The Lowdown
Alright, grab your board, let's look at what's coming up around here. I'm Rusty, and I've been staring at these charts. The next couple of weeks is a bit of a mixed bag, with a long flat spell to start before things get a little more interesting.
The water temperature is sitting right around 59°, which is pretty much normal for this time of year – no surprises there.
The start of this forecast is a tough one for surfers. From Wednesday the 19th to the end of the month, it's a desert out there. The surf is tiny, under 2 feet, and the wind is all over the place, mostly sideshore or onshore. The energy is weak, with readings like 11 and 36 – just not enough to get excited about. There's a little bump on the 23rd, but it's a messy 3-foot NW windswell with a period of just 4 seconds and a cross-onshore wind. That's a no-go.
The real story starts to change on the 29th of August. The morning of Saturday the 29th is still a bit messy with a cross-shore wind and a 4-foot swell, but the afternoon is where it's at. The wind swings cross-offshore from the WSW, cleaning up a 5-foot swell from the NE. The energy is solid at 236 (moderate) and the 8-second period should give it some shape. This is the best window we've seen in a while. Then Sunday the 30th gets messy again.
Now, there's a couple of interesting days in the first week of September. The morning of Tuesday the 1st of September looks promising at Langs beach. The swell is a clean 3 feet from the ENE with a 10-second period (groundswell) and the wind is cross-offshore from the SE. The energy is 230 (moderate). It's a good combination. The afternoon is a write-off though, with a strong breeze ruining it.
The real standout, the one I'd be circling in your calendar, is Saturday, 29th of August afternoon. It's the only session in the whole 16 days where the conditions line up properly. The 5-foot NE swell, with that clean cross-offshore wind, should make for some fun, punchy waves at Langs beach. Just keep in mind that the crowds there can be a problem *sometimes*, so get out there early or late. It's a fairly consistent spot, so you'll get waves.
After that, the surf drops back down again and fades out. The 31st of August has a 7-foot NNE swell, but the period is a short 6 seconds and the wind is onshore, making it a messy, blown-out proposition. The 1st of September morning is the only other decent option, but the 29th is the clear winner.
To sum it up: there's a long, flat gap from now until the 29th of August. That Saturday afternoon is your best bet by a long shot. The 1st of September morning is worth a look if you're keen, but don't expect magic. After that, the forecast runs dry again.
Rusty.

Information about the Langs beach Surf forecast
The above surf forecast table for Langs beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Langs beach can be found by selecting the local surf guide option on the grey menu. Our Langs beach 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 (Langs beach) 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 Langs beach 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.
Langs beach is 41 km (25 miles) from the city of Whangarei. If you plan a holiday in Northland, look for hotels and other accommodation in Whangarei. Whangarei has rooms for a wide range of budgets as well as car hire and transport links.
