Table - best surf conditions forecast for Hakalau over the next 16 days.
Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead, and honestly, it’s a bit of a tough one for Hakalau. The overall pattern is dominated by onshore winds and choppy conditions, with very few windows of clean surf. The first few days are a write-off, and the real standout is a long way off.
The first recommendation shows up on Saturday the 12th, but it’s a real struggle. Sunday morning the 12th has a 5.2ft swell from the east, but it’s getting hammered by a 12 mph easterly wind. The combined energy is moderate (535), but the surf quality is poor. It’s just not worth paddling out. The wind stays onshore through the week, with a mix of rain showers and some clouds, making it a messy, choppy affair. The water temp is sitting at 79.5°, which is about average for this time of year.
We’ve got a long gap of nothing worth chasing really until we get into the second week. The onshore wind pattern just doesn’t let up. There’s a brief moment Monday afternoon the 20th where the swell period jumps way up to 17 seconds, sending a long-period groundswell at 3.9ft from the east. The combined energy spikes to 1036, which is strong. This is a very long-period swell, so it’s going to be better suited for a point or reef break, not so much a river mouth. The wind is light from the ENE at 6 mph, keeping it clean. This is the standout. It’s a week and a half away, so it’s a promising long-range call, but not set in stone. The following days on the 21st see the energy drop but still with long periods, though the wind gets a bit cross-onshore.
After that, things settle back into smaller, wind-affected surf. The swell drops back to the 3.9ft to 4.6ft range from the east-northeast, with periods of 7 seconds, and the wind is light onshore again. Not much to write home about. The best bet, if you’re patient, is that Monday afternoon the 20th wave. It’s the only time the stars almost align.

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.
