Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
431 AM EDT Mon Jun 29 2026
.SYNOPSIS...A broad high pressure system centered over the North
Atlantic will continue to extend westward to the Florida Peninsula
through today. This will support bouts of light to gentle breezes
that may freshen to gentle to moderate at times. Starting late
tonight, a frontal boundary will press south across the Florida
Peninsula and stall across central Florida. This will act to
weaken the high and allow for slackening breezes through Thursday.
Thereafter, breezes will resume a cycle of overnight peaks and
daytime lulls.
