085 FZPN27 KNHC 180911 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 211 AM PDT Sat Apr 18 2026 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-182115- Synopsis for the E Pacific within 250 nm of Mexico 211 AM PDT Sat Apr 18 2026 .SYNOPSIS...Fresh to locally strong northwest winds will occur near Cabo San Lucas through early Sat. Northwest swell will briefly impact the waters west of Baja California Norte through early Sat. Otherwise, rather quiet conditions will remain over the Mexican offshores through the weekend. Looking ahead, high pressure building over the Gulf of America is expected to induce a strong to near gale force Tehuantepec gap wind event beginning Sun night into Tue. Northwesterly swell will move into the area Tuesday night and range between 6 to 8 ft through the remainder of the forecast period. Otherwise, high pressure will dominate the general weather pattern into the middle of next week and support moderate to fresh winds across the area. $$ PMZ009-182115- Mexico Border S to 30N within 60 nm of shore- 211 AM PDT Sat Apr 18 2026 .TODAY...N of 31N, variable winds less than 5 kt.
