The Lowdown
Alright folks, Rusty here. Let’s kick the tyres on this 16-day stretch for Rocky Point. We’ve got a long, slow start ahead of us, so don’t be in a rush to grab your board.
The first real sniff of anything worthwhile doesn’t show up until Monday the 7th of September. Before that, it’s a write-off. From now through the weekend, we’re looking at tiny, weak swells—mostly 1ft or less—with a messy cross-shore wind. The energy is laughable, barely climbing into double digits. It’s flat, it’s junky, and there’s nothing to get excited about. We’re talking a solid four-day gap of nothing.
Monday the 7th is where things finally change. The morning brings a jump to 6ft of swell out of the SW, with a long 14-second period. That’s proper groundswell energy, and the combined energy reading hits 1217 – that’s moderate, but it’s the first real pulse we’ve seen. The wind is offshore (ESE) and clean. This is a reef break, so that long-period SW groundswell is going to line up nicely. Size is intermediate-friendly, not too big, not too small. The afternoon builds even more, hitting 8ft from the SW with a 15-second period and a beefy 2646 energy reading. That’s getting up there – still manageable for the experienced crew, but the wind picks up to a fresh breeze. The water temp is sitting at 80°, which is bang on average for this time of year. Nothing weird there.
Tuesday the 8th is still in the mix, but it’s a step down. The morning has 6ft from the W with an 11-second period and 978 energy. The offshore wind is still clean, but the swell is already dropping. Afternoon drops to 4ft. It’s still surfable, but the quality is fading. The standout window is definitely Monday afternoon on the 7th – that’s the biggest, cleanest, most powerful window in the whole forecast. For a reef break like Rocky Point, that SW groundswell with a long period is a dream. Just be aware that it’s a very consistent spot, so the lineup will be busy. Crowds are likely.
From Wednesday the 9th onward, it’s back to small stuff. The energy drops right off, and we’re scraping around 2ft to 3ft for the rest of the run. The wind stays mostly cross or cross-off, but the swell just isn’t there. There are a couple of blips on the 15th of September with a 2ft SW swell and a very long 21-second period (408 energy), but it’s tiny and the wind is cross-shore, so don’t expect much. The 19th of September also has a 2ft SW groundswell with a 15-second period and 185 energy, but again, it’s small and the wind is just okay.
Bottom line: The only real day to circle on the calendar is Monday the 7th of September. The afternoon session is the pick of the bunch. After that, it’s a long wait for something that never really shows up.

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.
