Updates in hr min s Forecast update imminent
Right, I’m looking at Hakalau and the news isn’t great. The next two weeks are mostly a washout for decent waves here.
Starting Tuesday morning, July 6th, we’ve got a waist-high swell at around 5ft (1.5m) out of the NE, but it’s getting blown out by a 15 km/h onshore breeze with rain showers. Water temp is about 80°, right around average for the time of year. The combined energy is weak, so not much power behind it. It’s just poor conditions right through.
The whole first week is rough. Swell stays between 5ft and 6ft (1.4m to 1.8m) but it’s short-period windswell (7-8 seconds) and the wind is mostly cross-onshore from the east or east-northeast. Tuesday afternoon on July 7th has the highest combined energy (623), but the wind is still onshore and the surf is marginal at best. No clean sessions.
Into the second week, Monday July 13th through to the weekend, the pattern doesn’t improve much. Swell dips down to around 5ft (1.4m) on average, period stays short, and the wind remains unfavorable – mostly onshore or cross-onshore from the east. The energy levels are moderate (peaking around 600), but the quality is just poor. It’s like the ocean is in a bad mood.
The best-looking window comes on Monday July 21st. The wind drops to a light breeze (10 km/h) from the east-northeast and it’s clear. But the swell is tiny – only 3ft (0.9m) in the morning, dropping to 2-2ft (0.5m) in the afternoon. That afternoon has a long-period 12-second swell from the east, which is rare, but the size is too small to consider. The combined energy is low (196). For a dedicated longboarder or a SUP, there might be a clean little wave at the river mouth, but it’s not a day to get excited about.
The standout? There isn’t one. The closest to a decent option is Saturday July 18th morning, with 6ft (1.7m) from the east, period 9 seconds, and combined energy of 507 – but it’s cross-onshore winds (20 km/h) and still called poor surf conditions. Not worth the drive.
So, Hakalau looks like a 16-day bummer. The wind and swell are never lining up to produce anything clean or with enough power. If those east winds hold, this might be a better spot for a kite session than a surf session. I’d keep the board in the car for this one.

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.
