The Lowdown
G’day, Rusty here. Let’s talk about Long Beach.
It’s a sandbar spot that breaks pretty reliably, but it’s sheltered from the swell, so it needs a good push from the southwest. Water temp is about what you’d expect for this time of year.
The first real go is Thursday the 10th, with an 8ft swell from the SW, 14-second period, and a clean offshore breeze. The combined energy is solid (2590), and it’s excellent for experienced surfers. That’s the standout – a proper groundswell, clean, and plenty of juice. Not for beginners, as it’s over 5ft. Thursday afternoon drops to 8ft, but still offshore and clean.
Friday the 11th and Saturday the 12th are washed out with strong cross-off winds. Sunday the 13th shows some life: the morning is marginal with a 6ft SW swell, but Sunday afternoon has a 6ft SW swell and almost glassy conditions – “expect very good surf conditions.” That’s a quiet gem.
Monday the 14th is rubbish with onshore wind. Tuesday the 15th is a mess with strong cross-onshore. Wednesday the 16th has a big 12ft SW swell, but it’s only for experts and the wind is cross-off, so it’s a handful.
The real gold is Thursday the 18th and Friday the 19th. Thursday morning has a 7ft SW swell, 15-second period, light cross-off wind, and excellent conditions for experienced surfers. Friday morning and afternoon are even better – 8ft to 8ft SW swell, 15-second period, and gentle-to-moderate offshore winds. Clean, powerful, and lined up. The crowd can be around often, so get in early.
The second week is hit-or-miss. After the 19th, it gets blown out for a few days. A small window on Wednesday the 23rd with clean 5ft to 4ft SE swell, but it’s on the small side. The final note is Friday the 25th, with a 5ft SW swell and a gentle offshore – a nice clean-up set.
Best bet: Thursday the 10th morning for the big clean SW swell, and Friday the 19th for the consistent offshore run.
Rusty out.

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.
