The Lowdown
G’day, crew. Rusty here, and I’ve been poring over the charts for our local slab. It’s a bit of a mixed bag, but there’s a couple of real gems if you’re patient.
The standout is clearly Henrys (a reef, exposed to the swell) on the morning of Friday the 14th. We’ve got a solid 4ft SW groundswell with a very long 18-second period pushing in, and the combined energy is sitting at a solid 919 (moderate). The wind is a clean offshore ENE breeze at 12 mph, so the face will be glassy and lined up. The water temp is 86°, which is a touch warmer than normal for this time of year, so maybe leave the steamer at home. Early Friday morning is the pick of the whole 16-day window—clean, consistent, and a classic reef setup.
Friday afternoon still holds decent 4ft SW swell and the energy jumps to 1132 (strong), but the wind swings to a light SE cross-off, so it’ll still be rideable. Saturday the 15th drops off a bit; the swell is up to 5ft SW but the wind is a fresh 19 mph cross-off which makes it choppy, and the scores are average. The morning of Sunday the 16th has 4ft SW swell but the energy drops to 606 (moderate) and the wind is a moderate cross-off, so it’s a bit average.
We’ve got a long gap of ordinary surf from Saturday the 15th through to the 20th, with a few afternoons ruined by onshore westerlies and risk of thunderstorms—pretty poor paddle conditions. The 3ft swell on Tuesday the 18th afternoon is a write-off with onshore W wind at 6 mph. The 3ft swell on Wednesday the 19th morning is clean with an offshore ENE breeze, so that’s a small window, but the afternoon is again stormy.
The second week starts to come back to life. From the 21st the swell really drops, with 2ft on the Friday morning, energy just 124 (weak), so don’t get too excited. A few mornings of 2–2ft SW swell with offshore ENE winds are clean but tiny. The real spike comes on Friday the 28th of August: morning surf with 3ft SW groundswell at 17 seconds, clean offshore ENE breeze at 6 mph, and the energy jumps to 713 (moderate). That’s a promising late-run standout, but it’s a ways out so keep an eye on the long-range charts.
Saturday the 29th of August morning also looks good, with 4ft SW swell, 16-second period, 762 (moderate) energy, and a gentle offshore ENE breeze at 9 mph. Both Friday and Saturday mornings in that last week of the month are worth circling on the calendar.
Overall, the best bet is this Friday morning, August 14th, at Henrys. Long period, clean, and the reef will handle it beautifully. If you can’t make that, keep an eye on the 28th/29th for a resurgence.

Information about the Henrys Surf forecast
The above surf forecast table for Henrys provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Henrys can be found by selecting the local surf guide option on the grey menu. Our Henrys surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Henrys) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Henrys may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Henrys is 47 km (29 miles) from Nicoya. If you plan a holiday in Guanacaste, look for hotels and other accommodation in Nicoya. Nicoya has rooms for a wide range of budgets as well as car hire and transport links.
