The Lowdown

Alright, this is Rusty, checking in for a look at what's coming up for Blue Bay over the next couple of weeks.

The outlook starts with a slow burner, nothing too exciting on the immediate horizon. A little pulse of swell shows up on Monday the 20th, but it's a tricky one. That morning's got a clean 6ft swell from the ENE with glassy conditions and a combined wave energy of 1052 (moderate). Blue Bay is a reef break and really needs that SSE direction to light up, so this is a bit of a mismatch. I'd give it a pass unless you're really desperate.

We then hit a real quiet spell. Tuesday through Thursday are flat and weak, with the swell dropping below 3ft and periods shortening. The water temp is pretty average for this time of year, so no surprises there. You're better off waiting.

Friday the 24th morning is where things start to grumble. A south swell hits 7ft, and while the direction is still not ideal for Blue Bay's optimum SSE angle, the wind is light offshore from the SW and it's clean. The combined energy is a solid 709 (moderate). It's the first real sign of life.

The weekend and early next week are a bit of a mixed bag. Saturday the 25th sees a long-period 4ft south groundswell (12 seconds), but strong cross-offshore winds mess with the shape. Sunday the 26th looks better: 6ft from the S with 647 energy, light offshore wind, and clean conditions. That's a decent window for an intermediate surf, but know that this spot can be inconsistent, and when it's on, crowds are possible.

Now, for the real story. The standout is the end of the month and the start of August. Hold onto your leash, because from Thursday the 30th through to Monday the 3rd of August, Blue Bay turns on. We're seeing a solid run of south groundswell with period up to 13 seconds and heights of 8ft to 12ft. That's big, powerful stuff - 100% expert territory, too big for beginners. The combined energy numbers are huge, hitting 3801 and even 6638 on Friday the 31st afternoon. The winds are mostly light and clean or glassy, especially on the Thursday morning with a 12 mph offshore wind from the W. This is the window.

The best session of the whole forecast? I'd lock in Friday morning, July 31st. You've got an 12ft south swell, a 13-second period, clean cross-offshore winds, and excellent conditions for experienced surfers. The energy is massive (3801). It doesn't get much better. The following days into the first week of August hold plenty of size and clean conditions, making this a true run of top-tier surf.

Just a heads-up: this is a reef break, and with that kind of long-period groundswell, the sets will have long gaps but will be powerful. Paddling out might be easier, but the take-off zone is for the confident crew only. Crowds are inevitable when it's this good.

Signing off,
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.
