The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Manchester Beach.
To be straight with you, the next week and a bit is a bit of a write-off. We've got a real rough patch of onshore winds and messy swell. Monday the 14th and Tuesday the 15th are a total no-go with strong onshores and lumpy, short-period NW swell. The water is sitting at 57°, which is a good bit colder than what you'd expect for this time of year, so you'll want a thick steamer if you were even thinking of getting in, but honestly, don't bother. This first run of poor conditions stretches all the way through to the 20th. There's a little flicker of hope on the morning of Thursday the 17th with a light southerly cross-offshore wind and a clean-looking 6ft NW swell, but it's inconsistent and the crowds can be around. It might be a sneaky window if you're desperate, but it's hardly a standout.
Now, if you can hold out, things start looking much better. The real gem in this forecast is Tuesday the 22nd. We've got a solid 7ft to 8ft NW groundswell rolling in. The period pushes up to 10 seconds, so there's some decent energy behind it (combined energy of 1620). The wind is the clincher here – glassy in the afternoon with a light WSW breeze. For a beach break, that long period can make it a bit straight, but with clean conditions and that size, it'll be offering up some proper waves. This one is for the experienced crew though; at 8ft it's not a beginner's day. Keep an eye on the crowds too, it can get busy.
Wednesday the 23rd morning still looks fun with a 5ft NW swell and clean cross-offshore winds, a good follow-up session if you're around. After that, the surf drops right off into the end of the month, with a lot of small, weak, and wind-affected swell.
So, to sum it up: the next week is a bust. But mark your calendar for Tuesday the 22nd. That's your day. Glassy conditions, a solid groundswell, and proper waves for those who know what they're doing.
Rusty.

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