The Lowdown
Alright, let me break it down for you. The next couple of weeks look pretty quiet for Blue Bay. There's a lot of small, weak swell and poor conditions in the mix, with a few windows of decent surf if you're patient.
The first real chance to get wet comes on Sunday the 23rd, in the morning. It's been a bit of a flat spell before that, but glassy conditions with a light wind from the NE will kick in. The swell is a modest 4 ft from the south, with a period of 11 seconds, making it a long-period groundswell. The energy is moderate (316), and the glassy wind is a major positive for clean surf. Blue Bay is a reef break, so that longer period should wrap in nicely.
The next standout is on Thursday the 27th, again in the morning. We'll see a similar setup: a 4 ft south swell with an 11-second period, but the energy is stronger this time (522) – that's moderate to strong. The wind is dead calm, glassy, so it'll be clean. Same story on Friday the 28th morning: 4 ft from the south, 10-second period, moderate to strong energy (422), and glassy conditions. The wind will be light from the NNW, so it'll be near-perfect.
Looking further out, into the first week of September, the surf picks up a bit. Saturday the 5th morning has a solid 6 ft south swell, 10-second period, with strong energy (679). The wind is light from the north, making it a clean cross-shore. The swell is getting up there, but it's still in the intermediate-friendly range. The direction is from the south, which is a good match for Blue Bay's optimum SSE swell direction.
Water temp is sitting at 64°F, which is about 1°F cooler than the long-term average – nothing unusual, just a touch on the cool side for this time of year.
So, if you're looking for the best, aim for the mornings of August 27th and 28th. The glassy conditions and solid south swell should make for some nice, clean waves at Blue Bay. The Saturday the 5th of September morning is also promising, but it's further out, so treat it with a touch of caution.

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.
