The Lowdown
Imperial Units
Alright, Rusty here with the lowdown on Blue Bay.
It's gonna be a bit of a snoozer to start. This weekend, the 18th and 19th of July, is nothing but onshore chop – don't even bother. The real deal shows up on Monday the 20th of July. We're looking at glassy conditions early with a clean 1.8m (that's about 6ft on the face) swell from the ENE with an 11-second period, packing moderate energy (953). That's your prime window. It's a reef break, a bit inconsistent, but when a set rolls through, it's gonna be clean and well-shaped. Water temp is 66°, right around normal for this time of year. Could be a few folks out, but it's worth the paddle.
Tuesday and Wednesday fizzle out. Thursday the 23rd throws up a 2.1m (7ft) southerly pulse, but with a 30 km/h cross-shore wind, it's gonna be a lumpy, choppy mess. Not for the timid.
Fast forward to Friday the 24th of July morning. Now we're talkin' serious grunt. A 2.5m (8ft) southerly swell with massive energy (2528) and clean cross-offshore winds. That is expert territory only. Too much water for the learner, but if you've got the nerve, it's got power and shape.
The rest of the period is small and mostly messy, with wind and rain spoiling things. Your two standout windows are Monday the 20th for clean, fun waves, and Friday the 24th for the big, heavy stuff for the pros.
Rusty out.

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.
