The Lowdown

Right off the bat, Saturday the 15th is looking like a proper little gem to kick things off. Long Beach is serving up a clean 6ft of WSW swell with a 14-second period, and the wind is dead glassy out of the southeast. That's the sort of morning you paddle out for. The water is sitting at 57°, which is a bit colder than normal for this time of year, so you'll be wanting that hood or a good thick suit. The energy is solid, coming in at 1261, and it just feels like the ocean’s got some push to it. The sandbar is holding its shape. It's not pumping, but it's clean and fun. That afternoon it bumps up to 7ft with a light cross-off, staying just as good. This is the standout of the first week, no doubt.

Now, don't get too excited for Sunday the 16th. The north wind swings in and ruins the party. It's 7ft but blown out with onshore wind. That's a write-off. Monday the 17th is still messy in the morning with more onshore wind, but the afternoon flips it. The wind swings southwest, a cross-off at 6 mph, and that 8ft swell cleans right up. The energy jumps to 2555, and it’s solid. This is good for experienced surfers for sure. Tuesday the 18th is a bit of a mixed bag—morning has some cross-off but it's lumpy, and the afternoon jumps up to a raw 10ft, but the wind is up to 19 mph, making it a bit of a grinder.

The middle of the week from the 19th to the 20th is just average. We're seeing 8ft to 8ft of SW swell with cross-off winds, but it never really clicks. It's clean, but just sort of ordinary. The energy is moderate, nothing special.

Now, Friday the 21st brings a new dawn. The swell drops a bit to 6ft, but the wind goes dead glassy again in the morning. It’s a clean 732 energy. It’s not big, but it's small and clean. But that afternoon the wind turns cross-shore and it gets messy, so make the most of the morning.

Hold on to your board for Saturday the 22nd. We get a massive pulse. The swell explodes to 15ft in the morning, blowing out to 16ft by the afternoon. The energy is off the charts at 6502 and 9398. But the wind is onshore and howling at 19-22 mph. It's a total washout for paddling. If you've got a kite, this is your day, because that’s a full-on beast. Sunday the 23rd is still big, 12ft to 13ft, with the energy over 8900. The wind is cross-off but fresh, so it’s still a heavy, expert-only affair. This is pure power.

Into the second week, things get a bit more manageable. Monday the 24th is a solid 10ft with cross-off winds, but it's still a sizeable, demanding day. The standout of this stretch looks like Tuesday the 25th. The swell eases to 7ft in the morning, then 5ft in the afternoon, and the wind goes proper offshore out of the south at 12 mph. The energy is still respectable at 1806. That afternoon session is going to be clean, glassy, and fun for everyone. That’s the one to circle.

Wednesday the 26th turns ugly again with onshore winds and 8ft of lumpy swell. Not good. Thursday the 27th is better, but ordinary, with clean but average 8ft to 8ft surf.

Then, just when you think it's all over, Friday the 28th is an absolute sleeper hit. The morning is completely glassy with zero wind and a clean 10ft of SW swell at a 14-second period. The energy is pumping at 4036. That's an epic, expert-level morning. The afternoon drops to 7ft but stays clean with a light cross-off. Two great windows on one day. That's the other big standout—trust me on that one.

The final weekend, the 29th and 30th, fizzles out. Saturday is blown out with onshore wind, and Sunday has strong cross-off winds but the swell drops right off to 5ft to 5ft. There's still some energy but it's just not worth the hassle with that wind. It’s a fade-out.

So, to sum it up, you've got Saturday the 15th and Friday the 28th as your two true standout days for clean, quality surf. The 22nd and 23rd are for the brave or the kites, and Tuesday the 25th is your best bet for a fun, less intimidating session.

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.
