CRNW Forecast of 2016-0517a, Tue



This is a mash-up of the Mon evening long-range forecast and the Tue morning short-range forecast table. The long-range periodicities don't look so hot, but has The Cove ever let us down?

Effective Monday afternoon
SHORT TERM FORECAST (through Thursday, May 19th)
Highlights: Fresh SW/SSW swell peaks and holds into Tues; Another Southern Hemi pulse due back half of the week. 

South Pacific Swell: Fresh SW swell (220-210) tops out over tonight and into Tuesday. This is from a storm that took a favorable track toward Central America last week, although the Galapagos Islands will likely again take a bite of the size and consistency. At this point we expect to see chest-shoulder-head high surf at the better breaks on Tuesday, with top spots through North CR up to a couple feet overhead on sets. 

As the current, SW swell trends down on Wednesday, a new SW swell (220-210) starts to show in the afternoon. Look for many breaks to be chest-shoulder-head high range for the first part of the day with potential for larger sets in the afternoon.

This energy tops out over Thursday/Friday with more consistent waves in the shoulder-head high range, while standout southerly exposures go 1-2 feet overhead. This storm looks to be a bit smaller than the previous swell, but look for more fun to mid size surf throughout the region. 

Wind/Weather: Diurnal wind pattern for the start of the week for Central and South CR with wind ranging from light/variable to light offshore in the early mornings, before trending onshore mid mornings. A light+/moderate onshore sea breeze develops over the afternoons.

For North CR look for morning offshore flow to range from moderate to locally breezy over the next few days. The central and southern part of the Guanacaste Peninsula will see a sea breeze develop for the mid to late morning and afternoon, while breaks in far north CR (near the Nica border) see light/variable to light offshore winds later in the afternoon.

Most of the region will see partly cloudy skies each day. Scattered showers/thunderstorms are possible and keep in mind that passing or nearby showers and thunderstorms can temporarily affect/change local wind conditions. 

EXTENDED FORECAST (Friday, May 20th, and beyond) 
Highlights: Another fun to mid size SW/SSW swell continues for back half of the week, trending down over the weekend. Modest Southern Hemi pulses going into the next week with potential for larger SW/SSW swell at end of May. 

South Pacific Swell: Fun SW swell (220-210) will holds going into Friday, while slowly fading some in the afternoon. Look for sets in the shoulder-head+ high range for top spots. Although this swell trends down through the weekend, expect locally fun surf throughout Central America. 

Beyond that, things start to slow down with a few overlapping Southern Hemi pulses going into next week. First, modest SSW swell (220-210) fills in over Sun/Mon, while a better looking SSW pulse starts to show the 25th-27th. Long range guidance points to more fun to potentially mid size SW/SSW swell around the last few days of the month, although we're low confidence on specific details this far out. Stay tuned.
