The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next 16 days. I’ll be straight with you – it’s a pretty bleak stretch, so keep your expectations in check.
Right off the bat, we’ve got a long gap of nothing worth paddling out for. The first real surf recommendation doesn't show up until Monday, July 27th, which means more than a week of flat, small, or just plain ugly conditions. From Wednesday the 15th through Sunday the 26th, it’s all poor surf with tiny waves, weak energy, and messy winds. There’s a few morning sessions with clean-ish wind, but the swell is just too small and weak to bother with. The combined energy during this period is in the low double digits, often under 30. That’s barely a ripple.
The one and only standout – and I use that term loosely – comes on Monday, July 27th at Sandy Mouth. The morning sees a glassy start with a light WNW breeze, and the swell is a modest 2ft from the W at 8 seconds. The combined energy is still only 80, which is weak, but it’s the best we’ll see. The water temp is a notable 64°, which is a solid 4° warmer than usual for this time of year – that’s a real treat for the skin. The afternoon gets even better: glassy calm with zero wind, and 2ft from the W at 9 seconds, energy 61. It’s surfable, clean, and about as good as it’s going to get. Don’t expect any power, and the crowds are sometimes an issue here, so you might have company.
After that, Tuesday the 28th starts with a clean but onshore wind and a small 2ft swell, and the quality drops right back down. The long-range stuff around the 29th and 30th sees a slight bump in size – up to 4ft from the W on Thursday the 30th – but with short period (6-7 seconds), onshore winds, and choppy conditions, it’s just not worth the effort. The energy does climb into the triple digits (114 to 136), but it’s messy and blown out.
Honestly, if you’re not a die-hard, give it a miss. The blank run is long, but when it’s this flat in this area, it’s not unusual. Keep an eye on the forecasts, but for now, Monday the 27th is your only real shot.
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.

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.
