The Lowdown
Alright, let’s break it down for Blue Bay. This reef is inconsistent at best, and the next week and a half is mostly dead. Water temp’s about 57°F, right where it should be for this time of year. Starting Thursday the 20th, we get a weak, short-period ENE windswell around 4ft, but it’s trashy with strong cross-onshore wind – not worth paddling out.
Friday the 21st through Tuesday the 25th is a total lull – tiny surf, messy conditions, no real energy. Saturday morning the 22nd has a clean 1ft wave with offshore wind, but it’s gutless. You’d be floating.
Here’s the real deal. Wednesday the 26th of August. A solid southerly pulse hits 10ft in the morning, dropping to 8ft in the afternoon. That’s big, expert-only territory – anything over 8ft gets serious. The period is short at 8 seconds, so it’s windswell, not groundswell, but the wind is offshore from the WSW, keeping it clean and lined up. Combined energy is strong at 1207 in the morning and 836 in the afternoon – plenty of power. Blue Bay is fairly exposed to SSE swell, and this south swell will wrap in well. If you’re experienced, this is your day. Crowds are only sometimes an issue, so you might have a few buddies out.
After that, Thursday the 27th drops back to weak 3ft surf, and the rest through early September is mostly small, short-period, and onshore. Saturday the 29th has a morning with clean offshore wind but only 4ft of weak swell – rideable but nothing to write home about. A couple glassy mornings pop up in early September, but with just 2-3ft and low energy, it’s a small-wave session at best.
Bottom line: the only real highlight in this 16-day stretch is Wednesday the 26th of August. If you can handle the size, go for it. Otherwise, it’s a long wait.

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.
