The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Tawharanui and, honestly, it’s a tough beat for the next couple of weeks. We’ve got a solid run of flatness and poor conditions stretching right across the board.
The whole 16-day window is basically a write-off for any kind of decent wave. From now right through to the end of the 16 days, you’re looking at tiny surf and very ordinary conditions. There’s a big gap of days with nothing worthwhile. The first hint of any real movement doesn’t show until around Saturday the 29th of August, and even then, it’s just a fleeting mention of surfable but very ordinary waves. That’s over five days of nothing but flat seas and poor surf.
For Tawharanui, we are talking about a beach and reef setup that needs a NE swell to get going. The water temp is sitting at 57°, which is right about average for the time of year. No surprises there.
Let’s break it down. The first week is flat. Monday the 24th through to Friday the 28th sees swell heights barely registering at 0.3 ft, with a pathetic combined swell energy of just 10. The wind is mostly offshore or cross-offshore, but there’s simply no energy to work with. It’s a total non-event.
Late on Saturday the 29th, we get a tiny pulse. The afternoon shows a 3 ft swell from the NNE with a period of 7 seconds and the combined energy climbs to 94 – that’s still weak, but it’s the best we’ll see. The wind swings offshore from the WSW at 12 mph, which would make it clean. But at that size and period, you’re not going to be getting into anything worthwhile. It’s surfable but very ordinary.
From Sunday the 30th onward, it’s back to poor surf. We get a few days of solid offshore winds, but the swell drops straight back to 2 ft or 2 ft with combined energy in the 40s and 60s. The wind gets fresh to strong later in the week, with a near gale on Thursday the 3rd of September making paddling out a real mission.
There’s one more faint flicker around Saturday the 5th of September, with a 4 ft NW swell, but the period is a short 5 seconds, the wind is cross-shore, and the combined energy is only 72. It’s messy and weak.
Honestly, there’s nothing here to get excited about. The best call in this whole outlook is that Saturday the 29th of August afternoon, but even that is a tough sell. For the rest, you’re better off doing something else. The wind is often offshore, which would clean things up if there was any swell, but there just isn’t. It’s a blank run, and for Tawharanui, this kind of extended flat spell is fairly normal for this time of year.
Stay patient, mate. Forecasts can change.
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.
