The Lowdown
Alright, rustheads, Rusty here. Let’s get stuck into this run of surf that’s lining up for us at Henrys. This is a classic reef set-up, exposed to the west-northwest and it's picking up a consistent run of good quality, long-period groundswell from the southwest. The water’s sitting at a warm 86°F, which is a touch warmer than normal for this time of year – nice, you can leave the steamer at home.
We’ve got a solid week of waves kicking off from Monday afternoon, the 7th of September. It’s glassy as, with a light SSE breeze at just 3 mph, and the swell is a clean 4 ft from the southwest. The combined energy is a moderate 436, so there’s some good push in the water. This is a nice welcome back.
Tuesday morning, the 8th, really fires up. The wind goes offshore from the east at 9 mph, grooming a 2 ft groundswell. The period is a whopping 18 seconds, so the energy is up to a solid 625. Those long lines will wrap beautifully around the reef. The afternoon gets choppy, but the morning is the session to nail.
Wednesday the 9th and Thursday the 10th are the absolute standouts this week. Wednesday morning has the swell bumping to 3 ft with a 16-second period and a clean 16 mph cross-offshore wind. But Thursday morning, the 10th, is the pick of the bunch – that’s for the experienced crew. We’re looking at a 4 ft swell from the southwest, a 17-second period, and a light offshore breeze. The combined energy jumps to a strong 1124 – you’ll feel the grunt in every wave. This is proper, powerful reef surfing. Just be aware, the afternoons here get a cross-onshore breeze and risk of storms, so it’s a morning game.
Friday the 11th through the weekend keeps it going with clean, 3 to 4 ft surf and light offshore or cross-off winds. The energy stays in the moderate to strong range (468 to 725). Henrys is a consistent break, so it’ll be rewarding you even on the smaller days.
There’s a bit of a dip next week. Monday the 14th is small and average, with just 1 ft to 2 ft waves, but the period is a very long 19 seconds. The glassy morning might offer a sneaky longboard wave if you’re patient.
Then things start looking interesting again. Tuesday the 15th through Thursday the 17th see the energy creep back up, with 2 ft to 3 ft swells and clean offshore or glassy mornings. The periods stay long, between 14 and 18 seconds.
The real promise shows up further out. Look at the mornings of Saturday the 19th and Sunday the 20th – a 2 ft and 3 ft swell with a *very* long 19-second period, combined with zero wind, absolute glass. The energy on Sunday morning spikes to 717. Those are going to be some of the cleanest, longest lines you’ll see.
Then Monday the 21st of September keeps it going with a 3 ft, 18-second period swell and glassy conditions early. The afternoons get blown out, but those mornings over the second half of the run are a promising, long-range call.
So, bottom line: the standout is undeniably Thursday morning, the 10th of September for the best quality, biggest swell, and strongest energy. If you want the cleanest, glassiest long-period gems, mark your calendar for the mornings of Sunday the 20th and Monday the 21st of September. It’s a reef, so expect good shape but keep an eye on the crowd, as it’s *often* busy. Get on it.
Rusty.

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.
