Surf Zone Forecast for the Mariana Islands
National Weather Service Tiyan GU
443 AM ChST Thu Jul 10 2025

.DISCUSSION...A low risk of rip currents continues along all reefs
and could become moderate along east facing reefs Friday night due
to a small increase in trade swell. Surf along west and south facing
reefs may also increase slightly as a minor southwest swell reaches
the Marianas over the weekend. Due to the unsettled weather pattern
in the region, there will be a moderate risk of lightning over the
next several days.

* Low Risk of rip currents - Strong currents can still occur near
jetties and reef channels. Always have a flotation device with you
in the water.

Moderate Risk of rip currents - Wave conditions support stronger or
more frequent rip currents. Always have a flotation device with you
in the water.

High Risk of rip currents - Large waves will produce strong rip
currents, especially along narrow reefs and beaches. Rip currents
will be life threatening. If caught in a rip current, swim parallel
to the beach rather than against the current.
