The Lowdown
Alright, let’s get into it.
For the next couple of weeks, Halawa is mostly going to be a frustrating one. We’re looking at a lot of cross-shore breeze messing up what could be decent sized swell. It’s not going to be a total loss, but you gotta pick your moments.
The first real action we see kicks off on Wednesday the 16th. The swell jumps up to 5ft in the afternoon, coming from the ENE with a 10-second period. It's a bump in energy, but that cross-onshore wind is going to chop it up. Then Thursday the 17th sees the biggest push of the early run – 8ft from the ENE in the morning. That’s solid, and there’s a lot of energy in the water (775 combined). But again, that cross-shore wind keeps the quality down and makes it look like a mess. It’s powerful, but not clean. The swell is below the 8ft mark, so it’s not just for experts, but that chop will test your patience.
After that, it flatlines for a bit. We go from Friday the 18th all the way through to the morning of Saturday the 26th with barely a ripple. For almost a week, it's near-flat, with the swell dropping to 0.3ft. The wind is fresh and cross-shore the whole time, so you can forget about riding anything. It’s a real frustrating gap.
Then we see the swell start to build again on Saturday the 26th. The morning has 6ft from the ENE, but it’s only a 7-second period. That’s short-period, wind swell. There’s moderate energy (325), but it’s lumpy and rough. It stays like that through Sunday the 27th, with waves around 6ft, and it’s still messy with that cross-shore breeze. The period is even shorter, down to 6 seconds, which isn't great.
Monday the 28th keeps the size around 7ft from the ENE, still with a short period. The energy is in that moderate range (599), but it’s not what I’d call good surfing. The conditions are still poor.
Now, there is one window that stands out. Tuesday the 29th. The morning still has that 7ft of ENE swell, but the wind finally lets up a bit to a light breeze. It’s a start. But the real gem is Tuesday afternoon. The swell size is still solid at 7ft from the ENE, and we finally get a cross-offshore wind. That’s the cleanest we’ve seen it. The water is going to be clean, and this will be the standout session of the whole run. Expect very good surf conditions then. That’s the one to make time for. The energy is still moderate (670), but the shape and the lack of chop will make all the difference.
Keep in mind, a lot of these swells are from the ENE and NE, but Halawa's optimum is from the NNW. So we’re not getting the ideal direction. That’s a bit of a hamper.
The water temp is 81°, which is pretty much average for this time of year. Nothing crazy there.
So, bottom line: Don’t get too excited until Tuesday afternoon. That’s your best bet. Before that, it’s mostly a write-off. And remember, a break like Halawa that’s a reef/river setup, those longer period swells can sometimes be better, but we're not getting those here. It's all about that Tuesday afternoon window.
Rusty out.

Information about the Halawa Surf forecast
The above surf forecast table for Halawa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Halawa can be found by selecting the local surf guide option on the grey menu. Our Halawa 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 (Halawa) 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 Halawa 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.
