The Lowdown
Alright folks, Rusty here. Let’s get into what’s cooking for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a grim stretch. We’re looking at a long, frustrating run of onshore winds and poor surf quality. The first solid window we can even talk about is way out there, so settle in.
The water temp is sitting at 80°F right now, which is bang on average for this time of year – nothing to write home about in that department.
The only real window of hope we’ve got is a very brief one on the afternoon of Wednesday, the 29th of July at Kealia (Kauai). That afternoon, the wind is supposed to go glassy, and we’ll see a 8ft swell rolling in from the ENE. The period is a moderate 10 seconds, and the combined energy is moderate (983). The setup is a beach and reef, so with that glassy wind, it could clean up nicely for a few hours. The crowd factor is listed as "often," so expect company if you’re heading out. This is a short-lived window, but it’s the best we’ve got. For advanced surfers, that 8ft is a decent size, but it’s not out of control.
Before that, Tuesday the 28th has a bigger 7ft swell from the E with a 13-second period, but the wind is cross-on and gusty, making it choppy and marginal. Not worth the paddle. On Wednesday morning, the 29th, the swell is up to 10ft from the ENE (11-second period, strong energy at 1786), but with a cross-shore wind and a risk of storms, it’s a messy, powerful beast best left to the experts or the kite crew.
After that brief glassy window, it’s back to the same old story. From Thursday, the 30th of July, all the way through to Monday, the 10th of August, it’s a relentless grind of onshore ENE winds, with swell heights ranging from 4ft to 8ft but constant poor surf conditions. The energy values drop back into the weak to moderate range (172 to 1195), but the wind kills it every time. There’s a faint glimmer on the 4th of August with a 6ft swell from the ENE and a 12-second period, but again, the wind is onshore. It’s a frustrating pattern.
Honestly, if you’re not frothing over that Wednesday afternoon slot, this is a two-week period to save your energy and wait for a change. The consistent onshore flow is a tough beat. Forecasts can change, but right now, it’s looking like a long wait.
Rusty.

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