Central America and Mainland Mexico Short-Range Surf Forecast

The small to moderate mix of SW (215-225) already in the water and newly arriving SSW-SW (210-220) should help increase wave heights a little bit on Wednesday.  Additional SSW (190-210) will blend in for Thursday.  As those swells start to ease into the weekend we’re expecting another round of S-SSW (185-200) to arrive and help maintain moderate sized surf Saturday and Sunday before easing into mid-next week.  Read more for details.


Wave heights should be running waist to chest high+ at standouts currently, but will pick up over the next couple days as the new mix of SSW (190-210) starts building with longer periods Wednesday.  Wave heights are likely to increase at standouts into the chest high to overhead+ range along the exposed coast.  Standouts could be seeing sets going head high to well overhead as the swell peaks in the 4-4.5 foot range with 15 second periods Thursday.

Friday a more southerly pulse from the S-SSW (185-200) arrives with long periods.  This new energy is going to mix in with the leftover SSW-SW and help boost wave heights a little more through the weekend, peaking on Sunday with around 4.5 to 5 feet of deepwater energy at 15 to 16 second intervals.  That means standouts should continue running head high to well overhead, while the exposed coast sees chest to overhead surf.  It looks like a few magnets and deepwater spots could see larger sets in the double overhead to double overhead+ range even.  Size is expected to max out Sunday before easing more Monday through mid-next week.

North Pacific Swell Forecast

North Pacific isn’t showing much of anything.

South Pacific Swell Forecast

Long-range models aren’t showing anything too exciting.  A weaker fetch south of the Pitcairn Islands/Easter Island could send some smaller S-SSW (185-200) towards the region for around the 26th/27th.

East of New Zealand there’s another trough expected to also kicked up some bigger fetches, but none of them are angled in the right direction.  High pressure south of French Polynesia is going to force that area of fetch down towards the building ice shelf, which is likely to help generate stronger winds, but the current slushy state of the ocean down there isn’t going to allow for much swell production… on top of the fact that the fetch ends up being zonal.  So long-story short, unless there are some changes in the next few days to the storm track, we’re not likely to be receiving any note worthy swells before the end of the month.  Stay tuned.

Next Forecast should be expected on Friday the 19th.
