The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s coming up for Wainuiomata Reefs.

Alright, the outlook is a bit of a mixed bag, with a long stretch of nothing too exciting before a big pulse of energy shows up. We’re starting off with a decent-sized but messy swell. On Wednesday the 5th of August, a solid 13ft southerly swell rolls in, but it’s got a brutal 25 mph southerly wind blowing straight onshore, so it’s a write-off – just clean your board instead. That energy is massive though, with combined swell energy hitting 4530 (strong to very strong). Thursday the 6th looks a bit better. The swell drops to 6ft from the SSE, and by the afternoon we get a lighter NNW breeze going cross-off, making for some clean, surfable waves. It’s not huge, but it’s a chance to get wet.

Then we hit a dry spell. From Friday the 7th through to roughly the 16th of August, the surf is either too small, too windy, or just plain messy. There are a few mornings with clean conditions and small swell, like the 9th with a fresh offshore N wind and 4ft SSE swell, but the energy is weak (273). It’s really just a paddling session. The real action is a long way off.

Mark your calendars for Monday the 17th of August. That’s the standout. The forecast is showing a massive 18ft to 20ft south swell, with the combined energy getting up to 10192 (very strong). That’s a serious groundswell with a 12 second period – it’ll have plenty of push. The wind is looking light and offshore or cross-off through the morning and afternoon. Now, this is a reef break, so that long-period swell is going to be a proper beast. With waves over 8ft, this is for experts only. The water temperature is about 55°F, which is pretty normal for this time of year, so suit up.

Tuesday the 18th of August is still pumping, with 12ft to 10ft surf from the south, clean conditions, and light winds. That’s another solid day for experienced surfers, but the energy is still high at 2816. The week after that settles back into smaller, more manageable 3ft to 7ft swells, but the winds are mostly cross-off or light, so you can get some fun ones in if you’re keen.

The big call is that Monday the 17th. It’s a long way out, so we’ll keep an eye on it, but if it comes together, Wainuiomata Reefs is going to be a proper cauldron. Don’t be a hero if you’re not ready for it.

Rusty.

Information about the Wainuiomata Reefs Surf forecast

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