The Lowdown
Alright folks, let's have a look at what's on the cards.
The next couple of days are going to be a write-off, so don't even bother waxing up just yet. We've got a rough Saturday the 5th with a howling 28 mph cross-off wind and a messy 10ft SE windswell that’s just pumping out junk. That clears through Sunday the 6th when the wind drops, but the conditions are still marginal.
The real action starts to build from Monday the 7th. The first standout is shaping up for Monday afternoon at Long Beach. We’re looking at a clean 7ft of swell rolling in from the SW, with a proper 13 second period – that’s got some punch. The wind is a light cross-off, so the face should be pretty tidy. The combined swell energy is sitting at 1396 (moderate), so there’s enough there to get you into some decent ones. It's a sandbar break, and with it being fairly consistent, you won't be waiting around all session, though you might have some company.
Tuesday the 8th morning is a sneaky gem. The swell drops right back to 3ft from the WSW, but check it – the wind is dead calm, glassy. Zero wind. That combined energy is weak at 590, so it's a longboard or a funboard day, but if you want to surf a mirror, that’s your window.
Now, hold onto your leash for the big one. Saturday the 12th morning is a proper standout for experienced surfers only. Long Beach is going to be pumping with a solid 15ft of SE swell. That’s big, mean, and the combined energy reading is 4711 – that’s strong to very strong energy. It’s glassy, calm wind, which is a gift. This is not for beginners; this is for the crew who know what they’re doing.
We hit a bit of a messy patch mid-week with strong onshores, but another strong contender shows up on Wednesday the 16th morning. The swell is a chunky 10ft from the WSW with a 14-second period, and we have a fresh offshore wind cleaning it right up. The combined energy is 3694, so it’s got serious grunt. That’s another day for the experienced crew.
The last real standout to circle is Saturday the 19th morning. It’s going to be glassy again, dead calm, with an 12ft SE swell arriving with an 11-second period. The combined energy is big at 4807. This one is right up there, but it’s over a week away, so keep an eye on the charts.
Water temperature is about average for the time of year, so no nasty surprises there.
The 15th and 17th are looking pretty grim with strong winds and poor surf conditions. The 20th is a write-off with rain showers and a fresh offshore.
So, if I’m picking the best of the bunch: Monday afternoon the 7th for a clean, solid session when the wind eases, and Saturday morning the 12th for the big, glassy bomb set for the experts.
Stay stoked, and keep checking the forecast.

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.
