The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this stretch we’re looking at is a real mixed bag, and honestly, it’s mostly a waiting game. The next couple of weeks are going to test your patience more than your paddle stamina.
Right off the bat, the surf is just messy. We’ve got a solid amount of energy in the water, somewhere in the moderate range (1155) early on Sunday, but it’s coming from the ENE with a short, 9-second period. That’s all windswell chop, and with a 25 km/h onshore breeze, it’s going to be a washing machine out there. Forget about clean lines; it’s just bumpy and messy. This poor quality is the story for the next week and a half. The swell does dip down a bit mid-week, but it’s constantly showing "poor surf conditions." We’re talking all onshore winds, short periods, and just a general lack of any push or shape.
The energy does build back up around the 8th and 9th, hitting the moderate range again (around 293-301), but it’s still windswell with a 7-second period. It’s more of the same choppy, disorganized stuff. Kealia (Maui) is an exposed spot, so it’s catching everything, but that’s not doing us any favors here. The water temp, by the way, is about normal for this time of year.
Now, looking further out, things finally start to get interesting. Around the 17th, we see the swell starting to push up again, hitting 2.1m. The energy jumps back into the moderate range (514). It’s still coming from the E, and the period is still short at 8 seconds, which is far from ideal. The wind is also looking cross-onshore, which is a real buzzkill. This is a bigger swell, but it’s not necessarily a better one. It’s still looking like a messy, power-chop situation. For an advanced crew at Kealia, it could be a punchy session, but it’s not a clean, classic day.
Honestly, there is no standout day in this whole forecast. There’s no "go-time" moment where it all lines up. The whole 16-day window is just a grind of onshore wind and short-period swell. There are no real gems to highlight, just varying degrees of poor to average conditions. I’d say keep your board waxed, but maybe keep an eye on the long-range models. With a spot like Kealia, it can turn on quickly when the conditions line up, but this isn't that window.
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.
