The Lowdown

Alright, crew, Rusty here. Let’s talk about the surf on the horizon. It’s a bit of a mixed bag, so let’s break it down without wasting time.

The forecast kicks off with a slow start, but don't get disheartened. The first real opportunity to get wet is early next week, and there's a proper window of clean surf that you won't want to miss.

Looking at the first day, Wednesday morning we’ve got some southeast swell pushing in at around 4ft. The wind is glassy, light from the west, and it’s looking like a clean, fun morning at Wainui Bay Chalet. The water temp is sitting at 56°, which is right around the average for this time of year. The swell is a bit short in the period, only 8 seconds, so the waves might not have the punch of a big groundswell, but it’s a good start. The combined energy is moderate (212), so there’s a bit of push behind it.

The conditions go downhill a bit on Thursday. The swell drops off, and the wind swings around. The morning has some offshore wind, but the waves are tiny. It's surfable, but not anything to write home about.

The weekend looks like a bit of a washout. Friday morning brings some light rain and a shifting, bumpy onshore wind, making for poor conditions, and the swell is messy. Saturday is worse, with the wind howling and the ocean all over the place. The swell is small but with a long period, which at this spot might just make it close out. It’s not looking like a weekend for the board.

Now, here’s where things get interesting. Sunday the 13th is the standout of the whole run. Early in the morning, the swell jumps to 5ft out of the SSE, with a long, powerful period of 15 seconds. The wind is glassy, coming from the WSW, just about dead flat and clean. This is a proper groundswell, and the energy readings are very strong (1017). This is the one we’ve been waiting for. The wave direction is also spot on for Wainui Bay Chalet. This is a session for the more experienced surfer; the size and power will be challenging, but it will be well worth it. One for the memory bank.

The good conditions carry into Monday the 14th, but the swell drops a little to 4ft and the period eases to 13 seconds. Still, the morning looks clean with a light offshore NNW breeze, and it should be a really good, solid day. The energy is still strong (580), and the waves should be nicely shaped. Another morning where you’ll want to be out there.

After that, the surf starts to fade. Tuesday morning has a smaller, slower wave, around 3ft, with a gentle offshore wind, but it's nothing compared to the weekend. The week after that is pretty quiet. The swell gets pretty small and there are long gaps with barely any rideable surf. The wind is mostly offshore or clean, but there just isn’t any ocean energy to work with.

Looking further out, there are a couple of days around the 18th and 19th where the swell picks back up to around 3ft, with some good offshore winds. It might be worth a paddle, but it’s on the small side. The real magic is happening in that window from early Sunday morning through Monday. That's our window.

So, the long and short of it is: don't waste your time on the weekend, save your energy. Sunday morning the 13th and Monday morning the 14th are the days. Get out there, get some, and be safe.

Rusty.

A general guide to surfing at Wainui Bay Chalet can be found by selecting the local surf guide option on the grey menu.

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.
