The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way for Fourth Beach.
The next 16 days start off slow with only marginal conditions and a lot of wind, but there’s a real standout window around the 21st and another towards the 25th that are worth circling in the calendar.
The surf starts with a mix of moderate and onshore winds, which means a bit of chop. The swell energy on Sunday the 13th is moderate (960). Early Monday the 14th, the swell jumps up to 7 ft from the SSW with a period of 13s, but it’s cross-on with 12 mph winds, so the quality is rough. Monday afternoon sees the swell hit 10 ft from the SSW, but with a 19 mph cross-on wind and lumpy conditions, that’s one for the kites only. Through Tuesday the 15th and Wednesday the 16th, the swell sits around 6 ft to 8 ft, but the winds are still messy.
The first real highlight comes Thursday the 17th. Morning brings a clean 4 ft SSW swell with a 15s period and a moderate offshore wind from the north at 16 mph. The water temp is 62°, which is about average for the time of year. It’s a clean session, and with moderate wave energy (661), it’s a nice, manageable size. Thursday afternoon stays clean with a light 4 ft SSW swell and offshore 12 mph winds from the NNE. This is the best clean window in the first week.
Friday the 18th morning is still clean at 4 ft with a 13s period from the SSW, but the wind swings cross-off from the NW at 9 mph, so the quality holds up. By afternoon, the wind turns cross-on and the surf drops to 3 ft with a long 16s period, but the conditions go poor.
Saturday the 19th is a write-off. Near gale-force winds from the WSW at 37 mph and a cross-shore mess. Sunday the 20th sees a solid 8 ft SSW swell return, but the wind is cross-on, making it choppy and rough.
Now, here’s the standout. Monday the 21st morning delivers a 8 ft SSW swell, 15s period, and a clean offshore wind from the NNW at 16 mph. This is excellent surf for experienced surfers. The wave energy is strong (2560), and the offshore wind will hold the face smooth. This is the best session in the whole outlook. The afternoon goes cross-on, so get in early.
Tuesday the 22nd has a 8 ft SSW swell with a very long 16s period, but morning winds are light cross-on, just ripples. The energy is very strong (3524). This is a big, powerful groundswell, best at a point or reef, but at Fourth Beach, the long period might make it break a bit too straight. Still, for the experienced crew, it’s worth a look.
Wednesday the 23rd stays big at 8 ft, but the wind is onshore or cross-on, making it lumpy. Thursday the 24th morning sees a slight improvement with cross-off winds from the ENE at 9 mph and a 8 ft SSW swell with a 16s period, giving clean conditions again.
Then, the second standout comes Friday the 25th morning. A solid 7 ft SSW swell, 15s period, and a clean offshore wind from the NNE at 16 mph. Excellent conditions for experienced surfers. The energy is strong (2090), and the face will be pristine. After that, the weekend turns messy again with strong cross-on winds and big, lumpy surf, closing out the outlook with poor conditions on the 27th and 28th.
Bottom line: Thursday the 17th and Friday the 18th mornings are your clean, smaller windows. Monday the 21st morning is the top-tier session. Friday the 25th morning is another solid clean day. The rest is mostly blown out or too rough for a good paddle.
Rusty out.

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.
