The Lowdown
G’day, Rusty here. Let’s break down the next couple of weeks at Henrys (Big Island). The water’s running about 86°F, which is a touch warmer than usual for this time of year.
We kick off Wednesday the 9th with a clean 3ft southwest swell, long 16-second period, and light offshore east winds. Water’s glassy, real nice. Energy is moderate at 564. Good way to start.
Thursday morning the 10th, the swell bumps up to 4ft with a 17-second period, and the energy jumps to 1163. The wind is cross-off from the ENE, so it’s clean, but it’s got some punch. That’s a solid morning if you’re up for it. By the afternoon, the wind swings south and it gets messy, so bail early.
Friday the 11th holds around 4ft with a 16-second period. Mornings are clean with a light NE cross-off, and the afternoon has a light SSE breeze – both sessions look good. Energy is still solid.
Saturday the 12th drops to 3ft, and the period shortens to 14 seconds. Morning is fine with light ENE winds, but the afternoon brings storm risk and onshore wind. It’s a morning-only wave.
We hit a flat patch from Sunday the 13th and Monday the 14th – down to 2ft and 2ft. Not much happening, and afternoons are getting chopped up. Not worth it.
Tuesday the 15th sees a return to 3ft with a 15-second period, and the morning is clean with light winds. Wednesday the 16th and Thursday the 17th both hold around 3ft with good offshore east winds in the morning. Those are good fun.
Now, the real standout is Sunday the 20th of September. Swell is back up to 3ft, but the period is a glorious 19 seconds, and the energy is pumping at 946. Light SSE cross-off wind in the morning will have it glassy on the reef. That’s the best wave of the whole run.
Monday the 21st is also very good – 3ft at 18 seconds with 833 energy and light winds in the morning. Another one to get out for.
After that, it fades. From the 22nd through the 24th, the period drops, the wind turns onshore and stormy, and the surf gets junk. Not worth the paddle.
So, bottom line: the 20th and 21st are your days. Mornings are the go in the second week, and the afternoons are mostly a waste. It’s not massive, but there’s enough push and length in the swell to make it fun.
Rusty out.

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.
