The Lowdown
Alright, let’s get real about Long Bay Reef. I’ve looked at the next couple of weeks, and honestly, it’s a tough stretch. There’s a big old gap of nothing before we even get a sniff of a wave. We’re looking at a run of flat, clean days through the 8th. It’s going to feel like the ocean just took a holiday.
Then, around the 9th, we get some tiny, short-period windswell, but the north wind is going to have it all chopped up. Not worth getting wet for. That’s not surf; that’s just noise.
The first real sign of life shows up on the 12th. The swell starts to build a little, with waves around 4ft. The energy reading finally gets past that hundred mark at 131, so there’s some push to it. The wind is a light cross-offshore from the west-northwest, which keeps the surface reasonably tidy. This is the standout of the entire window for me. It’s not huge, but it’s clean and rideable, and for a spot that’s this sheltered, you take what you can get. The period is only 7 seconds, so it’s a bit crumbly, but it’s surfable.
The 13th goes flat again, and we’re back to waiting. The 15th has a tiny pulse, but it’s not worth the paddle.
The next notable push comes on the 16th. We see a bit more size, up to 4ft in the afternoon, with a longer period of 9 seconds. The energy jumps up to 227, so there’s some real power behind it. The wind is a cross-offshore from the southwest, so it should be clean. This one looks like it could have a bit more shape to it, a bit more punch. That’s your second option.
After that, things get weird. Big winds from the south and west kick up, but the swell dies. We see some poor quality, short-period junk that won’t break right on this reef. It’s looking more like a kite-surfing wind farm than a surf spot. The period drops back down to 3 seconds, and there’s just no energy. It’s over.
So, bottom line: mark the 12th as your best bet. It’s the cleanest, most consistent option we have. The 16th is a runner-up, but it’s a bit further out, so don’t book your flights yet. The rest is a write-off. It’s a real dry spell for this stretch of coast, but that’s how it goes sometimes. You gotta be patient.
Stay stoked.

Information about the Long Bay Reef Surf forecast
The above surf forecast table for Long Bay Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Long Bay Reef can be found by selecting the local surf guide option on the grey menu. Our Long Bay Reef 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 (Long Bay Reef) 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 Long Bay Reef 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.
Long Bay Reef is 13 km (8 miles) from the city of Northshore. If you plan a holiday in Auckland, 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.
