The Lowdown
Alright, Rusty here again. Let’s break down Sandy Mouth for the next couple weeks.
First off, we’ve got a rough week ahead. From Monday the 14th through Saturday the 19th, it’s just poor. The wind is cross-on and onshore from the SW and WNW at 12 to 19 mph, and the surf is choppy and messy. Swell is running 3 ft to 6 ft from the west, but the wind’s trashing it. The wave energy is moderate, peaking at 746 on Wednesday morning, but you wouldn’t know it. Stay home.
Sunday the 20th is still poor. The swell drops to 3 ft, wind goes light onshore in the morning and light offshore in the afternoon, but it’s still not worth it.
Now, Monday the 21st, things finally clean up. The wind goes light offshore from the SE at 3 mph. The west swell is 2 ft with a 10-second period. Wave energy is weak at 94. It’s surfable, but very ordinary.
Tuesday the 22nd morning is your best call. Wind goes glassy from the ESE at 3 mph. Swell holds at 3 ft from the west, but the period bumps to 12 seconds, giving it more push. Energy is moderate at 171. It’s small, but clean. The water is 65°, which is much warmer than normal – 4° above average. You might not need a full winter suit.
Wednesday the 23rd morning is glassy again from the ENE at 3 mph, but the swell drops to 2 ft with a 9-second period. Energy is weak at 80. Clean but tiny.
Thursday the 24th morning is glassy from the south, with a 3 ft west swell at 10 seconds. Energy is moderate at 117. Marginal.
Friday the 25th and Saturday the 26th mornings are clean with light offshore winds, but swell is tiny at 2 ft to 3 ft. Not much to write home about.
From Sunday the 27th, the swell tanks. We’re looking at 0.7 ft to 1.0 ft waves. Offshore winds keep it clean, but there’s nothing to ride. On Tuesday the 29th, a 2 ft west swell shows up with a very long 14-second period and moderate energy at 139, but it’s still too small.
So, the standout is Tuesday the 22nd morning. Glassy, clean, and that 12-second period gives the small swell some life. It’s not a big day, but it’s the only real quality window in this whole run. After that, you’re waiting.
Rusty.

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