The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Well, I gotta be straight with you – this outlook is a tough one. We’re looking at a long, dry spell with barely a ripple. For the first week and a half, there’s just nothing doing. The waves are tiny, the energy is weak, and the conditions are a mess. We’re talking about a stretch from Tuesday the 4th of August all the way through to the middle of the month where the swell is practically non-existent.
The only real flicker of hope comes right at the tail end of the forecast. Way out on Wednesday the 19th of August, we see a tiny pulse of energy. The swell height bumps up to a measly 2ft from the East, with a period of just 4 seconds. That’s pure wind chop, no power behind it. The combined energy rating is only 15, which is just weak. The wind is cross-onshore out of the ENE at 12 mph, so it’s going to be choppy. For a beginner-friendly, sheltered spot like Big Wave Bay, this is still pretty poor surf. The water is sitting at a warm 84°, which is pretty much average for this time of year.
Honestly, if you’re desperate for a paddle, the morning of Thursday the 6th of August looks the cleanest, with a light cross-offshore breeze, but you’ll be fighting for 0.3ft waves. That’s barely a ripple. This spot is a sheltered bay, so it needs a proper swell to get going, and we just don’t have one. For anyone looking for a proper wave, this setup is more interesting for kite surfing than paddle surfing.
So, there it is. A long blank run ahead. It’s a quiet period for this area, but forecasts can change. Keep your eye on the horizon.
Rusty.

Information about the Big Wave Bay Surf forecast
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. Our Big Wave Bay 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 (Big Wave Bay) 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 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.
