Marine Weather and Tide Forecast for Bayport, FL

DISCUSSION
Issued at 230 PM EDT Mon May 18 2026

Our summertime convection looks to be getting starting for the early part of the week with increase moisture and an active seabreeze. Our flow will generally be out of the east through Wednesday. This will favor west coast showers and storms during the afternoon and evening hours with inland area mainly staying dry.

As we head into Thursday and Friday we will see an upper level low move into the northern Bahamas. The first thought would be this will increase shower chances. However the low actually shifts our upper level winds more northerly bringing a little bit of drier air and keeping storms chances pretty limited (20 to 30%). The only exception with be Southwest Florida where we still keep some high moisture along with high storm chances.

As we head into t upper level flow switches to the southeast and the weekend moisture comes back with PW reaching around 1.75. This will allow for scattered showers and storms with the highest chances still along the west coast. However, the higher PW will still bring some storms in inland locations mainly in the afternoon hours.

Issued at 230 PM EDT Mon May 18 2026

Newest hi res model guidance showing moisture increasing slightly along the west coast this afternoon. Because of this we have introduced a prob30 group for both TPA and PIE. Sites south of that will be seeing a VCTS as storm chances will be higher the farther south you go. Winds will be out the east with occasional gusts up to 20 knots.



MARINE
Issued at 230 PM EDT Mon May 18 2026

Winds will be mainly out of the east for much of the week around 5 to 15 knots with winds shifting southeast on Friday. Our main concern to boaters will be afternoon and evening storms that push off of land and and into the Gulf. Some of these storms could cause frequent lightning and strong winds.

FIRE WEATHER
Issued at 230 PM EDT Mon May 18 2026

Increased moisture with summertime convection will help to minimize fire hazards this week. Highest rainfall totals during this week should be along the coast with inland areas staying mostly dry.
