The Lowdown

Alright, let's get into it. This is Rusty, and I'm looking at the next couple of weeks for Wainui Bay Chalet. The water is sittin' at 56°, which is a bit colder than normal for this time of year, so make sure you've got a decent wetsuit.

We've got a bit of a slow start, but the real action kicks off on Tuesday the 21st. That morning, the swell is comin' in at 5ft from the SSE, with a long period of 16 seconds – that's proper groundswell energy. The wind is light and cross-off from the WSW, so the waves will be clean. The combined energy is sittin' at 1379 (moderate), and the conditions are rated excellent for experienced surfers. This is the standout session of the whole outlook. The swell direction is right on the money for the optimum SSE, and with light offshore winds, it's goin' to be a treat. Just a heads up, with a period that long, the waves might be a bit too straight for the beach, but at this size, it should still be fun.

The next morning, Wednesday the 22nd, we get a smaller but cleaner morning. Swell drops to 3ft from the SSE, period 13 seconds, and the wind is pure offshore from the NW at 3 mph. It's glassy, and the energy is weak (295). It's a good option for a quieter, smaller-wave session.

Thursday the 23rd is still small, with 2ft to 1ft SSE swell and offshore winds in the morning. The energy drops to 107 (weak) and then 86 (weak). It's surfable but very ordinary.

Then we hit a dry spell. Friday the 24th through to Sunday the 27th is mostly a write-off. There's a big spike of 21ft swell from the S on Monday the 27th morning, with massive energy (24676), but that's way too big for this break – only for the absolute crazy experts, and even then, it's risky. The wind on that Monday afternoon is strong cross-shore at 25 mph, makin' it a mess.

We get a proper clean-up on Tuesday the 28th morning. Swell is 6ft from the ESE, period 14 seconds, with a gentle offshore wind from the WNW at 9 mph. The energy is moderate (1420), and it's another excellent session for experienced surfers. The wind is clean, and it's a solid, lined-up groundswell.

The next day, Wednesday the 29th morning, is also good. Swell at 4ft from the ESE, period 13 seconds, light cross-off wind from the WNW. Energy is 666 (moderate). It's a very good session, but not quite as strong as the Tuesday.

From the 30th of July through to the 2nd of August, the swell hangs around 2ft to 5ft, mostly from the SSE or ESE, with light winds. The best of this stretch is the morning of Sunday the 2nd of August, with a 5ft SSE swell, 15-second period and light cross-off wind. Energy is 896 (moderate), and conditions are very good. It's worth a look if you're around.

After that, the forecast drops off into small, weak swell and poor conditions for the first few days of August.

So, the clear standout is Tuesday the 21st of July morning. The next best is Tuesday the 28th of July morning. Get out there for those if you can.

Rusty.

Information about the Wainui Bay Chalet Surf forecast

The above surf forecast table for Wainui Bay Chalet provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wainui Bay Chalet can be found by selecting the local surf guide option on the grey menu. Our Wainui Bay Chalet 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 (Wainui Bay Chalet) 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 Wainui Bay Chalet 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.
