The Lowdown

Alright, crew, Rusty here. Let’s get straight into it. The next couple of weeks are looking like a bit of a mixed bag, so let’s break it down day by day and see where we can actually get a wave without it turning into a washing machine.

The immediate forecast is pretty lackluster. The swell is small and most of the wind is cross-onshore or choppy, so we're looking at a few days of junky conditions. The energy is in the moderate range, around 761 to 812, but it’s not doing us any favors. Friday and Saturday are write-offs; the swell is around 6ft and 3ft but the wind is messy, and there's a lot of chop. Not worth paddling out for.

We’ve got a real gap here. From Saturday afternoon through to the middle of next week, the surf is just poor. We’re talking about a solid three or four days where the waves are weak, and the conditions are choppy. Sunday the 13th is particularly bad, with poor surf and light cross-shore winds. The energy drops right down to under 500, which is weak.

Okay, now for the first glimmer of hope. On Monday morning, the 14th, we finally get a bit of a window. The wind goes completely glassy at 0 km/h, and the swell is a clean 4ft from the NW with a period of 8 seconds. The combined energy is still moderate at 347, but that glassy conditions is a huge plus. It’s not going to be epic, but it might be worth a paddle if you’re desperate and just need to get wet. That window slams shut by the afternoon when the wind picks up onshore again.

After that, it's more of the same. We’re looking at a few more days of cross-shore winds and small swell. The waves are on the smaller side, around 4ft to 5ft, but it's all a bit lackluster. The periods are short, hovering around 7 to 8 seconds, so it won't have much push. The energy stays weak, ranging from 269 up to 432, so it's more about the wind and conditions than the raw power.

Thursday the 17th morning is another quick look. The wind goes glassy again at just 5 km/h from the ENE, and we’ve got 4ft of NW swell, but it’s still short period. It's another small, clean window, but the energy is down at 235, so think small and soft.

Then we hit another lull. From Friday the 18th through to about Wednesday the 23rd, the swell drops right out. We are talking about 1ft to 2ft. There’s a lot of long-period energy in the water from the SW, but it’s just not showing up on the local banks. This is a classic case of the window being open but nobody coming to the party. The energy drops into the 250 – 400 range, which is weak. Not much to get excited about.

Now, hold on to your boards, because things get interesting towards the end of the window. On Thursday morning, the 24th, the swell starts to fill back in. We’re looking at a modest 3ft from the WNW with a period of 13 seconds. That's a longer period, so it's got a bit more push. The energy jumps up to 663, which is moderate.

But the real standout is Thursday afternoon the 24th. The swell builds to 6ft from the WNW with a 12-second period, and the energy is strong at 966. The wind is only 5 km/h, almost nothing, so it should be pretty clean. This is looking like the pick of the fortnight. It's a bit far out, so treat it as promising, but definitely one to keep an eye on.

The swell backs off a touch on Friday the 25th, down to 4ft but it holds that WNW direction and period. The energy is around 465, which is moderate. There is some cross-onshore wind, so it might be a bit bumpy.

And right at the very end of the forecast, on Saturday the 26th, we have another interesting one. There’s a risk of thunderstorms, with a cross-offshore wind from the south at 15 km/h. The swell is 6ft from the WNW with a 9-second period, and the energy is up at 686. The guidance calls for very good surf conditions, which is exciting. That south wind is going to groom it nicely.

So, to sum it up: don't waste your time for the first 10 days. The standout is Thursday the 24th, and Saturday the 26th looks like a solid backup. Everything else is windblown and small.

Alright, that’s all from me. Keep it salty.

Rusty.

Information about the Agate Beach Surf forecast

The above surf forecast table for Agate Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Agate Beach 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 Agate 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.
