The Lowdown
Alright, Rusty here. Let’s see what’s cookin’.
Gotta be straight with you – the outlook for Agate Beach over the next 16 days is a grind. There’s swell, but the stars never line up for a clean session. The water is running much colder than normal for this time of year, nearly 4° cooler than average, so you’ll want a thick suit if you’re even thinking about paddling out.
The first real chance of anything surfable kicks off Thursday the 16th of July, but it’s pretty marginal. Early morning we’ve got a tiny 2ft swell from the WNW with a very long 19-second period, and the combined energy is moderate (426). The wind is a light cross-onshore, so it’ll be a bit bumpy. That long period groundswell might offer some shape, but it’s a point break, so it could still work. The afternoon is a write-off with poor conditions.
Friday the 17th and Saturday the 18th see the swell bump up to 3ft, but the wind stays cross-onshore, getting a bit stronger and choppier. The energy climbs to moderate-strong (574-804), but the quality just isn’t there. The swell period drops to 16-17 seconds, so it’s still long-period groundswell, but the wind messes it up.
Sunday the 19th and Monday the 20th bring the biggest swell of the whole period, hitting 6ft from the NW with a short period around 8 seconds. The combined energy is strong (706-749), but the wind is cross-shore to cross-onshore, making it choppy and messy. This is a beach-and-reef setup, so with that short-period, wind-affected swell, it looks more interesting for kite surfing than paddle surfing. These waves are also too big for beginners.
The rest of the first week and into the second week, from the 21st of July through to the 31st, is a real struggle. The swell drops back to 1ft to 5ft, and while the wind is sometimes light, the conditions are almost always rated as marginal or poor. There are no standout days. The best of a bad bunch might be the early morning of Tuesday the 28th, with a 3ft SW swell at 19 seconds, light cross-on wind, and moderate energy (539), but it’s still only a marginal call.
Honestly, there’s no single session I’d drive for. The waves are there, but the quality is missing. It’s a long stretch of nothing special, but with this kind of consistent but messed-up pattern, the forecasts can change, so keep checking back.
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. 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. If you surf the same spot (Agate 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 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.
Agate Beach is 64 km (40 miles) from Corvallis. If you plan a vacation in South Oregon, look for hotels and other accommodation in Corvallis. Corvallis has rooms for a wide range of budgets as well as car hire and transport links.
