Now for the Wed pm Long Range Forecast:

SHORT TERM FORECAST (through Sunday, March 1st):
Highlights: Mid size SSW swell mix continues through the rest of the week. Small to locally fun size NW swell shows at well exposed spots.

South Pacific Swell: Old SSW swell (210-195) winds down going into the second half of the week, as a fresh shot of fun zone SSW(210-200) swell joins in. That sets up waist-chest-shoulder high surf on Thursday and Friday. The SSW swell holds those heights on Saturday then winds down by the end of the weekend, for slowly decreasing waves on Sunday.

Wind/Weather: Most areas through central and southern Costa Rica will see a diurnal wind pattern, with calm to locally light offshore flow for the early to mid mornings, before a light+moderate onshore sea-breeze gradually develops into the afternoon. NOTE - The wind will back off into the evenings for a glass-off for many locations before dark, especially the more sheltered/tucked away spots.

For northern Costa Rica look moderate to locally stronger offshore flow (strongest offshore flow for the northern half of the Nicoya Peninsula towards the Nicaragua border, lighter for the southern end) for the mornings. Afternoons turn to light+ onshores for lots of spots, as northernmost regions remain mainly offshore. 

Most of the region will see partly cloudy/sunny skies each day. However, there is still a chance for occasional passing thunderstorms/showers. Keep in mind that local storm activity can temporarily affect/change local wind conditions, as well as dirt roads due to rainfall.

EXTENDED FORECAST (Monday, March 2nd, and beyond):
Highlights: Solid Southern Hemi moves in next week.

South Pacific Swell: A good looking fetch has been aimed towards Central America this week by a storm over the central SPAC. That low is now starting to weaken as it slides further east towards South America. The healthy, long-period SSW(210-200) Southern Hemi swell starts to fill in next Monday, March 2nd, steadily builds in through Tuesday, then tops out on Wednesday with consistent overhead to double overhead zone waves at lots of well exposed spots while the better breaks see more size. That surf then gradually eases through the second half of the upcoming week. Stay tuned for the latest updates on this still active storm/swell system. 



Sat, 3/7/2015 shows 5 ft @ 15 sec SSW, Sun is 5 ft @ 14 sec SSW
 

Looks like we will continue to have surf... Friday's long range forecast update will provide higher confidence levels of the forecast.
