The Lowdown
Imperial Version
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. We've got a long, flat spell ahead.
Over the next 16 days, Tawharanui (beach and reef) is the only spot on the cards, and it’s basically a write-off for the first week and a half. The combined swell energy is nothing but two-digit numbers, mostly in the teens to low 20s (e.g. 58, 21, 29), which is just weak. The swell is tiny, never getting above 2ft, and the period is all over the place from short 6 seconds to long 13 seconds, but with no size to back it up those long periods just mean long lulls between closeouts. It’s just poor surf conditions start to finish. Winds are offshore from the SW a lot of the time, which would be great if there was any swell to clean up, but there isn’t. The water temp is 59°, which is about average for this time of year.
Now, there’s a tiny flicker of hope right at the tail end. On Thursday the 24th of September, we finally see some glassy conditions in the morning with a little 3ft pulse from the NNW. The score is still a 1/10, and it’s "surfable waves but very ordinary conditions", so don't get your hopes up for anything epic. The energy climbs to 59, which is still weak but at least it's not the teens. Winds go glassy early, then a light cross-off in the arvo. That morning session might be your only chance to get wet with something that isn't totally flat, but it's only for beginners. After that, it’s back to nothing again.
Honestly, the whole setup is so weak for so long that if you’re after a thrill, this looks more interesting for a kite than a surfboard. Not much else to say. It’s a blank run, plain and simple. Forecasts can change, but right now, this is a long stretch of no surf.
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.
