, means locally heavy rain is a concern within any showers and storms that develop.

LONG TERM
(Wednesday through Monday)
Issued at 151 AM EDT Tue Jun 9 2026

The rest of the work week's forecast greatly depends on the location of an H5 along the northern Gulf Coast. If it's situated more overhead, rain chances would decrease slightly. On the flip side, if the H5 ridge is more west of the region, that'll leave just enough of a weakness overhead to allow for scattered showers and storms each afternoon. In both scenarios, temperatures would run in the lower to middle 90s, with slightly warmer temperatures in the drier scenario.

Beyond that, ensembles show a broader trough developing over the eastern half of the country. Cluster analysis highlights the fact that the EURO ensembles are wetter than their GEFS counterparts. So we'll keep elevated rain chances in the forecast this weekend into early next week. Temperatures should nudge down a few degrees with the increased rain chances over the weekend, or upper 80s to lower 90s.

Isolated showers and storms are forecast along the sea breeze Wednesday through Friday. Transport winds will primarily be out of the east to southeast around 5-10 mph over the next few days, turning more onshore closer to the coast as the sea breeze moves inland.

HYDROLOGY
Issued at 151 AM EDT Tue Jun 9 2026

Locally heavy downpours are expected within any showers and storms that develop the next several days with 1" to 2" of rain occurring very quickly. However, there is not a widespread threat of flash flooding at this time.

Severe to exceptional drought continues for areas generally east of the Apalachicola and Flint Rivers as these areas missed out on the most beneficial recent rains. The drought features long term impacts that are affecting rivers, lakes, and ponds that are still below normal despite recent rains.
