The Lowdown
Alright, this is Rusty, and I’m looking at the next 16 days for Rocky Point. Straight up, it’s a tough stretch. The forecast is pretty much a flat spell for the whole period, with just a tiny pulse of energy showing up way down the line.
Right now, the water here is sitting at a warm 80°, which is about normal for this time of year, so no surprises there.
The first suggestion of any real surf doesn't appear until Tuesday, August 18th. Before that, we’re looking at over a week of tiny, weak waves. From Tuesday the 11th all the way through Monday the 17th, the swell is barely a ripple, mostly around 0.7 ft to 1 ft, with poor conditions and a lot of cross-shore wind. There’s no point even paddling out for that.
Now, the one standout – and I mean the only one – is Tuesday, August 18th. The morning brings a bump in energy to 3 ft out of the NNW, with a combined energy reading of 135 (moderate). The wind is a clean cross-off from the east at 12 mph, so the surface will be clean. The swell is short period at 8 seconds, so it won’t have much grunt. The afternoon sees the energy climb to 209 (moderate) and the swell shifts to the NE, but it’s still short period. The forecast calls it marginal, which is honest. For a spot like Rocky Point, which is a very consistent reef break that loves a NW swell, this is the best we’re going to get. This is one for the intermediates; the size is manageable, and the clean wind is a big plus.
After that, Wednesday the 19th through the end of the forecast window drops right back into the doldrums, with swell heights under 2 ft and weak energy. The wind stays mostly cross-off or cross-shore, but there’s just no power in the water.
So, bottom line: if you’re keen, circle Tuesday the 18th of August. Morning or afternoon, the conditions will be clean, and we’ll have a little bit of wave to work with. For the rest of the 16 days... it’s a flat spell, plain and simple.
Rusty.

Information about the Rocky Point Surf forecast
The above surf forecast table for Rocky Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rocky Point can be found by selecting the local surf guide option on the grey menu. Our Rocky Point 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 (Rocky Point) 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 Rocky Point 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.
Rocky Point is 18 km (11 miles) from Wahiawa. If you plan a vacation in Oahu, look for hotels and other accommodation in Wahiawa. Wahiawa has rooms for a wide range of budgets as well as car hire and transport links.
