CRNW 2017-0303 (Fri am) Forecast & pm Update


NOTE: Keep in mind the general Galapagos shadowing effect which resides in the 200-210 degrees spectrum. While we are directly affected by this spectrum the edges are less impactful but would decrease wave size. So, for Saturday I expect us to receive swell but, of course, we will observe greater energy at the Outer Wash than at The Wash proper.

Effective Friday evening        
 FORECAST HIGHLIGHTS 
  • Fun SSW swell for weekend
  • Best winds/conditions in AM hours
  • More fun size swell in long range (11th-15th) 
SHORT TERM FORECAST: (through Tuesday, March 7th)                        

South Pacific: Overlapping SSW swells (210-190) will hold over the weekend, setting up more fun size surf that should be a notch or two above the swell we have seen the past couple days. Satellite data and the Chile Buoy indicate this run of swell will be in line with, or even slightly better, than current swell model guidance.

Look for plenty of waist-head high surf on Saturday at the better breaks, while standout spots see some slightly larger sets. That surf is up a touch on Sunday with chest-head high surf at exposures and sets running overhead at standout spots during favorable tides.

Surf eases into the new week but staying relatively fun for many spots with waist to head high waves on Monday morning. Fading SSW swell leftovers heading into Tuesday, mainly in that thigh to chest high zone.

Wind/Weather: A diurnal pattern prevails across much of Costa Rica through over the weekend. Mornings will start with light/variable to light offshore flow, winds trending onshore by the middle of each day before a light to moderate onshore sea-breeze develops in the afternoons.

For northernmost CR, look for steady and breezy offshore flow to persist. Note - winds veer onshore in the afternoon around Playa Grande/Playa Negra.

EXTENDED FORECAST: (Wednesday, March 8th, and beyond)   
       
South Pacific: Smaller SSW swell leftovers for mid to back half of week with modest to locally fun waves for exposures. Expect mostly knee to chest high waves over this period(Wed-Thur) before our next series of swells build in for the weekend.

While there is still nothing major on the radar, it does look likely that we'll see a continuation of fun size, or slightly better, surf for the middle part of March. Current model guidance points to a series of SW to SSW swells from the 11th-16th that look similar in size to what we expect over this weekend (details above), possibly a bit better.

There is decent model agreement on the size/strength/track of the storms in the SW South Pacific that will create these swells (and overall pattern in the SPAC), so we're medium confidence of at least fun size surf (chest-head+ high at the good breaks). All in all, looking like a great month to be in Costa Rica. Stay tuned, we'll refine details in the next few updates.
