Synopsis for the E Pacific within 250 nm of Mexico
753 PM PDT Thu Aug 20 2026

.SYNOPSIS...Fresh northerly gap winds will continue to pulse to
strong winds over the Gulf of Tehuantepec during the overnight
into the early morning hours through the next several days, with
seas occasionally building to rough. High pressure will begin to
build back modestly across the Baja offshore waters Fri
afternoon through Sat night to produce a more typical moderate
to fresh NW wind flow there. Southerly wind flow will return to
the Gulf of California Sat night and become fresh to locally
strong Sun. Winds and seas are expected to build across the
outer offshore waters of southwestern Mexico tonight into early
next week in association with a developing area of low pressure
moving westward and just outside of the offshore waters.
