The Lowdown
Alright, let’s talk waves. We’ve got a bit of a dry spell to start, so don’t rush out there. The first real chance to get wet is on the 9th, but the true winner is Thursday the 10th. We’re looking at swell around 4ft from the SW with a long period and a ton of energy. The morning is going to be clean with offshore winds – that’s your golden ticket. Henrys (Big Island) is a reef, so it’ll suit this kind of long-period swell perfectly. Water temp is running a bit warmer than average, nothing too wild.
The days after have some fun waves, with similar southwest groundswell but slightly smaller. Mornings are your friend, as the afternoons often get a bit bumpy. There’s another push of energy around the 15th and 16th, but it’s not quite as strong.
Into the second week, it gets trickier. The mornings are still offering clean-ish surf, but the wind turns more onshore in the afternoons. There’s a bigger, short-period swell on Saturday the 19th, but with that short period, it’s going to be all over the place – that’s one for the experts only.
The end of the run, from the 22nd onward, looks poor, with more onshore slop and weaker swell. The 20th and 21st still have some juice but the wind will ruin it. So, keep your eyes on the 10th and 11th – that’s the best we’ve got, hands down.

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.
