Table - best surf conditions forecast for Hakalau over the next 16 days.
Alright folks, Rusty here. Let's take a look at what's on offer for the Hakalau stretch.
To be straight with you, the next 16 days are looking pretty grim for a proper paddle session. We’ve got a long stretch of nothing worthwhile on the horizon. The first half of the period is a write-off, and even when we get into the second week, the conditions are messy. The water temp is sitting around 80°, which is about average for this time of year, so no surprise there.
The only time this spot even gets close to being worth a look is on Monday, July 20th and the following Tuesday, July 21st. We see a pulse of energy come through, with the combined energy rating hitting a moderate 671 on the Monday afternoon, and even stronger at 802 on Tuesday morning. The swell is from the east, coming in at 3 ft to 4 ft, and the period jumps to a very long 17 seconds on Monday afternoon, dropping to 16 then 15 seconds on Tuesday. This is proper groundswell. Now, for a river mouth setup like Hakalau, a long period swell like this is a caveat—it can make the waves stand up and wall up nicely, but it can also make them a bit too straight and powerful. The wind is onshore the whole time, which is a bummer, keeping the surf pretty poor. The swell is small, so it's not a beginner hazard, but it won't be clean.
Sunday, July 19th, is flat with a 3 ft swell, and the rest of the 16 days is just a mix of rain showers, onshore winds, and tiny, weak swell. If you’re into kite surfing, that persistent onshore wind and moderate wave energy (397 on the 9th, 531 on the 12th) might look more interesting than a paddle. For the rest of us, it’s a blank run, which is a bit more normal for this area when the trade winds are cranking.
Honestly, there’s only one small window worth a mention, and even that is marginal. The best bet is to keep an eye on the Monday/Tuesday (July 20-21) window, but don't get your hopes up.
Rusty.

Information about the Hakalau Surf forecast
The above surf forecast table for Hakalau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hakalau can be found by selecting the local surf guide option on the grey menu. Our Hakalau 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 (Hakalau) 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 Hakalau 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.
Hakalau is 21 km (13 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.
