CRNW Forecast & Report of 2017-0620 for Sun-Tue

Sunday, June 18, 2017: Travel Day

Spent 5 days before the trip in FL for a surprise 40th birthday party for Brett this past Saturday. So I flew SWA from Orlando to Houston to Liberia. For some reason by TSA PreCheck wasn't automatically on my ticket so had to square that away at the counter. In Houston, I was called to the gate counter because my passport info wasn't in the system. At least the board bag made it all the way, no charge. Brett and buddy's flight from MIA-LIR was an hour late but that synced up well with my ahead of schedule flight.

Surfed a really mixed up Northside Rock area yesterday, 5-8 ft. Short period W swell was a pain in the ass but Tim and I did fine, after a slow start my session was very good and Tim was happy. The other two guys are on shortboards didn't fare as well. Think the surf was a little too big and takeoffs a bit too steep for them. Lot of current all over, I never really stopped paddling. My groins were aching this morning.

 

Tuesday, June 20, 2017

This morning Tim and I paddled out too early, tide was still too low and there was no channel, waves breaking all over. After an hour I went in and Tim about a half hour later. The other two had passed on it, said they might go to Avellanas. As we were leaving they were walking down the road to check the surf and we told them ot hit it as the higher tide had organized the surf more. Tim joined them, I bailed to spend some time with the butterflies and some coffee. I am hopeful about tomorrow and hoping not a rain-filled day.

Rainy season came early this year, late April, and last week there was a ton of rain. Rain showers the day we arrived on Sunday but only a brief shower for an hour mid-morning yesterday. Fair amount of blue in the skies this morning. Tons of butterflies sucking up the nectar in the flowering plants in front of our southside casita, a couple of hummingbirds earlier, and a small flock of 20 or so parakeets flying by and chirping away. 

 

We miss you regular summer boys (Terry & David) not being here!!!

 

Continuing apparent discrepancies between ByWeather and SL. Don't they get their raw data from the same source? Once shows 17 sec periodicities the next 3 days and the other tops out at 15 sec.

North Costa Rica Forecast effective Monday afternoon. Forecast Outlook:
TUESDAY: Solid blend of SW/SSW and S swell tops out/holds. Better exposures are running head high+ to a few feet overhead with focal points hitting the double overhead range on sets. Localized windswell blends in, adding some jumble.

WEDNESDAY: Solid blend of SW/SSW and S swell continues. Exposures are running head high-overhead+, focal points continuing to go well overhead at times. Localized windswell blends in, adding some jumble.
WEATHER/WIND: Light/variable winds prevail early each day, trending onshore through the mornings before moderate onshore flow develops through the afternoons. Winds ease in the evenings. Showers/thunderstorms are likely, with a pattern more reminiscent of the rainy season in place. Keep in mind, passing or nearby showers and thunderstorms can temporarily affect/change local wind conditions.

 

NOTE - Some localized Westerly windswell blends in through the middle of the week. While not adding any additional size, expect surf to be fairly jumbled on the whole.

Wind/Weather: Most areas along the Costa Rican coastline see variable to light onshore winds in the mornings through the middle of the week. Light to locally moderate onshore flow develops in the afternoons, before winds ease in the evenings.

Showers/thunderstorms are likely with a pattern more reminiscent of the rainy season in place. Keep in mind, passing or nearby showers and thunderstorms can temporarily affect/change local wind conditions. 

EXTENDED FORECAST: (Thursday, June 22nd, and beyond)                  

Swell/Surf: Decent size continues Thursday, better exposures in the shoulder-head high+ range as focal points continue to pull in some sets running up to 2'+ overhead. The gradual trend towards smaller surf continues Friday, size dropping off more rapidly as we head through the coming weekend.

Looking a little slower to start next week, as it appears the South Pacific will take a bit of a breather. By the end of that week we'll be watching the potential for a fresh run of S swell from another low slated to deepen just off the coast of South America. More potential SSW/S swell may follow early July. Stay tuned.

Winds/Weather: Looking more favorable through the end of the week and into the weekend as a more typical diurnal pattern shows potential to return.

CRNW Forecast of 2017-0617, Sat (The Day Before The Day Before)

Guess it is still the day before the day before as first fins in the water will be Monday and tomorrow is a travel day (tides wrong on our late afternoon arrival).

Buoyweather only shows the primary swell for each hourly entry but you can see around 6/21/17 that there two co-dominant swells. The longer period dominant swell is good sized with periodicity of 16-17 sec in the table below. For some reason this doesn't always show up in the preeminent surf forecasting service--which also happends to own Buoyweather--so one can scratch their head wondering,"Isn't data, data?" 

One thing seems certain: there will be waves and the nature of the waves will vary widely over the course of two weeks with nearly daily variations (as reflected in the color table below).
