The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Tawharanui over the next couple of weeks.
Honestly, mate, it’s a bit of a flat spell. We’ve got a long run of tiny, weak waves and the only break on offer is Tawharanui itself, a beach and reef setup that’s fairly consistent but only really works with swell from the NE. The water temperature anomaly is about average for this time of year, so no surprises there.
The first proper window to even consider comes up on Sunday the 6th of September, but it’s a bit of a letdown. Sunday afternoon pushes a 5ft swell from the N with a short, weak period of 6 seconds and a moderate cross-onshore breeze that’ll have it choppy. The combined wave energy is moderate (126), but the conditions are poor. Not one to get excited about.
Monday the 7th of September is the standout of the whole forecast – and I’m saying that with a heavy heart because it’s not much. Monday morning sees a 4ft N swell at 7 seconds with clean, cross-offshore winds from the WNW. The energy is moderate (164), and for a few hours it’ll be the cleanest we see. Monday afternoon drops to 3ft but picks up a proper offshore from the SW, so the waves will be clean and lined up, even if they’re small. It’s surfable, but very ordinary.
After that, we go straight back into the doldrums. From Tuesday the 8th all the way through to the end of the 16-day window, it’s tiny dribble – mostly 0.3ft to 2ft, with long-period NE groundswell that looks great on paper but won’t produce anything rideable here. Periods crank up to 13-15 seconds from the 10th onwards, but with no size to back it up, it’s just a lot of movement with nowhere to go. Winds are often offshore or clean, but you can’t paddle a ripple.
The long-range stuff from the 14th to the 18th September is all under 1ft and not worth the walk down the beach. Crowds are often a problem at Tawharanui, but with conditions like this, you’ll likely have the place to yourself – for good reason.
If you’re itching for a paddle, Monday the 7th is your only real chance. After that, it’s a two-week blank.
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.
