Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
427 PM EDT Thu Jul 2 2026
.SYNOPSIS...Generally light east to southeast breezes will become
variable at times through Friday. Any active weather over the marine
zones will largely be limited to possible afternoon nearshore
cloudlines interacting with any boundaries pushing off the South
Florida Mainland through the evening hours. High pressure will
gradually build back across the Florida Keys coastal waters late in
the week. This will support generally light to gentle east to
southeast breezes resuming across the Keys marine zones.
