The Lowdown

Alright, let’s be straight with you. Blue Bay is looking pretty damn flat and grubby for the next couple of weeks. There’s one solid pulse, but you’re gonna have to dig deep for patience before it shows up.

Water temp is 18°, which is normal for this time of year, so the rubber is going on as usual.

The first real action hits Wednesday, the 16th of September. Overnight, the swell jumps to a solid 3.5m from the south with a 10-second period. The energy is cracking, with a combined reading of 2453. The early morning has a SW cross-offshore wind around 30 km/h, keeping things clean. This is serious size, though—only for the experienced lot. It backs off just a fraction Thursday morning, the 17th, to 3.0m, still from the south with that 10-second period, but the energy climbs even higher to 3193. The wind is lighter, out of the SSW at 20 km/h, and it’s clean. That’s your standout session. The wave comment is “marginal” due to tides, but it’s the best on offer.

After that, it's a slow fade. Friday the 18th has a smaller 1.6m, but the NE cross-onshore messes it up. Saturday the 19th, you get a glassy 1.0m of weak surf and only 261 energy. Surfable, but nothing to write home about.

Then the real drought hits. From Sunday the 20th onward, it's all poor surf. We see a brief bump on Tuesday the 22nd with 2.4m from the south at 9 seconds, but the cross-shore wind and chop kill it. The energy is moderate, around 965, but the quality is just not there. From the 23rd to the end of the month, it’s a real grind. The winds turn NE and stay cross-onshore, sometimes fresh and lumpy at 35 km/h. The swell stays weak, mostly under 2 meters, with short periods of 6-8 seconds. The energy readings are pathetic, sitting in the 100-300 range, and every single report says “poor surf conditions.”

There is a small bump on the 24th with 2.1m, but a fresh 35 km/h cross-onshore makes it a complete write-off. Even a period jump to 12 seconds on the 24th morning can't save it from the wind.

So, here’s the deal: if you can get out on Thursday morning, the 17th, that’s your window. Otherwise, you might as well stay home. With those persistent cross-shore winds and lumpy waves, Blue Bay is going to be more interesting for someone towing a kite than paddling a board. It’s a frustrating stretch, but it happens. Forecasts can change, but right now, that’s the story.

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.
