The Lowdown
Alright, Rusty here, let’s talk about what’s cookin’ for the next couple of weeks. This is one of those rare windows where the stars line up right at the start, so don’t sleep on it.
The first real action hits on Wednesday, July 29th. We’ve got a clean, glassy morning at Kewalos, a reef setup that loves a good SSE direction. Expect head-high plus waves, around 6 ft, pushing in with moderate energy (909). The wind is dead calm, glass, and the water temp is sitting at 80°, which is pretty much normal for this time of year. This is the standout of the early window. The afternoon stays glassy with a fun, slightly smaller 5 ft. The period is around 9-10 seconds – a solid combo swell.
From Thursday, July 30th, things get a bit tricky. Winds swing around to the ENE and pick up, keeping the surf a little bumpy or cross. The swell stays rideable, but the quality drops. By Friday, July 31st, the wind is on it pretty strong (up to 25 mph), making it a bit of a messy grind even with chest-high 6 ft waves. We go through a stretch where a strong ENE trades hammer the coast, and while there’s plenty of swell – even pushing into the 8 ft to 10 ft range by Saturday, August 1st – the conditions are just blown out. That’s a long stretch of clean but wind-affected surf, which is only really for the experienced crew.
We get a little breather on Tuesday, August 4th. The trades ease back and we get some long-period groundswell (11-12 seconds) rolling in at about 5 ft to 5 ft. The wind is a light cross-off, which should clean things up nicely. Energy is moderate (735), and it’ll be worth a paddle.
After that, the energy fades and the period drops. By the second week of August, the size is down, and the swell direction swings to the SSW and S with longer period, but the trades are back in full force, making things look more interesting for the kite crowd than for a standard surfer. The waves are small and messy.
For a solid, clean session: Wednesday morning, July 29th, at Kewalos. 6 ft, glassy, and perfect for a reef break. That’s your stand-out window in the whole 16-day run. The rest is a waiting game for the wind to let up.
Rusty.

Information about the Kewalos Surf forecast
The above surf forecast table for Kewalos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kewalos can be found by selecting the local surf guide option on the grey menu. Our Kewalos 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 (Kewalos) 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 Kewalos 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.
