The Lowdown
Alright, let’s size up Halawa. It’s a reef and river setup, fairly consistent, and it loves a clean NNW swell. Water temp is about 79°F, which is right where it should be for this time of year.
For the first couple of weeks, it’s a real downer. From Thursday, July 16th, all the way through to the morning of Wednesday, July 29th, it’s basically a dead zone. The wind is a constant cross-shore, mostly from the east, and it’s got enough kick to keep the surface all lumpy and messed up. The swell is all over the place, short-period junk from the east, and the combined energy is weak to moderate, with numbers like 356 (moderate) and 279 (weak) – nothing that’s gonna get the stoke up.
There’s a bit of a tease on Saturday, July 18th, in the afternoon, when the swell jumps to 7ft from the ENE, with some moderate energy (530), but it’s still cross-shore and lumpy, so it’s a no-go. The same story repeats for days: the swell size gets up to 8ft from the ENE on Sunday, July 26th, with energy hitting 949 (strong), but it’s cross-onshore and messy. For a spot that needs a clean offshore, this is all just heartbreak.
The only glimmer in this whole 16-day window is on Wednesday, July 29th. The morning shows a 5ft groundswell from the ENE, with a long period of 12 seconds and a solid 826 (strong) combined energy. The wind is a gentle cross-shore, which is the best we’ve seen. It’s still only a 1 out of 10 and called “marginal,” so it’s not a standout. The afternoon drops to 5ft with a period of 12 seconds and energy of 679 (moderate), but the wind picks up to a moderate cross-shore, bringing a little chop.
So, there’s no true standout in this window. The only day that looks even remotely worth a look is Wednesday, July 29th, but it’s a gamble. The long period means the waves will have some punch, but on a reef, that can be a bit dicey if the tide isn’t right. The break is inconsistent, and with the conditions, it’s a real “maybe” at best. For the rest of the time, the wind is just too on it to make anything of the swell that’s coming through. It’s a dry spell, mate.

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.
