The Lowdown
Alright, Rusty here, let’s have a look at what’s coming up for Henrys.
First up, we’ve got a bit of a slow start, but the waiting is worth it. The water temperature is sittin' about average for this time of year, so no surprises there.
The main action begins Wednesday morning, August 19, with a clean 3ft SW groundswell, a long 15-second period, and a light offshore breeze from the ENE. It’s a reef break, so those long-period lines will wrap in nicely – clean, consistent, and perfect for a quiet session. Combined energy is moderate (367). The wind stays light offshore through the afternoon, but there’s a risk of thunderstorms, so keep an eye on the sky.
Thursday and Friday are pretty small and messy – the swell drops to 2ft or less, and the wind shifts around. Not worth paddling out for, unless you just want to bob around.
Saturday morning, August 22, still small, but by Saturday afternoon a light SE breeze keeps things clean, with 2ft SW swell and 14-second period. The energy picks up a bit (256) and it’s rideable, but don’t expect much push.
Sunday morning, August 23, is a standout: 2ft SW groundswell but with a very long 19-second period, light offshore ENE breeze, totally clean. The energy is moderate (269) and the reef will turn those long-period lines into proper, well-shaped waves. A real treat if you’ve got the patience.
Through the next week, the swell stays small to moderate (2ft to 2ft), but there are a few good windows – especially Tuesday morning, August 25, with offshore conditions and a 2ft SW swell at 16 seconds. Clean and glassy in spots.
Now, here’s the big one. Friday morning, August 28 – hold onto your board. We’ve got a 2ft SW groundswell with a 19-second period, glassy conditions, and combined energy surging to 727 (strong). That’s a reef break dream setup. Perfect for experienced surfers looking for long, clean lines.
Then Saturday morning, August 29, the swell jumps to 5ft SW, period 16 seconds, combined energy over 1200 (very strong). Offshore cross-off breeze from the NNE keeps it clean. This is excellent but only for experienced surfers – it’s a solid step up in power. The reef will handle that long-period energy beautifully.
Sunday morning, August 30, holds similar size (5ft) but with a shorter period of 14 seconds, still clean and powerful. Another day for the crew who know what they’re doing.
Into the final days, the swell drops back a bit, but we get a glassy morning on Tuesday, September 1, with 4ft SW swell, 13-second period, combined energy 488 – good for a clean session. And Thursday morning, September 3, ends the run with a 3ft SW groundswell, 16-second period, glassy conditions, and energy at 813. That’s a very good note to finish on.
Overall, the best windows are August 23 morning for the clean, long-period magic, and August 28 morning for the glassy, powerful groundswell. August 29 and 30 mornings are for the experienced crew.
Stay stoked, and see you out there.

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.
