The Lowdown

Alright, folks, Rusty here. Let’s be straight with you. It’s a grim picture out there for the next two and a half weeks. We’re looking at a long stretch of onshore and cross-shore winds, and those are gonna chop up whatever swell we do get. If you’re a kiter, you might have some fun, but for us paddle surfers, this is a waiting game.

The surf window kicks off on Wednesday, August 5th, at Halfpoint/Fullpoint, but it’s a false start. We’ve got a small 3.6ft ENE swell, but a cross-shore NE wind at 15 mph is going to make it a bumpy, poor mess. The water temp is 80.2°, which is about normal for this time of year, so at least you won't need a hood.

Thursday and Friday are a write-off. The swell drops to a tiny 1.3ft, and even though it’s from the SSW with a long 14-second period, the cross-onshore and cross-shore winds will keep it ugly. It’s not worth paddling out for.

The weekend of August 8th and 9th sees a new ENE swell build, from 4.6ft up to 6.2ft. The period is short, only 7-8 seconds, which means it’s going to be weak and crumbly. Add a fresh cross-shore wind at 22 mph and you’ve got lumpy, messy conditions. The combined energy jumps from a moderate 360 to a strong 675, but it’s all for nothing with that wind.

Monday the 10th and Tuesday the 11th are still poor. The swell is all over the place, mixing old ENE energy with new SSW groundswell. Periods get longer, up to 14-16 seconds, but the waves stay small (2ft to 2.6ft) and the cross-shore breeze continues to wreck the surface. Still no dice.

Then things get interesting, but not in a good way for us. From Wednesday the 12th through Friday the 14th, the swell direction swings around to the south. The wave heights stay around 3.3ft to 3.9ft, but the period is long, 15 to 18 seconds. The combined energy is strong, peaking at 975 on Wednesday morning. However, the wind is still a fresh cross-shore, not offshore. Everything’s still bumpy.

The real deal arrives on Friday, August 14th. The swell jumps to 7.9ft, then 8.2ft from the ENE. But the period is short at 8 seconds, and the wind is a strong cross-shore at 25 mph. The combined energy is very strong, hitting over 1000, and it stays that way through the weekend and into early next week. This is big, powerful, and completely messy. For the most part, it’s too big for beginners, and even for experts, that wind is going to make it a battle. This isn't a surf session; it's a survival test.

The swell slowly eases from Monday the 17th into the following week, dropping back to the 6.6ft range by Wednesday the 19th, but the wind stays onshore. The energy remains strong to moderate, but the quality is consistently poor.

So, the long and short of it? There are no standout days here. The only real surf comes in the second week, around August 14th through the 19th, but the strong cross-shore winds and short period ENE swell will make it a messy, blown-out mess. For a spot like Halfpoint/Fullpoint that’s fairly consistent, this is a frustrating stretch. When the wind finally gives us a break, the swell will probably be gone. Hang loose, do some maintenance on your boards, and wait for better days. This run can’t last forever.

A general guide to surfing at Halfpoint/Fullpoint can be found by selecting the local surf guide option on the grey menu.

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 Halfpoint/Fullpoint 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.
