Effective Friday afternoon
                HIGHLIGHTS  

• Modest South-SSW swell next few days
• Second half of June looking good

Wind/Weather: Most of the Costa Rican coastline will see a diurnal wind pattern for the next several days; calm to light/variable to locally light+ to moderate offshore wind through the early to mid mornings (depending on precise location), before a moderate onshore seabreeze gradually develops over the late morning/afternoons (a little stronger for some areas, lighter for others).

Most of the region will see partly cloudy skies each day. Possible isolated showers/thunderstorms here and there, as it is the tropics. Expect more showers/thunderstorms right now further offshore. Keep in mind that passing or nearby showers and thunderstorms can temporarily affect/change local wind conditions.

EXTENDED FORECAST: (Wednesday, June 14th, and beyond)   
           
Swell/Surf: The South Pacific is firing back up with storm activity and looking to cook for at least the next 7 days or so. And these storms are developing everywhere from under New Zealand to just offshore from South America. As a result, a series of good swells ranging from SW to South are stacking up for Central America for the second half of June.

For the SW Pacific; we just had a large/strong storm slide out from under New Zealand, and another one is projected to soon follow. For the SE Pacific; a smaller but still rather intense low is currently developing out to the west of Chile, with a larger/stronger storm projected to develop just off the southern tip of South America early next week. This southern tip storm is looking to setup a strong/well aimed fetch that may also push toward Central America, all good things to send a solid swell.

As a result, we're looking for a good size and consistent run of overlapping SW-South swells (ranging everywhere from 220-180°) to move in on the weekend of the 17th-18th, then hold fairly steady through the 21st. Many spots will be seeing at least head-overhead surf during this event, while standouts produce some well overhead sets. Occasional double overhead+ waves will show for select magnets. This run will gradually back down from the 22nd and thereafter. Stay tuned for the updates on Mon/Wed/Fri, as this event is still evolving.
