The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
To be straight with you, the next couple of weeks are looking pretty bleak for a proper surf. The only spot in the mix is Browns, a reef break, and it’s almost a complete write-off for the first ten days. We’re talking about a stretch from Wednesday, August 5th, right through to August 15th where the conditions are just poor. The swell is tiny, mostly around 0.7ft to 1.0ft, and the combined wave energy is next to nothing, barely cracking 28 (weak energy) at best. It’s a lot of waiting for nothing.
The period from the 12th to the 14th of August sees a little more life, with swell creeping up to 1ft to 2ft from the WNW and W, with periods around 13 to 14 seconds. The combined energy hits 70 (weak energy) on the 13th and then 92 (weak energy) on the 14th. But the wind is a problem – mostly cross or cross-on, keeping things messy. Friday afternoon the 14th does have a glassy moment, but the swell is just too small to get excited about.
Now, there is a glimmer. The standout here is the period around the 15th and 16th of August. We’ve got a nice little pulse of groundswell arriving. On Saturday the 15th, the swell picks up to 2ft from the W with a very long 15 second period, and the combined energy jumps to 166 (moderate energy). The wind is light cross-shore, which should keep it reasonably clean. This is the best-looking window. Sunday the 16th keeps that 2ft W swell, though the period drops a touch to 14 seconds, and energy stays solid at 161 (moderate energy). The wind is light cross-shore again. For a break that’s a consistent reef, and with the swell direction (W) matching the optimum direction (WNW) pretty closely, this is where you want to be. It’s still small, but it’s the most promising we’ve got, and it’ll be clean. Just a heads up, crowds are possible here.
After that, Monday the 17th of August offers a 1 out of 10 rating with surfable but very ordinary conditions. The swell holds at 2ft from the W, but the wind goes cross-off, which is a nice change. Still, it’s not a classic.
So, the call is simple: the first week and a half is a skip. The real chance is that Saturday the 15th and Sunday the 16th. It’s not going to be huge, but for a long-period, clean little reef wave, it’s your best shot. Don’t expect much else.
Rusty.

Information about the Browns Surf forecast
The above surf forecast table for Browns provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Browns can be found by selecting the local surf guide option on the grey menu. Our Browns 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 (Browns) 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 Browns 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.
Browns is 86 km (53 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
