The Lowdown
Right, let’s have a look at what’s on the cards for Ansteys. This spot is an exposed E-facing setup, and it does get inconsistent, so we’ve got to wait for the right window. The water temp is sitting about average for this time of year, nothing wild there.
The next 16 days are a bit of a mixed bag, and honestly, there’s a lot of junk to wade through. The first solid window of proper surf doesn’t really show up until the end of the second week. The immediate period is a write-off – strong NE cross-shore winds, lumpy, bumpy, and the swell is just messy. The combined energy is moderate (431) but the quality is poor because of the wind. That carries on through the 10th and 11th with cross and cross-on winds, and the swell stays short-period and chopped. Thursday the 12th drops right off, tiny 3ft to 3ft E swell, weak energy (145), and cross-on zephyrs, barely worth a paddle.
There’s a slight flicker on the morning of the 15th – the swell is 6ft from the E, period 9 seconds, and the wind is a light cross-shore, which cleans it up a bit. The combined energy is moderate (462) and the forecast says marginal, not terrible. It’s the best of a bad lot in the first week, but it’s still a bit inconsistent. The 16th morning has a clean window with 5ft E swell and light onshore breeze, but it’s a marginal call.
Everything then goes wild again. The 17th kicks up a big 8ft S swell with 8-second period, but the wind is a strong cross-shore. That’s big, lumpy, and messy – only for the brave and the experts. The combined energy spikes to 1098 (moderate), but the quality is poor. The 18th and 19th are more of the same – cross-onshore and lumpy, or fresh cross-shore junk.
Then, the standout. The 21st has a monster swell: 8ft from the S, but the period is a very long 18 seconds. That’s a proper groundswell. The combined energy is enormous (3878). The problem is the wind – strong cross-onshore, so it’s going to be a messy, blown-out beast. Only for the most experienced, and the long period at a beach break will make it a straight, angry wall. Better suited to a reef or point, but we don’t have one here.
The real window to watch is the 22nd and 23rd. The 22nd morning has a 6ft S swell, period 14 seconds, with a moderate cross-shore breeze. That’s cleanable, with good energy (1139). The 23rd morning has a 5ft S swell, still 12-second period, but with a fresh cross-shore wind. The afternoon of the 23rd is the best bet: 5ft S swell, 12 seconds, and a cross-off shore breeze, which will groom it nicely. The combined energy is 1082 (moderate), and the forecast calls it marginal but the wind is clean. That’s a session worth chasing, especially if you can get a peak to yourself – it’s inconsistent so the crowd might be light, but it can still get busy.
Given the inconsistency and the long run of poor conditions, a blank run like this is fairly normal for the area. The 23rd afternoon is the one to circle on the calendar. Bigger, longer period, glassy wind – that’s got potential.

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