The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Long Beach over the next couple of weeks.
We start off with a quiet beginning, but there’s a real pulse of energy building. The first few days are not the main event, but a solid warm-up. The water temp is sitting at 59°, which is a touch below average for this time of year, but nothing to shiver about.
The first real window of opportunity kicks off on Friday, July 31st. The morning has some clouds, but a light cross-offshore breeze from the SE at 6 mph is keeping things clean. The swell is a tidy 4 ft from the SW with a long 12-second period. The energy is moderate (532). It’s a solid, friendly wave for an intermediate. The afternoon stays clean with a similar vibe.
Saturday, August 1st is where it gets sweeter. The morning is glassy – a dead calm with an ENE breeze at just 3 mph. The swell bumps up to 4 ft from the WSW, with a long 14-second period pushing the energy up to 718. This is a standout morning. The combo of glassy conditions and a nice, clean groundswell makes for some of the best you’ll see all week. The afternoon stays clean with offshore winds, though the swell drops slightly.
Sunday the 2nd is a write-off onshore slop, so skip it. Monday, August 3rd is another absolute gem. The morning is glassy again, with a 5 ft swell from the WSW and a 14-second period, but the combined energy jumps to 1069, which is a solid step up in power. This is a true standout morning where the waves will have some real push and shape.
Things get a bit tricky mid-week, with winds shifting and energy dropping. But then we get a monster window for the experienced crew. Thursday, August 6th through Friday, August 7th sees a massive pulse of swell. Thursday morning brings a 15 ft SW swell with a 14-second period, and the energy is huge (8270). A light cross-offshore breeze keeps it clean. This is expert territory only – that size is not for the faint of heart. Friday eases slightly to 12 ft but stays glassy in the morning, offering another incredible day for those with the skills to handle it.
The second week gets messy with strong winds and rain, although there is a brief, clean window on Tuesday, August 11th with a light offshore wind and a 4 ft SSW swell, and again on Thursday, August 13th with a 6 ft WSW swell, clean offshore winds, and solid energy (1224). That Thursday is a good call for the following week, but it’s further out, so keep an eye on it.
Overall, the best on offer is hands-down the glassy morning of Saturday, August 1st for a clean, fun intermediate wave, and the massive, clean swell of Thursday, August 6th for the experts.

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.
