Alright, Rusty here. Let’s have a look at what’s on the cards for your local stretch.

Honestly, I’m looking at this 16-day run and it’s a bit of a quiet one. We’re in for a real flat spell with no standout surf at all. The whole window is filled with weak, short-period windswell from the NE and ENE, mostly around 3 ft to 6 ft, with a period barely hitting 8 seconds – that’s just bumpy, crumbly stuff. The combined swell energy barely gets out of the two hundreds, peaking at 355 (moderate wave energy) on Monday the 6th of July afternoon, but even then the conditions are poor.

What’s really grinding my gears is the wind. For the entire first week, it’s onshore from the E or ENE at around 9 mph, sometimes 12 mph, keeping everything choppy and messy. There’s no stretch of clean, glassy conditions to look forward to. The surf breaks might be giving us something like 5 ft or 5 ft, but with that short period and onshore breeze, it’s just a bumpy, lumpy mess.

The only spot in the mix is Hakalau (Hawaii) – a river mouth setup that’s fairly consistent but exposed to the swell. The optimum swell direction is from the ENE, and we do get that at times, but the wind is wrong and the period is too short to shape anything decent. The wave comment across the whole forecast is “poor surf conditions,” and that says it all. Even on the few mornings that start clear, the onshore wind kicks up quick. Toward the second week, from around the 12th of July, the swell drops even further to about 3 ft to 4 ft, with cross-onshore winds making it choppy and uninviting. There’s nothing here that gets the heart racing.

If you’re really keen to get wet, the best you’ll get is maybe a small, weak wave at Hakalau on the 11th of July Saturday afternoon, when the wind drops to a light breeze from the NE at 6 mph and the sea state goes unknown – could be a little cleaner, but the swell’s only 3 ft from the ESE, not the optimum direction, and the energy is weak (217). Not a standout by any stretch.

So, unless you’re into a flat spell, I’d keep the board in the car and maybe check back in a week. Forecasts can change, but right now, it’s a proper lull.

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.
