The Lowdown
Alright, Rusty here. Let’s break down what’s coming at Halfpoint/Fullpoint.
Water temp is 80°F—right about normal for this time of year. The big picture? There’s some swell, but the wind is going to be a headache for most of the next two weeks.
Monday the 27th kicks off with waves around 4 ft to 5 ft from the east, but a 19 mph cross-shore wind is making it lumpy and choppy. Not worth it. The combined energy is moderate (1184), but the wind ruins it.
Tuesday the 28th is the big winner. The morning brings solid 7 ft waves from the east, with a 13-second period. That’s proper groundswell, and the wind is a clean cross-offshore from the north-northeast at 19 mph. The combined energy jumps to a strong 2019. The afternoon gets even bigger, with 8 ft waves and more energy (2442). This is the best of the bunch—big, powerful, and clean. It’s a fairly consistent spot, so you’ll find waves. But at 8 ft, this is for experts only.
Wednesday the 29th tapers off. Morning waves are 6 ft from the east-northeast, with a light 3 mph onshore wind from the south-southeast. It’s clean enough, but the period drops to 10 seconds, and energy is moderate (866). The afternoon is smaller at 6 ft with a light breeze. Rideable, but nothing special.
From Thursday the 30th onward, the wind takes over. Strong east-northeast winds at 19–28 mph, blowing cross-shore or cross-onshore, create chop and lumpy conditions. The swell holds between 2 ft and 10 ft, but the quality is poor. Combined energy values are moderate to strong (434 to 1474), but the wind ruins it. This messy stretch runs from Thursday the 30th all the way to Sunday the 11th of August. That’s almost two weeks of windy, messy surf. The setup here is more interesting for kite surfing than paddle surfing.
On Tuesday the 4th of August, the period bumps up to 12 seconds, which is nice, but the wind is still strong. And on Tuesday the 11th of August, the morning has 6 ft waves from the east-northeast, but again, cross-onshore winds and a short period of 7 seconds kill it.
So, bottom line: Tuesday the 28th of July is the only real call. Get out there early for the clean, strong groundswell. After that, it’s a long wait for the wind to die down.
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.
