The Lowdown

Alright, let's be straight with you. The surf at Halfpoint/Fullpoint for the next couple of weeks is looking pretty grim. We're not chasing any quality waves here, that's for sure.

We start off on Tuesday the 15th with a tiny 0.5m easterly swell, but a 25 km/h NE cross-shore wind is just making it a complete mess. The energy is weak, only 128. It's a nothing day. Wednesday the 16th is much the same story: a little more size, but still cross-shore winds and a lumpy surface. You're not missing anything.

We get a bit more size on Thursday the 17th, with the swell coming in at 2.1m, but the period is a short 7 seconds. It's a close-range windswell that has no power or shape, and with a fresh 35 km/h cross-shore breeze, it's just churning. The energy is moderate at 604, but it's all for nothing.

The wind stays a constant problem. It's blowing from the ENE for almost the entire stretch, and it's always cross or cross-on. We see some decent size on Friday the 18th, around 1.0m, but it's mixed with a longer period SSW groundswell. The combined energy is strong, hitting 1058, but the fresh cross-onshore wind just kills it. It's a lumpy, bumpy mess out there.

The middle of the week brings more of the same. Bigger surf, 2.0m to 2.1m, but with that short 7-9 second period. The energy levels are moderate to strong, but the constant 35-40 km/h ENE wind keeps everything chopped up. On Thursday the 24th, we see some of the biggest surf of the period at 2.5m, but the wind is onshore, and the period is still short. There's a slight let-up in the wind Thursday afternoon with a light SSE breeze, but it's still onshore, and the conditions are only described as questionable.

The final days of the month don't offer any relief. We're still looking at that ENE wind, still cross or cross-on, and the surf remains small and disorganized. Most days are seeing swell around 0.8m to 0.9m with a 15-16 second period, but the strong winds just destroy any possibility of a clean wave. The energy is moderate at best, and it's not translating into anything surfable.

So, there it is. A long, frustrating 16 days ahead. The water is warm, at 27°, but that's the only thing going for it. For paddle surfing, this is a total loss. If you're into kiting, the strong cross-shore winds and bumpy conditions might be your thing. For the rest of us, it's a waiting game. These stretches of poor conditions do happen here, but the ocean always changes. We just have to hope for a shift in the wind and a proper long-period swell to show up.

Catch you next time,
Rusty

Information about the Halfpoint/Fullpoint Surf forecast

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