The Lowdown
Alright, let’s talk Fourth Beach. It’s a 16-day run, and we’re starting slow. The water’s sitting at 62°, which is about average for this time of year.
The first real chance is Monday, August 3rd. It’s marginal, with a 5ft swell from the SSW, a 15-second period, and a cross-off wind from the NE at 9 mph. The energy is moderate at 906. Not a standout, but it’s there.
Tuesday, August 4th, is mixed. Morning has a similar 5ft SSW swell, but the wind is stronger from the NW at 16 mph, and the energy is 1633. Still marginal. The afternoon gets bigger to 7ft, but the wind swings onshore from the SSW, making it a mess.
Now, Wednesday, August 5th, is where it’s at. The morning is clean, with a 7ft SW swell, 16-second period, and a cross-off wind from the WNW at 9 mph. The energy is strong at 2201. The absolute standout is Wednesday afternoon. The wind goes glassy, dead calm from the SSE at 3 mph, and the swell is 10ft from the SSW with a 16-second period. The energy is very strong at 4161. This is for experts only—over 8ft is big-wave territory. Clean, powerful, and long lulls between sets.
Thursday, August 6th, stays solid. Morning has an 8ft SSW swell, 16-second period, and a cross-off NW wind at 6 mph. Energy is 3785. The afternoon has a light offshore from the NNW, keeping it clean. This is a close second.
Friday, August 7th, is a step down. The swell is still 8ft, but the wind turns messy. Saturday, August 8th, is a write-off—strong winds and a massive 15ft swell. The energy is 7908, but it’s blown out. More for kite surfers.
Sunday, August 9th, through Tuesday, August 11th, sees huge swell in the 13ft to 20ft range. The energy is in the thousands, but the comments say the swell is too big for this break. Unless you’re a pro, stay out.
We get a lull on Friday, August 14th, with a 6ft swell, but it’s onshore.
Then, the second week brings a good run starting Saturday, August 15th. The morning is glassy, with a 8ft SSW swell and a 17-second period. Energy is 3604. Clean, but long period means it’s best at the point.
Sunday, August 16th, has a moderate offshore wind from the N at 12 mph, with a 7ft SSW swell. Energy is 2597. Clean. Monday, August 17th, is similar, with a 7ft swell and offshore winds. Tuesday, August 18th, has a fresh offshore from the NNW, with a 5ft swell in the morning, building to 6ft in the afternoon. Good, clean waves for experienced surfers.
The true standout is Wednesday afternoon, August 5th. Glassy, 10ft SSW groundswell, very strong energy. The second best window is from Saturday, August 15th, through Tuesday, August 18th—consistent and clean.

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.
