The Lowdown
Alright, Rusty here, giving you the lowdown in Imperial for the same spot.
The big story is a whole lot of Southern Ocean groundswell stacking up. Fourth Beach is the only break we're looking at, and it's an advanced spot that handles SW swell. Water temp is 61°F, which is about average for the time of year.
The action starts Thursday afternoon, August 13th. Swell is a thumping 12 ft from the SSW with a crazy long 17-second period. The wave energy is massive (7305). The wind is light from the south. But honestly, this is too big – only for the truly mad.
Friday morning, August 14th, is the first real standout. The swell drops to 10 ft, still from the SSW with a 16-second period, but the wind goes NE at 6 mph, giving us a clean, cross-off breeze. Energy reads at 5076. This is for experienced surfers only.
Saturday morning, August 15th, is a bit more user-friendly for the advanced crew. Swell at 7 ft from the SSW with an offshore NNE wind at 9 mph. That’s clean. Period is 14 seconds, energy 1874. Good morning window.
Monday, August 17th, afternoon session is a gem. Swell at 6 ft, 18-second period, a clean offshore north wind at 16 mph. That’s a powerful, clean wave, but the really long period means the sets will be fat and a bit straight at a beach break. It’s for experts.
Tuesday, August 18th, is shot. Strong WSW winds at 25 mph with rain and a cross-shore mess.
Thursday afternoon, August 20th, is a glassy highlight. Wind goes SSW at just 3 mph with a 8 ft SW swell. That’s clean, peaky faces.
For the second week, things stay consistent. Saturday, August 22nd, morning is a standout: a 10 ft SSW swell, 15-second period, and a light NNW cross-off breeze at 6 mph. Energy is 4498. That’s a huge, clean session for the elite. And Thursday morning, August 27th, looks magic with a 8 ft SSW swell, 16-second period, and a light NNW cross-off. Energy is a massive 6182.
So, for the crew who can handle it, the best bets are Friday morning August 14th and Saturday morning August 22nd. The rest is either too big or too messy. The Thursday the 27th morning is a potential classic if the long-range model holds.
Rusty.

Information about the Fourth Beach Surf forecast
The above surf forecast table for Fourth Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fourth Beach can be found by selecting the local surf guide option on the grey menu. Our Fourth 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 (Fourth 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 Fourth 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.
