Marine Weather and Tide Forecast for St. James City, FL

DISCUSSION
Issued at 139 PM EDT Mon Mar 9 2026

Strong ridging will remain over the area through Wednesday. This will keep the near record breaking high temperatures in place each afternoon with highs near 90 degrees away from the coast. The main difference for the first half of the week will be the lack of shower activity that we have seen since last Thursday. Even through we see a similiar PW values and a seabreeze setting up the 500 mb temperatures has warmed a few degrees. That doesn't seem like a big chance but it will keep us more stable which will prevent the showers from forming.

Our next cold front is expected to push through on Thursday. As it does do we should see a line of showers and storms push through the area sometime during the day that should give us some beneficial rain once again. This cold front will help to at least bring temperatures back down to average for next Friday. Another cold front will start to push through the southeast for the weekend which will allow the warmer and moist air to return. We will not see record highs but temperatures will get into the mid 80's with scattered showers each afternoon and evening.
