The Lowdown
Alright folks, Rusty here. Let’s break down what’s brewing for Blue Bay over the next couple of weeks.
First off, we’ve got a bit of a lull. The first few days are a mess with cross-off winds and weak, short-period swell. Not worth wetting your wetsuit for. The real window opens up on Monday, July 20th, and that’s where it gets tasty.
The standout session is Monday morning, July 20th. The water is sitting at 66°F, which is about average for this time of year, so no chills. The swell is a solid 6ft from the east, and the wind is glassy – dead calm, perfect, clean. The combined energy is moderate (816), so there’s some grunt in it. For an inconsistent reef, this is a rare gem. The crowd factor is possible, so get your spot early.
Tuesday, July 21st, is still a good shout. The morning brings a 5ft, east-northeast swell with a light cross-off breeze from the NNW, keeping the surface clean. The energy is a bit lower (482), but it’s a fun, manageable wave. The wind is light, so it’s a solid session if you missed the Monday magic.
The rest of that week gets chewed up by onshore winds, but circle Sunday, July 26th. The morning delivers a solid 7ft groundswell from the south, clean with a light cross-off breeze. The combined energy is strong (1015), and the period stretches to 10 seconds, so there’s some punch. Watertemp is still average, but the conditions are prime. Remember, this is a reef, and a long-period south swell can make it a bit straight, but it’s the best of the second week.
Monday, July 27th, follows with a similar 6ft south swell, glassy in the morning, but the period is a very long 13 seconds. That’s real groundswell, which can be tricky on a reef or beach, but with the offshore wind, it’s a solid option for the experienced crew.
After that, the swell drops off and the winds turn messy. There are a few clean mornings, but the wave heights fall below 3ft, and the energy is weak. Not worth the paddle.
So, the best bet is Monday, July 20th, with the glassy east swell, and then Sunday, July 26th, for the bigger south groundswell.
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.
