Central America and Mainland Mexico Short-Range Surf Forecast

Large S (180-195) are expected to start easing through the end of the week blending with smaller/moderate sized SW (210-220) that will arrive Wednesday and build to a peak Friday.  Another small S (180-190) is due over the weekend.  Long-range models don’t show much new noteworthy swell until around the end of the month.  Read more for details.


The S swell currently in the water is going to back off through the end of the week as I mentioned, but should blend together with a new SW (210-220) that should be arriving Wednesday.  The mix should help maintain moderate sized surf through the end of next week.  Wave heights for the exposed coast are expected to be running waist to chest high+, with some standouts seeing set waves in the head high to overhead+ range.  The swell will start to decline over the weekend as a smaller S (180-190) fills in blending with those leftovers.  It’s likely that wave heights are going to back off into the knee to chest high+ range for typical spots.  Some models are showing increased winds over the outer waters, potentially driving some added local wind swell out of the S-SW, but you’ll have to keep an eye on local conditions for that feature.

Tropical Outlook

Doesn’t look like either of these lows are going to experience enough of the optimal conditions for strengthening that they will need in order to become tropical cyclones in the next few days.  If they do, its likely that they will be too far west to bring any noticeable swell to Mainland Mexico.

North Pacific Swell Forecast

North Pacific isn’t showing much of anything.

South Pacific Swell Forecast

The forecast remains on track for being pretty lame.  We’re still on track for some weak SW due on the 24th.  It’s looking pretty weak though, likely going to bring some more waist to head high surf to standouts.  The main feature is a balled up trough of low pressure off the coast of Chile early next week.

Most of the energy is going to be focused straight at Central Chile, but some of the fetch will break off to send some inconsistent moderate sized surf for around the 25th/26th.  It’s still a bit too early to call, and it’s not looking all that exciting so we’ll have to wait and see how it plays out.  Stay tuned.

Next long-range forecast expected for Friday the 18th of July.
