The Lowdown
Alright, Rusty here, breaking down the next couple of weeks for Long Beach.
Water’s sitting at 60°, which is right about average for this time of year – nothing out of the ordinary.
We’ve got a slow start. Sunday and Monday are messy, with a cross-onshore breeze and a chunky, choppy wave. The energy readings are high (1259 dropping to 419), but the quality is poor. This setup actually looks more interesting for a kite than a surfboard.
The first real standout is Tuesday, 21 July. The morning is glassy – dead flat calm – with a solid 8ft SSW groundswell. The period is a long 14 seconds, so the waves have real punch and nice long lulls. The combined energy is massive (2427). This is expert-only territory: big, clean, and powerful. Wind stays offshore in the afternoon, too. This is your best bet.
Wednesday, 22 July is a step down – the wind swings cross and cross-on, making things a bit lumpy. Still a fun 7ft SW swell, but not the same quality.
Then on Thursday, 23 July afternoon, the wind goes glassy, and the swell jumps to 12ft from the SW with a very long 16-second period. The energy reading is enormous (5868). That’s a proper groundswell – clean, powerful, and best suited for reefs or points. For the experienced crew, it’s a must.
Friday, 24 July morning holds similar size and quality – 12ft SW, glassy, with a 14-second period (4968 energy). Again, expert-only.
From Saturday the 25th onward, the wind picks up, staying cross-off and fresh. The swell stays solid, but it gets challenging. Late July into early August is mostly poor, with onshore winds and lumpy surf. A potential window on 30 July shows a clean 7ft SSW swell and light offshore wind, but it’s a long way out.
The first week of August is mostly a write-off. There’s a small glimmer on Monday, 3 August, with a clean offshore breeze and a 3–4ft SW swell, but it’s small and mellow.
Overall, the standout windows are Tuesday 21 July and Thursday 23 July. If you’re experienced and hungry, those are the days to circle.
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.
