The Lowdown
Alright, grab a coffee and listen up. I’m Rusty, and I’ve been staring at this forecast for a while. The honest truth is, it’s a grim run for the next sixteen days at Big Wave Bay. There’s a massive gap of nothing for the first week and a half, so leave your board in the car for now.
The first sign of any life won’t show up until the morning of the 28th of July, and even then it’s just a tiny 0.3ft ripple from the SE with a period of 12 seconds. The combined energy is a measly (10) – that’s barely a bump. The wind is light and offshore, which would be a major positive if there was any swell to clean up, but there isn’t. It’s a beginner-friendly spot, sheltered from the swell, and the water temp is about average for the time of year at 84°F.
Things stay tiny and poor through to the 30th of July. The only real shift happens on the afternoon of the 30th, where we finally see a 3ft SSW swell, but it’s wind swell with a short period of 6 seconds, so it’ll be weak and crumbly with a combined energy of (74). The wind turns cross-offshore and clean, but honestly, for a sheltered beach break like this, it’s looking more interesting for a kite surfer than a paddle surfer. The waves are too small, too short-period, and the quality is just poor. It’s a blank run, and for this area, that’s not unusual.
Rusty.

The above surf forecast table for Big Wave Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Wave Bay 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 Big Wave Bay 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.
