The Lowdown

Alright folks, Rusty here. Let’s get into it for Blue Bay.

First up, the water temperature is sitting at 65°, which is right on the money for this time of year – no surprises there.

The next week and a half is a bit of a mixed bag, but there’s a real standout window coming up. The pattern starts off pretty ordinary. Through Friday the 17th and Saturday the 18th, we’ve got small, weak swell with bumpy, cross-onshore winds, so it’s not worth paddling out for. Sunday the 19th sees a bit more size pushing in at 7ft, but it’s still messy with cross-onshore wind and the wave energy is moderate. Not your day.

Monday the 20th is where things flip. The morning is absolute magic – glassy conditions with a light offshore wind from the NW, clean 5ft swell from the ENE, and a solid 10-second period. The combined energy is strong. This is the pick of the first week. Blue Bay reef will be handling that direction well, and with the glass, it’s going to be clean and fun. The wind stays light offshore or glassy right through to Tuesday morning, so you can milk that little window. The swell drops a bit by Tuesday afternoon, but the morning session on the 21st is still a good call with 5ft and glassy conditions.

After that, we hit a flat spell. From Wednesday the 22nd through to the end of the month, the swell drops off significantly – mostly under 3ft, with weak energy. There are a few clean mornings, like Thursday the 23rd morning and Saturday the 25th morning, but the waves are small and ordinary. Not worth getting excited about.

Now, looking ahead to the second week, there’s a promising pulse showing up. Wednesday the 29th of July brings a solid 8ft S swell with a 10-second period and strong energy, but the wind is a moderate cross-offshore from the NW. That’s clean, but with that size, it’s going to be a handful – more for experienced surfers. The combined energy is strong. It’s a bit of a cleanup set, but the quality is marginal due to the wind angle. Still, it’s the only real size on offer in the whole forecast. The following days hold similar size but with lighter winds, so keep an eye on it.

If you’re a beginner, the 5ft to 5ft sessions on the 20th and 21st are your best bet, but the 8ft on the 29th is too big for you.

So, the standout is Monday the 20th and Tuesday the 21st in the morning – glassy, clean, and fun waves. The late July pulse is promising but less certain.

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.
