The Lowdown
Alright folks, Rusty here. Let's get into what we're looking at for the next couple of weeks.
Gotta be honest, it's a rough start. The charts are showing a whole lot of nothing for the first week. You're looking at a solid block of days with hardly a ripple. You'll be waiting until the 26th of July before there's even a whisper of a wave worth paddling for. That's a long, dry spell. The water temperature is sitting at a very unusual 69°F, which is much warmer than we'd expect, so at least a dip won't be a shock to the system.
The only real window of opportunity fires up right at the end of the month. On the morning of Sunday, the 26th of July, we finally get a pulse of swell. Mewslade Bay will see some 5ft swell from the WSW, with a period of 6 seconds. The energy is moderate, sitting at 199. The NW wind will be blowing cross-offshore, keeping the surface clean. That's the best we've got, but it's still a pretty average wave. It's a bit dumpy and short-period, so not a classic. The afternoon stays similar with 5ft swell, but the wind swings more cross-shore, so the morning session is the pick.
Moving into Monday, the 27th, the swell drops a touch to 5ft, still from the W, with those cross-offshore NNW winds. It'll be clean, but the energy is dropping. By Tuesday, the 28th, we're back downhill, with 3ft swell and fading fast. The rest of the week is a slow bleed back to flatness. The 3rd of August shows a tiny 0.7ft swell with glassy conditions, but it's barely a ripple.
There's no standout quality here. The best of a bad lot is that Sunday morning, the 26th of July, at Mewslade Bay. It's an exposed beach break, and with the swell being short-period, it won't have much shape. The crowds are listed as "sometimes," so you might have the place to yourself, but honestly, that's more because the surf is poor. No one's getting excited about this one.
Rusty.

Information about the Mewslade Bay Surf forecast
The above surf forecast table for Mewslade Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mewslade Bay 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 Mewslade Bay 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.
