The Lowdown

G’day, Rusty here. Let’s cut to it – the next 16 days at Mushrooms are a test of patience. This is an advanced reef break, exposed and usually consistent, but the first week is mostly a washout. The good stuff is hiding in the second week, so don’t get discouraged.

The outlook starts on Monday, August 17th, but it’s ugly. We’ve got a 5ft SSW groundswell with a very long 16-second period and strong energy (1901). Problem is the wind is screaming from the SE at 25 mph, cross-shore and messy. This reef will be a mess of cross-chop. Tuesday the 18th is worse: 10ft S swell, 10-second period, energy through the roof (3308), and that 22–25 mph cross-shore wind just ruins it. Wednesday the 19th is still 8ft with strong wind. Honestly, if you’ve got a kite, this is more your playground than a surfboard.

Thursday the 20th shows a tiny break – swell drops to 5ft from the SE, 9-second period, energy down to moderate (857). Wind eases to 12 mph from the ESE, cross-offshore, and it’s clean. That’s a marginal call – maybe a sneaky session, but nothing special. Friday through Sunday (21st to 23rd of August) is small – 3ft to 5ft SE swell, light to moderate cross-shore winds, energy dropping as low as 160. Not worth the paddle.

Monday the 24th of August sees a tiny 2ft SSW groundswell with a very long 19-second period, but it’s weak (296) and cross-shore. Skip it.

Now, Tuesday the 25th of August is the first standout. Morning session: 4ft SSW swell, very long 15-second period, and the wind goes glassy – NE at 3 mph. That’s dead calm. Energy is moderate (964), and the wave comment says “expect very good surf conditions.” This reef will love that long-period groundswell – it’ll wrap in with shape. Crowds are possible though. The morning is the real winner.

Wednesday the 26th of August keeps it going: 7ft SSW swell, 16-second period, strong energy (1919). Wind is light SE at 3 mph, just a slight ripple. Clean enough for a ripper session.

But Thursday the 27th of August is the standout of the whole run. Morning: 7ft SSW, 15-second period, and the wind is SW at 3 mph – straight offshore. That’s perfect for a reef. Energy is strong at 1872. The afternoon gets even bigger – 8ft SSW, 14-second period, energy cranked to 2541. The catch? The forecast says it might be too big for this break – expert territory only. If you’ve got the nerve, this is it.

Friday the 28th of August morning still has 8ft S swell, 13-second period, energy 2454, with a light W wind cross-onshore. Also flagged as possibly too big. Afternoon the wind picks up and it turns poor.

From Saturday the 29th through to Tuesday the 1st of September, the swell fades back to 4ft to 6ft SE/SSE, with periods from 10 to 13 seconds, and moderate to fresh cross-shore winds. Some mornings might be okay, but nothing worth planning around.

Bottom line: first week is a bust unless you kite. The real action starts Tuesday morning, August 25th, with glassy 4ft SSW groundswell – that’s your cleanest bet. For size and power, Thursday morning, August 27th, offers 7ft with offshore wind, but it’s experts only. Crowds are a possibility, but on those days, it’ll be worth it.

Stay wet, Rusty.

Information about the Mushrooms Surf forecast

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