Synopsis for the coastal waters from Bonita Beach to Suwannee River-
139 PM EDT Sun Oct 12 2025

.SYNOPSIS...

Seas will lessen to 2 ft or less by tonight and generally range
from 1-2 ft throughout much of the new week ahead with winds
mainly out of the northeast. In addition, high pressure to the
north of the area will also provide rain-free conditions
throughout the week. Winds and seas may increase by late week and
into next weekend as high pressure shifts east into the Atlantic
and a cold front approaches the area so chances for exercise
cautionary could increase by then.
