The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough one. We’re looking at a long, drawn-out flat spell for Tawharanui with only a couple of brief, very average moments. For the most part, you’ll be staring at a lake.
The trouble starts now. We’ve got a solid 16-day window, but the first recommendation doesn't appear until Monday the 7th of September, and even then it's a miss. We see a jump in swell energy – up to a moderate 246 (combined energy) – with a 6ft swell from the north. But that’s coming with a strong, lumpy cross-onshore wind from the NNW at 19 mph. It’s messy, blown-out, and with that short 6-second period, it’ll be a washing machine. Not for paddle surfing. This setup actually looks more interesting for kite surfing than paddle surfing. Keep the board on the roof.
Tuesday the 8th of September is the closest we get to a surf. The swell settles to 4ft from the north with moderate wave energy (166). The wind shifts to a cross-offshore from the west at 9 mph, cleaning things up. It’s surfable, but the report calls it “very ordinary.” The water temp is about average for this time of year. For a beginner-friendly spot like Tawharanui, that 4ft is fine, but the quality is just meh.
After that, it’s back to tiny, weak pulses of swell with energy figures in the teens and twenties. We see long-period (12-14 second) groundswell from the NNE, but it’s only 0.7ft to 1ft. The wind is often offshore, which would be a major positive if there was any wave to hold up. It stays like this for days. You’ll get clean conditions, but nothing to ride. A couple of times the wind is so strong (up to 28 mph) it’s clean but hard to paddle into.
There’s another blip on Thursday the 17th of September with a 5ft NNW swell and moderate energy (155). Cross-offshore wind from the WSW at 19 mph keeps it clean. But again, the period is short (5 seconds), meaning weak, crumbly waves. Not a standout.
Friday the 18th of September has a small pulse of east swell at 3ft with gentle offshore wind, but it’s still only a 1 out of 10 call.
Honestly, if you’ve got itchy feet, don’t set your hopes high. The only window with a pulse is Tuesday the 8th, and even that’s ordinary. The rest is a waiting game.
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.
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.
