The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table for the next couple of weeks. Honestly, it's a pretty grim stretch for Honolii Beach Park. There’s nothing worth paddling out for right now, and we’re looking at a long, quiet run.
The opening days are a total write-off. Through the middle of the month, we’ve got tiny swell, poor surf conditions, and winds that just aren't playing ball. That combined energy is weak, sitting around 155 to 185 (combined energy of all swells directed here), which tells you there’s barely a pulse. The water temperature anomaly is about average for this time of year, so nothing weird there, but it doesn't matter when there's no waves.
We do see a bump of energy building toward the 16th of September, with swell height creeping up to 4 ft from the E and ENE, and combined energy jumping into the moderate range (536 to 587). But the wind is onshore or cross-onshore, and the period is short at 10 seconds, so it’s still going to be messy and poor. The 17th sees a bit more size – 8 ft from the ENE – but that’s getting into expert-only territory for a river mouth, and with a risk of thunderstorms and cross winds, it's marginal at best. The combined energy hits 1000 (combined energy of all swells directed here), but the conditions just aren't there.
From the 18th through to the end of the month, we're stuck in a pattern of 5 ft to 8 ft ENE/E swell, but it’s consistently undermined by onshore or cross-onshore winds. Periods are short, mostly 8 to 10 seconds, so the waves will be weak and crumbly. The combined energy varies from moderate to strong (370 to 1086), but the wind keeps it all chopped up. A few mornings like the 21st and 26th have light offshore winds, but the swell quality is still questionable, and the score is never better than marginal. The 26th morning shows 7 ft from the E with a light offshore, but again, it’s a marginal call with questionable tide conditions.
Bottom line: there’s no standout window here. The whole 16-day stretch is plagued by poor conditions, and the consistent onshore wind kills any chance of clean waves. The best you could hope for is a quick look on the 17th or 26th morning, but even then, it’s not worth getting excited about. Sometimes the coast just goes quiet, and this is one of those times. Forecasts can change, but right now, I’d save the wax.
Rusty.

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.
Honolii Beach Park is 4 km (2 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
