The Lowdown
Alright folks, Rusty here. Let’s have a look at what Tawharanui’s got cooking for us over the next couple of weeks. I gotta be straight with you – it’s a pretty bleak run for the most part. We’re staring down a long stretch of barely anything ridable, so patience is the name of the game.
The forecast kicks off with a real dud. From Tuesday the 25th of August right through to the 1st of September, wave heights are just a pathetic 0.3 ft to 3 ft. The combined wave energy is weak, barely hitting double digits for days on end (7 to 9). The wind is all over the shop – cross-off, onshore, glassy, it doesn’t matter because there’s no swell to work with. It’s poor out there.
We do get a tiny bump on Saturday the 29th of August with a 4 ft north swell, but it comes with a nasty north cross-on wind and a weak period of 7 seconds. The energy jumps to a moderate 162, but the conditions are a mess. The next glimmer is Sunday the 30th of August morning. Clean offshore winds from the SSW with a 3 ft wave, but that combined energy is still a weak 95. It’s surfable, but barely. Honestly, this whole first week is a write-off for a proper paddle.
Now, here’s the one thing that’s got my attention. Look ahead to Monday the 7th of September. The morning session is the standout of the entire 16-day outlook. We’ve got a 5 ft swell rolling in from the north, with a period of 7 seconds – not long period, but it’ll be plenty full enough. The combined energy hits a solid 368, making for some proper push. What makes it a winner is that glassy, offshore wind from the WSW. That means Tawharanui’s beach and reef setup should be clean, punchy, and fun. It’s still a bit of a trek out, so don’t pin your hopes on it just yet, but keep that date circled. It’s the only day that looks like it’s worth the drive. The crowd factor is ‘often’ busy here, so get in early if it’s on.
After that, it fades back into small stuff and messy winds. Tuesday the 8th of September and Wednesday the 9th are back to tiny, weak, onshore slop. A real shame.
So, bottom line: you’ve got a long drought until Monday the 7th of September. That’s your only real window for something fun. The rest? Leave the board in the car.
Stay patient, Rusty.

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