The Lowdown

Righto, let’s have a look at what Tawharanui’s got cookin’ for us over the next couple of weeks.

First up, we’ve got a bit of a slow start. The real action doesn’t kick off until Monday morning, August 10th. Before that, it’s flat and quiet, so don’t bother paddling out.

Monday morning’s looking like the clear standout of the whole run. We’ve got a clean 5ft swell coming from the north, with a light offshore breeze from the southwest. That’s proper glassy conditions, and the water temp is sitting at 58°F, which is pretty much spot-on for this time of year – no surprises there. The combined energy is a moderate 269, so there’s enough push to get into some fun ones. This is about as good as it gets in this window. Monday afternoon, the swell drops to 4ft, but the wind swings to a light offshore from the west-southwest, so it’ll still be clean, just a bit smaller.

Tuesday morning stays clean with a 4ft north swell and a cross-offshore breeze from the southeast. It’s not a standout, but it’s surfable. The energy drops to 159, so it’ll be weaker. By Tuesday afternoon, the wind turns cross-onshore, and the quality goes downhill fast.

From Wednesday through to the end of the first week, we’re looking at onshore winds, messy conditions, and poor surf quality. Wednesday morning has a lumpy 5ft northeast swell but with a strong onshore breeze – that’s gonna be a choppy, blown-out mess. The combined energy is 333, which is moderate, but the wind kills it. This stretch is a write-off for a paddle surfer; if you’ve got a kite, it might be interesting.

The weekend of August 15th and 16th sees the swell drop right off. Saturday morning has a tiny 3ft northeast swell with a cross-offshore breeze, but it’s just too small to get excited about. Sunday has even less – 2ft to 2ft – with a strong offshore wind that’ll keep it clean, but you’d be scratching for a ride.

The second week is mostly bleak. Swell heights hover around 1.0ft to 2ft, with persistent onshore winds and very weak energy readings (most under 100). The best you could hope for is a tiny clean session on Tuesday August 18th afternoon, with a 2ft east swell and a moderate offshore breeze. But it’s a long shot.

One thing to note: throughout this whole period, Tawharanui is an exposed beach and reef setup, best on a northeast swell. Monday morning’s north swell combined with that perfect offshore wind is the only real highlight. Crowds are often there, so if you do go out Monday morning, expect some company.

So, to sum it up: Monday August 10th morning is your one true standout. Get out there early. The rest of the 16 days is mostly small, weak, and blown out. It’s a lean stretch, but that’s how it goes sometimes. The forecasts can change, so keep an eye on it.

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.
