The Lowdown

Alright, mates, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a lot of small, weak swell and wind directions that just aren’t doing us any favors. It’s going to be a waiting game for the most part.

We start off with a glimmer on Tuesday morning at Tawharanui. The swell is tiny, only 2ft from the east, and with a light offshore breeze, it will at least be clean. The energy is weak, coming in at just 41, and while it’s surfable, it’s pretty ordinary. The water temp is 58°F, which is about normal for this time of year. Don’t expect much more than a few small, crumbly waves for the beginners.

Then we hit a real flat spell. From Tuesday afternoon all the way through to Saturday the 23rd, it’s basically nothing. We’re talking waves under 1ft and energy readings dropping to single digits. There’s a little pulse of 4ft on Sunday the 23rd, but it’s short-period windswell from the northwest, and with a fresh cross-offshore breeze, it’s just not going to be any good. That whole stretch is a write-off.

The flatness continues into the following week, with tiny waves and cross-shore winds making things messy. We do see a bit of a bump on Thursday the 28th, with a 4ft northwest swell, but the wind will be cross-onshore and choppy, so it’s not worth getting excited about.

Now, here’s the one that might have a bit of life in it: Saturday the 29th. We’re looking at a push of 5ft from the NNW, with a moderate cross-offshore wind. The energy jumps up to a moderate 246, which is the strongest we’ve seen in the whole run. It’s still not massive, but that combination of size and clean wind makes it the standout of the fortnight. The swell direction is a little off from the optimum, but it’s the best on offer. Just be aware this is over a week away, so treat it as promising, but not set in stone.

After that, it fades back down again. The 30th has a tiny 2ft and glassy conditions which would be nice if there was any power behind it. The first of September shows a clean 3ft in the morning, but it’s weak.

Honestly, for most of this period, the setup at Tawharanui’s beach and reef looks more interesting for the kite surfers than for us on a paddleboard. The waves are just too small and weak to do much with.

Hang in there, and keep an eye on that Saturday the 29th.

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.

Tawharanui is 48 km (30 miles) from the city of Northshore. If you plan a holiday in Northland, look for hotels and other accommodation in Northshore. Northshore has rooms for a wide range of budgets as well as car hire and transport links.
