The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Hakalau over the next couple of weeks.
Honestly, straight up, this outlook is a struggle. There's a long, grim stretch ahead for the river mouth. We've got a bit of energy, but the wind and conditions are just not friendly for a good paddle session for a while. The first real chance of something half-decent isn't until the very end of the first week, and even then it's marginal.
Starting out on Tuesday the 28th of July, there's a solid 8 ft of ENE swell (combined energy of 1897), but it's coming with a 9 mph cross-shore wind. It's going to be a messy, choppy affair and honestly, more of a kite-surfing kind of setup than a clean paddle surf. The water temp is sitting at 80°, which is pretty average for the time of year.
After that, it's a real desert. From Wednesday the 29th all the way through to Friday the 1st of August, it's just one poor forecast after another—cross-onshore winds, onshore winds, wind speeds picking up, and choppy conditions. The swell sizes vary from 4 ft up to 7 ft, but the quality is zero. You'd be wasting your time.
There's a slight glimmer on Sunday the 2nd of August and into Monday the 3rd. The swell drops a little, but the wind finally goes light and onshore from the ENE. Monday afternoon is the standout of the whole forecast. We get a 6 ft ENE swell with a long period of 13 seconds (groundswell energy of 1100) and a light breeze. That long period will shape up nicely at a river mouth, and the light wind should clean it up. It's not perfect, but it's the best we've got in this window. Just know the crowds can pop up here from time to time.
After that brief hope, it's back to the tough stuff. From Tuesday the 4th of August all the way to Wednesday the 12th of August, it's a long, bleak run. Mix of cross-onshore winds, sea breezes, and swell periods dropping back down to short 7 to 8 seconds. Swell sizes range from 3 ft to 5 ft, but the consistent wind chop and poor conditions means it's not worth paddling out. The longer you look, the more it looks like this region is just locked into a poor pattern.
So, bottom line: there's one session that's worth a look—Monday the 3rd of August—and the rest is a write-off. Keep an eye on the forecasts, because it might change, but right now, it's a tough call for Hakalau.

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.
