The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer.
Honestly, mate, it’s a grim stretch for Long Beach this time around. The whole 16-day window is a write-off for decent surf. We’ve got swell – sizes bouncing between 3 ft and 7 ft – but the problem is the wind. It’s stuck on a relentless cross-onshore flow from the east and east-northeast, mostly in the 15 to 22 mph range. That’s blowing everything out, making it lumpy, choppy, and just plain messy. The combined swell energy sits between 83 and 465, so there’s some moderate juice in the water, especially around Thursday 17th September afternoon when it hits 7 ft from the east with 465 of energy. But with that cross-on wind, the waves are going to be a jumbled-up mess, not fun to paddle into.
Every single report says “poor surf conditions.” There is no standout day. No moment where the wind eases or shifts offshore. It’s just a long, frustrating run of onshore slop. If you’re desperate, the smallest days (around 20th and 21st September) with swell down to 3 ft might be the least intimidating, but the wind is still ruining any shape. For the bigger days, like around 6 ft to 7 ft, that’s too much for a beginner and just ugly for anyone else. Honestly, with that steady cross-on breeze and a beach setup, this looks more interesting for kite surfing than a paddle session. The inconsistency of the break just adds to the frustration – it’s not going to be worth the paddle out.
Long Beach is usually better than this. It’s a quiet spell, but forecasts can turn. Hang in there.
Rusty.

Information about the Long Beach Surf forecast
The above surf forecast table for Long Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Long Beach can be found by selecting the local surf guide option on the grey menu. Our Long 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 (Long 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 Long 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.
