Issued at 540am EDT Sat August 1 2026 Another night of shower-free KBYX radar. While the Atlantic surface ridge continues to dominate our weather not much has changed in the last 24 hours. Winds along the Reef are light and variable. Temperatures are in the lower to mid 80s. Today we can expect similar conditions to continue though off the Upper Keys there could be another slight freshening of breezes in the afternoon. Waterspout formation is possible again if a cloud line is able to develop from the light and variable winds.

Early this week the mid level trough will still be in place over the southeast and in the Gulf waters though mid level ridging will attempt to push back in the region. Surface high in the western Atlantic will result in winds becoming more easterly to southeasterly and slightly freshening around Monday. Moisture will move into the area and rain chances will gradually increase this week though models are suggesting higher than what we have advertised. Easterly winds will continue through a majority of the week and rain chances will peak on Wednesday through Thursday. Thereafter, mostly sunny skies will return with near normal rain chances.

Issued at 540am EDT Sat August 1 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, weak nebulous flow with light to gentle breezes will continue as the western periphery of an Atlantic surface ridge slides westward across the Keys putting the coastal waters in a col region. As high pressure strengthens in the North Atlantic, southeast breezes will freshen by the second half of the weekend and into early next week. In addition, rain chances will also be increasing by next week as deeper moisture spreads into the region ahead of a frontal boundary approaching northern Florida.
