The Lowdown
Alright, let’s break this down for Tawharanui. The next couple of weeks are looking pretty flat, with only a few small windows worth getting wet for.
The first real chance rolls in on Monday, 10th of August. The morning’s your best shot: a 4ft swell from the north with a 8-second period, and the wind is light out of the WSW at 6 mph, giving you a clean, offshore breeze. The combined swell energy is moderate at 226, so there’s some push behind it. It’s a beach and reef break here, exposed to the north-east, so that north swell is working. It’s fairly consistent, so you’ll get a few. The water temp is about average for the season. This is the standout session – clean, shoulder-high waves for the intermediate crew.
The afternoon of Monday 10th goes glassy with a 4ft north swell, but the conditions are just ordinary, not great.
Tuesday 11th is a total loss with strong onshore winds, and Wednesday 12th offers a 4ft north swell in the morning with a clean cross-off breeze from the WNW at 9 mph, and again in the afternoon it goes glassy with a 4ft north swell. The wave energy is moderate (175 and 148), and the conditions are clean but nothing special. Surfable, but not a classic.
Thursday 13th morning is glassy with a 3ft north-northeast swell, but it’s weak with only 86 energy. The afternoon turns onshore and messy.
From Friday 14th onwards, it goes to hell. The swell picks up, but the wind howls onshore, with heavy rain and a messy, lumpy ocean. The combined energy hits 600+ on the 14th, but with the wind onshore, it’s a churned-up mess. This beach and reef setup is more interesting for the kite surfers than paddle surfers in those conditions.
The second week is a flat spell. From the 15th to the 22nd of August, the swell drops to under 2ft, and the wind is often cross or onshore, with only a few glassy moments. The energy is low, mostly under 100. The morning of the 16th is glassy but only 1ft, and the 19th and 20th have some clean or glassy conditions but with tiny, weak swell. Nothing to ride.
So, the only real highlight is Monday 10th August morning at Tawharanui. Clean, chest-high north swell with a light offshore wind. It’s not the best of the year, but it’s all we’ve got. The rest is flat, windy, or a mess. Stay patient.

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.
