The Lowdown

Alright, Rusty here, let’s get into what’s on the table for Blue Bay over the next couple of weeks.

Honestly, it’s a bit of a slow start. The first week and a half are looking pretty ordinary, with a lot of small, weak swell and messy wind. There are a couple of windows where things clean up, but you’ve got to be patient. The real standout looks to be the very end of the run, around Friday the 5th and into the 6th, where the energy finally comes alive.

For the first few days, from Monday the 24th right through the end of August, it’s mostly small surf – around 1 ft to 5 ft – but the wind is all over the place. Most of the time it's cross or onshore, keeping it choppy and pretty poor. You’ll see the odd window of glassy conditions, like Saturday morning the 29th and Monday morning the 31st, but the swell’s tiny and weak. The energy reading is barely cracking 200-300 (combined swell energy) on those days, so it’s not doing much.

We've got a bit of a dry spell in the middle where it's all knee-high mush. The water temp is about average for this time of year, so a normal tropical wetsuit or just boardshorts are fine for Blue Bay.

Now, Wednesday the 3rd of September is where things start to perk up a little. The swell stays small, only 1 ft to 3 ft, but the wind goes light offshore or cross-offshore from the WNW and NW. That’ll clean the waves right up. The energy is still on the low side (93 to 187), so it's not going to be pumping, but for a sneaky, clear, glassy session, you could get some fun little peelers. It's a reef break, so it'll hold that small SSE to S swell.

The real highlight has to be Friday morning the 5th of September. Overnight, the combined energy jumps to 617! That’s a solid boost of moderate wave energy. The swell will be a clean 3 ft from the S, with a nice 11-second period – that's proper groundswell. And the wind is a gentle cross-offshore breeze from the SSW. That means clean, lined-up waves. Keep in mind, for a south-facing reef like Blue Bay, that light offshore wind and solid S swell should make for some of the best waves in the whole fortnight. It’s surfable for intermediates, not too big. If it gets a bit bigger than forecast, keep an eye on the tide.

After that peak on Friday morning, the swell drops off again and the wind turns nasty by the afternoon and through the weekend, getting fresh and onshore. So, if you want the best of it, focus on that Friday morning, September 5th. Even the Thursday afternoon before (September 4th) with a clean 3 ft S swell and 288 energy is a good bet for a clean, smaller session. Don't waste your time on much else before that.

Stay stoked,
Rusty

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.
