The Lowdown
Alright, listen up. Wainui Bay Chalet is the only spot on the menu for the next couple of weeks, and it’s got a bit of a story to tell. The water temp is sitting at 57°, which is pretty much bang on average for this time of year, so no nasty surprises when you drop in.
The weekend kicks off this Saturday the 18th with a clean 4ft swell from the ESE, running on a 14-second period. The morning is the go with a light offshore breeze, and the combined energy is pumping at 932. It’s not the biggest, but those long-period lines will be clean and fun for an intermediate. The afternoon gets a bit sketchy as the wind swings cross-on, so do the dawn patrol.
Now, Sunday the 19th morning is where it gets real. We’ve got a 5ft SSE swell with a very long 18-second period, and the energy is thumping at 1734. With a light offshore wind, you’re looking at classic, lined-up sets. This is a standout for the experienced crew – the power is there, but at 5ft, it’s still manageable for a keen intermediate if you’re feeling it. The afternoon is a write-off though, with a strong cross-on wind ruining it.
Monday the 20th is a bit of a letdown. The morning is choppy and cross-on, not worth paddling out. The afternoon has a 5ft swell but it’s messy. Skip it.
Tuesday the 21st is a sneaky good one. The morning is clean with a 5ft SSE swell, 16-second period, and a light offshore breeze. The energy is solid at 1405. This is another top session for the more experienced surfer. The afternoon stays clean but the swell drops a touch.
Wednesday the 22nd and Thursday the 23rd see the swell fade. Wednesday morning has a clean 3ft from the SSE with a light offshore, but it’s small. Thursday morning is even smaller at 2ft. It’s surfable but nothing to get excited about.
Friday the 24th is tiny, with 2ft to 2ft from the E. The wind is offshore both morning and afternoon, so it’s clean, but you’ll be on a log or a longboard if you bother.
Then we hit a dry spell. From Saturday the 25th through to Monday the 27th, it’s a total mess. Strong winds, rain, and poor conditions. Don’t even think about it. That’s a solid three-day gap of rubbish.
Now, for the long-range promise. Wednesday the 29th of July is looking like the big one. We’ve got a 6ft ESE swell, 13-second period, and a gentle offshore wind. The combined energy is a massive 1282, and the forecast says excellent conditions for experienced surfers. This is a true standout for the second week – powerful, clean, and likely to be a proper session. The afternoon holds at 6ft with a light breeze, still excellent. The Thursday the 30th is also solid with a 5ft ESE swell and clean conditions.
The end of the month and start of August get a bit messy again with strong winds and poor quality, but there’s a small window on Sunday the 2nd of August morning with a clean 4ft from the SE and a light offshore.
So, if you’re asking me, Rusty, the absolute best of the bunch is Sunday the 19th morning. The 5ft SSE groundswell with that 18-second period, light offshore, and huge energy is a proper session. The backup is Tuesday the 21st morning, and if you’re looking at the longer range, Wednesday the 29th is the one to circle on the calendar.

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.
