The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve scanned the charts for the next couple of weeks, and I gotta tell ya, it’s looking pretty grim for a proper paddle. The swell is there at times, but the wind is just gonna mess it all up. We’re looking at a long stretch of onshore and cross-onshore junk that’s going to leave things chopped up and messy.
The first few days are a write-off. Saturday the 5th has a bit of size, around 8ft, but that east wind and rainy conditions are going to make it a messy battle. The following days through to the 11th see the wind staying cross-on from the east and southeast, with the swell dropping and bumping around. It’s not going to be worth your time.
There is a gap in any decent surf for the best part of a week. But don't lose hope. Around the 13th, things might get a little interesting. There’s a window on Sunday afternoon where the wind switches to a light cross-shore from the north and the swell bumps back up to 7ft from the east. The energy is moderate, and it'll be the first time in a while it might actually line up a bit. It's a river mouth, so a period of 8 seconds is a bit short and could make it a bit soft, but it’s the best we’ve got, so keep an eye on it.
After that, the trade winds are back and we’re back to the choppy, messy stuff. There's another tease on Thursday the 17th afternoon, with a similar size bump to 7ft, but that onshore wind is going to be a problem again. Even the last few days of the period show a bunch of energy around 5ft to 8ft, but the wind looks like it just won't give us a break. This whole stretch is looking like hard work. It might be more interesting for the kite crowd than us paddle surfers.
The water’s warm, sitting around 81° for Hakalau, which is pretty much normal for this time of year, so at least you won't need a thick suit.
Just keep checking back. The surf’s not gone forever, it’s just taking a rough patch.
Rusty out.

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.
