The Lowdown
Alright, Rusty here. Let’s cut to it – this outlook for Tawharanui isn’t pretty. The whole 16-day window looks flat and quiet. A long dry spell.
From Tuesday the 25th of August right through to Thursday the 27th, the swell is barely a ripple at 0.3 feet. Northeast direction, short period around 10 seconds, and the energy is weak (7). Water temp is about average at 57°. Just nothing going on.
We get a little bump on Friday the 28th with a 3 foot northerly swell, but the period is a poor 5 seconds and onshore winds chop it all up. Not worth the drive.
Saturday the 29th is the only real standout. The swell jumps to 6 feet from the north, period 7 seconds. The morning is blown out, but the afternoon cleans up with a light cross-offshore breeze from the WNW at 10 km/h. The combined energy hits 400 – that’s a proper push. But at 6 feet, this is for experienced surfers only. It’s not the ideal direction, but if you’re an expert looking for power, the Saturday afternoon (29th) is your only shot.
After that, it drops back to knee-to-waist high, around 2 feet, through the start of September. Winds turn offshore a few times, but the swell is just too small. There’s a stretch of strong offshore winds on the 3rd and 5th, but the waves are tiny or messy.
The second week of the forecast is dead. From the 4th of September onward, it’s mostly flat or blown out, with a pulse of 5 to 6 feet on the 9th, but with strong cross-onshore winds making it choppy.
Honestly, save your energy. There’s one window on Saturday the 29th afternoon for experts only. The rest is a washout. Water temp is normal for this time of year, but that doesn’t help when there’s nothing to surf.
Stay patient. 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.
