Swell Forecast:

Today (Friday) the SW that began filling in midweek, should be holding size, as it fills in with 13-second periods from 204 degrees.  This event should start to back down Saturday afternoon and evening. 

Further out, the models early Tuesday showed another pulse for the 14th from 202 degrees.  This system has a less than ideal trajectory for the Central American coast though, and could prove to be another smaller swell.  Periods should start filling in at around 15 seconds on Sunday.  Then they look like they could hold through Monday, before slowly backing off into the middle of next week.

Beyond that, a couple more small to moderate background pulses are on the radar for mid next week.  One of these pulses looks like it could ramp up the surf a bit mid week.  The system is due to start filling in on the 16th, picking up steam on the 17th showing periods around 16 seconds fro 211 degrees.  The swell should continue to increase in size through next Thursday.  It looks like size could hold Friday before backing down next weekend.

On the long-range models (72 hours out) the system I am suggesting off the SE coast of New Zealand, is ramping up according to the models.  The fetch is now suggested to reach sea heights of 40+ feet.  This changes the previous calculations, and suggests a swell arrival for around the 22nd from 222 degrees.  Periods could be in the 18 to 20 second range.  It looks like the swell should hold some decent size even after traveling the 5700 miles across the South Pacific.  I’ll report further on this in my next report.  Stay tuned for more updates on this one.

Weekly Outlook:

Today (Friday the 12th) SW continues to hold in the chest to head high range at stand out breaks.  Periods should be around 13 seconds from 204 degrees.

Saturday the 13th SW continues to slowly back off down to the waist high+ range.  Periods drop down to 12 seconds from 201 degrees.

Sunday the 14th a new pulse of 15-second groundswell should start to fill in from 202 degrees.  Size is expected to be moderate with wave heights in the chest to head high range at stand out breaks.

Monday the 15th the pulse of SW from 202 degrees holds in the chest to head high range with periods around 15 seconds. 

Tuesday the 16th size starts to back down to the waist high+ range through most of the day.  Later in the evening it looks like there could be a small pulse of SW from around 206 degrees arriving picking the surf back up to chest high+ overnight.  The new groundswell from 211 degrees is expected to start filling in late as well, although size should start out relatively small I believe.

Wednesday the 17th the new groundswell from 211 comes into play, ramping the surf up to the head high and overhead+ range.  Periods should be around 16 seconds. 

Thursday the 18th the SW from 211 continues to hold size as periods hold around 16-seconds.

Beyond the southern hemi models are starting to warm up a bit, and it looks like there could be a couple of pulses for late next week, with another decent groundswell pulse due for around the 22nd.  Stay tuned for updates

That's it for today, be safe, and get in the water!
