Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
848 PM PDT Mon Jun 30 2025

.SYNOPSIS...Moderate to fresh NE to E winds are expected in the
Papagayo region through Wed. Winds may increase to strong
speeds, with moderate to rough seas by Wed night into Thu due to
the pressure gradient between a ridge to the N and a low
pressure along the monsoon trough. Elsewhere, gentle to moderate
winds and moderate seas in southerly swell are expected.
Moderate to rough cross equatorial S to SW swell will affect the
waters between Ecuador and the Galapagos Islands over the next
several days.
