The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Sandy Mouth over the next couple of weeks.
First up, I gotta be straight with you – the first few days are a bit of a write-off. The swell is tiny and the wind is messy. We've got some cross-onshore slop, and the wave energy is weak (81). It's not worth paddling out for, unless you're desperate for a float. The water temp is feeling about average for this time of year, nothing wild there. This quiet spell stretches on with poor conditions, but hang tight, because there's a glimmer of hope later on.
The only standout window I see is on the morning of Wednesday the 16th. That's when things finally line up. We'll have a clean 3ft swell rolling in from the WNW, with a 9-second period. The wind will be light and cross-off from the south, keeping the surface glassy. The wave energy bumps up into the moderate range (367). This is the one to circle. It won't be massive, but it'll be clean and fun for a surfer who knows what they're doing. Keep in mind that Sandy Mouth is exposed to the west, so this WNW swell will wrap in nicely.
Outside of that, there's really nothing else worth getting excited about. The rest of the forecast is a mix of onshore winds and lumpy, choppy surf. The combined swell energy gets as high as 1237 on the 7th, but the strong 16 mph onshore wind and 6ft messy swell just won't be any fun to paddle into. That kind of setup with a beach break looks more interesting for the kite crowd than us paddlers.
A couple of other mornings, like the 16th afternoon or the 21st, get close, but the wind swings onshore or the swell drops away. It's a long-range call for the 16th, so don't bet the farm on it, but it's the best we've got.
So, to sum it up: the first week and a half is pretty bleak. Wednesday the 16th morning is your one to watch for clean, smallish waves at Sandy Mouth. The rest, leave it.
Stay frothy.

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.

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.
