The Lowdown
Alright, grab your board, let's look at what Agate Beach has in store for the next 16 days. This point break is exposed to a westerly swell and is pretty consistent without being a zoo, but the forecast is a real roller coaster.
We're starting off shaky. For the rest of today, Thursday the 10th, we've got a weak 2ft swell from the southwest, and the wind is a messy cross-shore out of the north-northwest at 12 mph. The water is 59°, which is normal for this time of year. The wave energy is moderate (520), but it’s not worth getting wet for.
Then, Friday the 11th morning is our golden ticket. The swell jumps up to a clean 6ft from the northwest, and the wind just dies to a glassy 3 mph out of the north-northwest. The wave energy is strong (761), and the period is a solid 9 seconds. This is a short-lived moment of pure, clean surf. That’s the best session of the whole forecast, hands down.
Friday afternoon, the wind turns onshore and the surface gets ugly, so don't expect it to hold.
After that, we hit a long, sad stretch. From Saturday the 12th all the way through Sunday the 20th of September, it’s just poor to marginal conditions day after day. The swell drops, winds are either cross or onshore, and it’s choppy. There’s a tiny bit of hope on Monday the 15th morning with a 4ft northwest swell, but it’s crossed-up and rough. For over a week, it’s a write-off.
Come the 22nd and 23rd, a real pulse of power shows up. On Tuesday the 22nd, we get a 6ft to 8ft northwest swell, with the energy readings hitting strong levels (645 to 756). The problem is the period is short at 7 seconds, and that cross-wind messes it up. By Wednesday the 23rd morning, the swell holds at 8ft from the northwest with a 9-second period, and the energy is very strong (1083). That’s a proper, powerful swell, but the cross-wind will chop it up. At that size on a bad wind day, it’s for the experts only.
The forecast ends on a good note. Friday the 25th morning gives us a clean 4ft northwest swell, glassy conditions with 3 mph winds from the northwest, and moderate wave energy (411). That’s a solid, clean way to finish.
So, to wrap it up: your one true standout is Friday morning, the 11th of September, for the cleanest, most fun waves with that glassy texture and 6ft northwest swell. The other big moment, but one for the experienced crew, is Wednesday morning, the 23rd of September, when the big swell arrives, though it’ll be fighting the wind.

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. Our Agate 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.

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.
