Alright, Rusty here lookin’ at the surf ahead. The next couple weeks are a bit of a mixed bag with a real standout near the end for those who can wait.

Right now and for the first week and a half, it's a struggle. We're looking at mostly small, weak, and messy surf. The swell combo is weak, barely hitting low triple digits in energy (263). Winds are mainly cross or cross-onshore, chopping things up. The water temp at Seaside Cove is sitting at 14.7°, which is pretty much average for this time of year, nothin' weird there. But the surf is just poor. Friday the 3rd and into the weekend, you’ve got waist-high waves at best, around 1ft to 1.6ft from the WNW, but that 8-second period means it's weak and fat. Cross-winds and chop dominate through the whole first week.

Monday the 6th morning offers a slight glimmer with a 1.6ft WNW swell, period bumping to 10 seconds, and moderate wave energy (490). Still cross-shore winds, though, so it’s marginal. Not worth paddling out for much. That kind of mediocrity stretches all the way through to mid-July. A long, quiet stretch of knee-to-waist high, short-period junk with onshore or cross-shore slop.

Now, here’s the one to circle on your calendar. Wednesday morning, July 15th. That’s the standout. Seaside Cove wakes up to clean, glassy conditions. The wind is almost nothing from the W, dead calm – pure glass. The swell is only 2ft, but it's coming from the west with a very long 21-second period. This is proper groundswell energy, and the combined energy jumps up to 639 – moderate but punchy for the size. That long period means longer waits between sets but much better shaped, more powerful waves. At this size, it’s perfect for beginners and longboards, but the quality will be high. Expect clean, lined-up waves off the point. The afternoon gets a bit onshore, so hit the morning session.

Thursday the 16th also shows some lingering W swell with a 17-second period and solid energy (706), but the wind swings around to a cross-shore NNW breeze, chopping it up a bit. Still worth a look if you missed Wednesday. After that, the swell fades out again into the following weekend with smaller, weaker waves and onshore winds returning.

So, bottom line: the first week and a half is a write-off. Surf is small, weak, and blown out. The one true standout is Wednesday July 15th – glassy, long-period, clean waves at Seaside Cove. That’s your day.

Information about the Seaside Cove Surf forecast

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

Seaside Cove is 24 km (15 miles) from Astoria. If you plan a vacation in North Oregon, look for hotels and other accommodation in Astoria. Astoria has rooms for a wide range of budgets as well as car hire and transport links.
