The Lowdown
Alright, let’s talk Blue Bay. This reef is a fickle one, and over the next 16 days, we’ve got a long stretch of nothing to start. Water temp is about what you’d expect for the season.
The first real window opens Friday morning, August 14th. The wind goes glassy, WSW at just 3 mph, and we’ve got 4-foot south swell at 10 seconds. Combined energy is 314 (moderate), and the reef should handle that south groundswell. Conditions are glassy, so that’s a big plus. Then it goes quiet. The next few days are all onshore chop and poor surf. The wind shifts east, which isn’t Blue Bay’s friend. The next chance is Wednesday morning, August 19th, when the wind goes glassy again with a light NNE breeze. Swell is 4-foot from the ESE, but the period is short at 7 seconds, and the energy is very weak at 164. Surfable, but nothing to write home about. Another dry spell follows. Saturday, August 22nd, and Sunday, August 23rd, have clean offshore winds, but the swell is tiny—3 to 4 feet—and the energy stays low. It’s surfable, but average. The end of the forecast gets a little spicy. Early Wednesday, August 26th, the wind is clean cross-off, but the swell is barely 1 feet. Then, Wednesday afternoon, August 26th, a bigger pulse hits: 10-foot south swell at 11 seconds, with a fresh cross-shore wind. Energy jumps to 1793 (very strong). That’s a lot of power, but the lumpy cross-chop makes it marginal. This is expert-only, and the reef might hold, but it won’t be clean. The standout is Friday morning, August 14th, for a glassy, clean session on a 4-foot south swell. The rest is mostly waiting and watching the wind.

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.
