The Lowdown
G’day, Rusty here. Let’s talk about the waves ahead for Henrys. It’s a reef setup, and it’s consistent, so there’s always something to look at. The water’s sitting at a touch warmer than normal for this time of year, which is nice. Now, we’ve got a bit of a slow patch to start, but don't write it off.
The first real surf worth getting out for is Sunday the 16th. It’s not huge, but the swell’s holding at about 4ft from the southwest, with a 15-second period. The afternoon looks the pick with a light offshore wind, making for clean conditions. It’s not a monster, but it’s clean and fun. Monday the 17th keeps that SW swell going at around 4ft, and the afternoon is the go again – glassy, light offshore, just clean lines. These early days are about getting wet, not chasing size.
There’s a bit of a lull mid-week with the swell dropping. Thursday and Friday are smaller, around 2ft and 1ft. There’s some afternoon storm risk which messes with the surface, but the mornings hold some clean, small waves. If you're keen for a longboard with no stress, Friday morning is glassy, though it’s small.
Then we hit a flat spell. From Saturday the 22nd through to Thursday the 27th, the swell drops right out. It’s mostly under 2ft, and while there’s the odd clean window, there’s just not enough energy. The combined energy readings are weak, so it’s a paddle around, not a surf. This is a proper lull.
But hold on, because things kick back in for the final stretch. Friday the 28th is where it starts to get interesting. The swell pushes back to about 3ft in the morning, building to 3ft by the afternoon. The period jumps to 17-18 seconds – that’s a proper groundswell. And both sessions are glassy. The energy is back up, which is moderate. This is the standout of the whole window. It’s not huge, but it’s clean, lined up, and that reef will handle the long-period swell beautifully. This is a surf you don't want to miss.
Saturday the 29th follows right up. Morning has 4ft from the SW with a 16-second period and light offshore winds – another very good session. The energy is strong. After that, it fades a touch with more cross-onshore winds in the afternoons, but the morning of the 30th still has some 4ft swell, just a bit more crossed up.
So, the long story short: there’s a small, clean start, a dead week in the middle, and then a proper pulse of clean, long-period SW swell right at the end. The standouts are clearly the afternoon of Friday the 28th and the morning of Saturday the 29th. 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.
