The Lowdown
Alright, listen up. Tawharanui’s got a rough patch ahead. Water temp’s about 59°, which is normal for this time of year.
First real shot is Friday the 17th in the afternoon. Swell’s only 1ft from the east, with a long 17-second period. That’s groundswell, but it’s tiny. Combined energy is weak (92). Wind’s blowing offshore from the southwest at 13 mph, so it’s clean. For a beginner, you can paddle, but don’t expect much.
Saturday the 18th is the same story: 1ft in the morning, 1ft in the afternoon. Winds stay offshore, glassy. Energy drops to 75 then 41. Clean, but knee-high.
Then it goes dead. From Sunday the 19th through Thursday the 30th, the surf is mostly poor. Swell barely hits 0.7ft, 0.3ft, or nothing. There’s a little bump on Tuesday the 21st with 4ft of windswell, but the period is a short 5 seconds and the wind is cross-onshore, choppy. Energy hits 71, but it’s a mess. That’s a full week-plus of barely anything.
Friday the 31st is the best of the bunch. Swell is 3ft from the east, period 8 seconds, energy up to 95. Winds are cross-offshore from the west at 19 mph, so it’s clean. Still small, but it’s the closest thing to a surfable day. Saturday the 1st of August follows with 1ft and clean cross-off winds, but again, ankle to knee-high.
The standout? There’s no real standout. If you’re itching, Friday the 31st has the most energy and cleanest conditions, but it’s a longboard or foil day. Crowds are often at Tawharanui, but with waves this small, it should be quiet.
The break is beach and reef, exposed to the northeast. The optimum swell direction is NE, and we’re mostly getting east and east-northeast, so direction’s okay. But the size is a total bust.
Bottom line: long spells of nothing, and the best day is still tiny. For kite surfers, the windier days with 4ft and cross-onshore might be fun, but for paddle surfing, it’s a rough stretch.

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.
