The Lowdown
Alright, Rusty here. Let's get into it.
First up, I gotta be straight with you—this is a tough one. We're looking at a 16-day window for Goat Island Reef, and honestly, it's a real struggle. The spot is a sheltered, beginner-friendly beach and reef set-up that rarely breaks, and that's exactly what we're seeing. The first week is a total write-off, with next to nothing on offer. We're talking flat, weak swells with tiny energy readings and mostly cross or onshore winds. It's a long, boring gap for surfers.
The only glimmer of hope, and I mean the only one, shows up around Tuesday the 11th of August. That morning we get a pulse of 6ft swell from the north, with a 9-second period, producing moderate wave energy. The wind is cross-off from the ESE, which is decent, and the conditions are clean. It's a marginal surf forecast, but it's the best we'll see. The afternoon drops a bit to 5ft, still clean. Even then, it's not great, but for this spot, it's the standout.
Other than that, the rest of the run is mostly poor. There's a whiff of something on Friday the 14th of August morning with a 5ft NW swell and offshore wind, but it's short period and low energy. The rest is tiny, weak, or onshore. The water temp is sitting at 59°F, which is about average for the time of year, but you won't be in the water much anyway.
So, bottom line: if you're desperate, the 11th of August is your best bet. Otherwise, this is a blank run. For an area like this, it's not unusual for it to go quiet for a stretch. Keep an eye on the long-range forecasts, but for now, it's a waiting game.
Rusty.

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