The Lowdown
Alright folks, Rusty here with a look at the surf ahead for the next couple of weeks. Let’s be straight with each other—it's a tough stretch for paddle surfing, but we'll walk through it.
The overall pattern shows a long run of mixed-up conditions. We start with some small, weak swell and poor surf, and while there's a bit more size around September 17th, the wind just won't cooperate. The best we get is a marginal call mid-month and again near the end of the window, but nothing that screams “drop everything and go.”
Honolii Beach Park is our only spot on the menu. It’s a river mouth, very consistent, and best for beginners. The optimum swell direction here is NE, which is what we’re seeing, but the wind is a constant problem. The water temp anomaly isn't recorded, so we'll just say it's about average for the time of year.
The first few days are a write-off. Saturday the 12th through Monday the 14th of September, we’ve got small swell around 0.8 to 1 ft, but the wind is onshore, and the wave energy is weak to moderate (194 to 259). The call is poor surf conditions – a no-go.
Tuesday the 15th and Wednesday the 16th stay poor. The swell bumps up to 6 ft on Wednesday morning, but it’s a short-period 7 seconds, with rain showers and a cross-onshore breeze. The energy jumps to a moderate 618, but it's messy and ugly. Not worth it.
Thursday the 17th of September is the closest we get to something rideable. We’ve got 8 ft of ENE swell, which is well over the 5 ft mark and into the zone where it’s too much for beginners. The period is 10 seconds, which is okay. The combined energy is strong (980 to 1070). But the wind is cross-onshore with risk of thunderstorms. It’s called a marginal surf forecast. For an experienced surfer who doesn’t mind the wind chop and some sketchy weather, there might be a few. But for most of us, it’s a pass. The swell is also pushing over 8 ft at times, which is expert-only territory.
From Friday the 18th through to Monday the 21st of September, we hover around 5 ft to 6 ft, still mostly poor with cross-onshore wind. There’s a slight improvement on Monday afternoon the 21st with offshore NE winds and 5 ft swell, but the energy is still just moderate (360) and it’s only a marginal call.
Tuesday the 22nd of September through to Thursday the 24th has similar size (5 ft to 6 ft) with light cross-onshore breeze. Thursday the 24th gets a mention with a moderate 607 to 656 energy from a longer-period 11-second ENE swell, but the wind is still cross or cross-onshore, keeping it in that marginal zone.
The final stretch from Friday the 25th to Sunday the 27th sees the swell drop back down to 3 ft to 5 ft, with energy falling off to weak levels (94). The wind stays light but mostly cross-onshore, so the poor conditions continue.
The standouts? Honestly, there aren't any true standouts. Thursday the 17th and possibly Thursday the 24th of September are the best on offer, but with the cross-onshore wind, thunderstorms, and size pushing into expert-only territory, it’s more about managing expectations than scoring barrels. The good news is this spot is very consistent, so it tends not to stay this poor forever—forecasts can change.
Given the consistent onshore flow and the beach-and-river setup, this actually looks more interesting for a kite surfer than a paddle surfer on most of these days.
Stay patient, gang.

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