The Lowdown

Alright, this is Rusty comin' at ya from the beach.

The next 16 days are a real mixed bag for us. We’re lookin’ at a lot of time where the conditions just aren't gonna be kind to a paddler. There’s a big gap of poor surf from now all the way through until Thursday morning the 13th of August, so don’t even bother waxing the board for the first few days. It’s a pretty bleak start.

We’ve got one real standout and that’s Friday morning the 14th. That’s your window. Blue Bay is the spot. It’s the only time in this outlook that everything clicks. We have a clean 4ft swell coming from the south with a solid 10-second period, and it’s gonna be glassy – dead calm wind. That’s rare, and it’ll make for some gorgeous, clean lines. The energy in the water is moderate (363). The water temp is sittin’ around 64°, which is about average for this time of year – nothing shocking.

Now, after that, it gets real ordinary again. Saturday the 15th is cross-shore with light rain, not really worth paddling out with the messy conditions. Sunday the 16th the wind picks up onshore and it’s choppy. That run of ordinary and poor surf stretches all the way into the middle of the next week. The swell is small and the wind is just never in our favour for Blue Bay.

There’s a flicker of hope on Wednesday morning the 19th with a little offshore wind and some clean 4ft swell, but the period is short (7 seconds) and the energy is weak (212). You might get a couple of fun ones if you’re desperate, but it’s nothing to write home about. Thursday the 20th morning is glassy again with a tiny 4ft swell – same problem, low energy and short period (121).

Looking into the second week, things stay pretty flat and wimpy. We get a long stretch of tiny 2ft to 3ft swell from the ENE. The wind is offshore for a few days, so it’ll be clean, but there’s no power behind it. Good for a longboard cruise maybe, but not for a real session. The week closes out with a big spike in energy on the 27th – a solid 6ft S swell with an 11-second period and massive energy (873) – but it’s blowing a 25 mph cross-offshore wind, which just makes it a wild, messy ocean. That’s more kite-surfing territory than paddle-surfing. The next day, a 7ft S swell (1266) is just going to be a washing machine with those strong onshore winds. Avoid it.

So bottom line: nail that Friday morning glass-off. It’s the best of a bad bunch.

Information about the Blue Bay Surf forecast

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