The Lowdown
Alright, Rusty here again. Let’s break this down in feet and miles per hour for those who think that way.
The next couple of weeks are going to test your patience if you’re surfing around here. We don’t see a real recommendation until Sunday, the 23rd of August, and even that’s a stretch. After that, there’s a massive gap with almost no rideable waves from Monday the 25th through the end of the month and into early September. Plan on a solid week and a half with nothing worth paddling for.
Our only real option is Hapuna, a sandbar break that’s fairly consistent but best for intermediate surfers. The water temp is around 82°F, which is about 2°F warmer than usual – nothing crazy, but a little toastier than average for late August.
On Sunday the 23rd afternoon, we get a tiny pulse: 1ft from the WNW with an 11-second period. The combined energy is a weak 77 – just a small, dribbly wave. Wind is cross-offshore from the NE at 9 mph, keeping it clean. It’s not going to blow anyone away, but if you’re desperate for a session, this is your best shot. Expect a few other folks out – crowds can pop up sometimes.
Monday the 24th is worse. A 0.7ft SSW swell with an onshore breeze in the morning – just ugly. Afternoon goes glassy, but the wave is barely 0.3ft. More of a lake than an ocean.
From Tuesday the 25th all the way through the end of the month, every entry says "poor surf." The swell never breaks 1ft, coming from the SSW with periods between 13 and 18 seconds – that’s long-period groundswell, but it’s so tiny it never shows up. Combined energy stays below 50 after the 23rd – weak stuff. Winds are often light and cross-offshore or glassy, so conditions look clean, but there’s nothing to ride.
Into early September, it’s the same story. A couple of 0.7ft pulses from the SSW, and a 1ft bump from the W on the 7th with a 16-second period (combined energy 45). Still just knee-high mush at best. Glassy conditions on a few afternoons, but the swell is flat.
There are no standouts. The entire 16-day window is a bust for decent surf. This kind of dry spell is normal for the area – the breaks just don’t have the exposure to push through when the swell is this small. If you’ve got a kite, the clean offshore breezes might make for some fun on the flat days, but for a surfboard, it’s time for a rest.
The forecasts can change – it doesn’t stay this quiet forever.
Rusty.

Information about the Hapuna Surf forecast
The above surf forecast table for Hapuna provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hapuna can be found by selecting the local surf guide option on the grey menu. Our Hapuna 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 (Hapuna) 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 Hapuna 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.
Hapuna is 84 km (52 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.
