FZPQ50 PGUM 070655 SRFGUM Surf Zone Forecast for the Mariana Islands National Weather Service Tiyan GU 455 PM ChST Thu May 7 2026 .DISCUSSION...There is a high risk of rip currents along east and north facing reefs due to an elevated east-northeast trade swell, which is expected to persist into the weekend. As the trade swell eases slightly, the reduced effect of island wrap-around will allow surf to diminish below hazardous levels of 9 feet along north facing reefs late Friday afternoon. There is also a moderate risk along south-facing reefs. Elevated trade winds and swell, and associated surf will persist through the weekend. $$ GUZ001-MPZ001>003-072200- Guam-Rota-Tinian-Saipan- 455 PM ChST Thu May 7 2026 ...HIGH SURF ADVISORY NOW IN EFFECT UNTIL 4 PM CHST FRIDAY ALONG NORTH FACING REEFS... ...HIGH RISK OF RIP CURRENTS THROUGH SUNDAY AFTERNOON ALONG NORTH AND EAST FACING REEFS... 36 hour Surf Zone Forecast for the Marianas from 600 PM Thursday through 600 AM Saturday .TONIGHT...
