The Lowdown

Alright, Rusty here. Let's take a look at what's happening at Blue Bay over the next couple of weeks.

First thing’s first, the water temp is sitting around 65°F, which is pretty much dead average for this time of year. No surprises there.

Right now? There's nothing doing. We've got a dry spell from today through to the end of the first week. The swell is tiny, the wind is messy, and the scores are low. You’re better off doing something else. Then, Monday the 7th morning shows a glimmer of hope. We’ve got a glassy, clean 5ft S swell rolling in, with a period of 8 seconds. The energy is moderate (321). It’s on the smaller side and inconsistent, but for a Monday morning, if you’re desperate, you might score a few clean ones. Crowds are only a sometimes thing here, so you might have it to yourself.

The real standout, the one to circle, is Tuesday the 8th. The morning serves up a solid 8ft S swell (period 9 seconds) with a clean, cross-off breeze. That’s proper surf, with strong energy (1033). This is getting into expert territory at 8ft, so leave the foamies at home. The afternoon pushes even bigger, hitting 8ft from the SSE on a 11-second period, with a gentle cross-shore. The energy jumps to a beefy 1486. That’s the pick of the whole window – a big, powerful groundswell. Wednesday the 9th drops back a notch but stays fun.

Into the second week, the quality gets more questionable but the size hangs around. Thursday the 10th sees a big 10ft S swell, but it’s blowing a fresh 19 mph cross-off wind. It’s clean, but that’s heavy duty, expert-only stuff with massive energy (2216). Friday the 11th is still solid at 8ft on a long 12-second period from the S, moderate cross-off breeze. Energy is still pumping at 1812. Saturday the 12th morning might be the best of the week: 6ft S swell, clean, gentle cross-off breeze. That’s a much more manageable size for the advanced intermediates.

After that, it fades fast. The 18th to 19th show a monster pulse right at the end of the forecast – 12ft S swell with a very long 14-15 second period – but it’s blown out with onshore or cross winds, so the quality is a mess. That’s one for the big-wave chargers to look at, but it's a long way out.

Overall, don’t bother this week until Monday. The clear standouts are Tuesday the 8th for the big power and Saturday the 12th for a cleaner, more manageable session.

Stay wet, 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.
