The Lowdown
Alright, Rusty here, checkin' in with a look ahead at Tawharanui.
To be straight with you, the next couple of weeks are lookin' pretty bleak for a proper paddle. We've got a long stretch of flat, weak junk ahead with very little to get excited about. The first real blip of interest doesn't show up until Saturday the 7th of September, and even that comes with a major catch.
Right now, through the end of August and into the first week of September, it's mostly small, weak, and messy. There's a bump on Saturday the 30th of August with a 3 ft swell from the NNE and a fresh offshore breeze from the WSW, but it's only 8 seconds, and the wave energy is weak (152). Sunday the 31st and beyond just fades into tiny 1 ft to 2 ft dribble with hardly any push. You'd be better off takin' the dog for a walk.
The one standout in the whole run is late Monday afternoon on the 7th of September. We get a serious pulse of energy – a 12 ft swell from the north with a solid 9-second period. The combined energy is 1631, which is strong. The problem is, that's way too much water for Tawharanui. The forecast literally says it's too big for this break. This is expert-only territory, and honestly, the setup looks more interesting for kite surfing than paddle surfing in that kind of juice. The wind is rippin' at 28 mph from the west, keepin' it clean, but that size and power will just close out the beach.
Tuesday the 8th drops back down to 3 ft from the north, but with moderate onshores, it'll be choppy and sloppy again. After that, it's back to tiny, clean but tiny surf all the way through the 12th.
So, the bottom line: if you're an expert, mark your calendar for that massive Monday the 7th, but know it's a beast. For everyone else, this is a blank run. It happens sometimes. Forecasts can change, but right now, the waiting game is on.
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.
