Table - best surf conditions forecast for Seaside Cove over the next 16 days.
Right folks, Rusty here. Gotta be straight with you—this 16-day window at Seaside Cove is a tough one to call. The pattern is pretty grim, with a whole lot of "poor surf" and "marginal" days stacked up. There’s no real standout to hang your hat on, but we’ll pick through the rubble for the best of a bad bunch.
The first hint of anything worth a look doesn’t come until Wednesday the 15th of July. The swell is a modest 3ft from the WNW, with a period of 10 seconds, and the combined energy is moderate at 331. The wind is light cross-on from the NW, which will keep things a bit messy. It’s not good, but it’s the first day that’s not a total write-off. The water is a frigid 54°, a massive 5° colder than average for this time of year, so you’ll need a thick wetsuit and a good attitude.
Thursday the 16th of July morning sees a similar story—4ft swell from the WNW, 8-second period, and the energy ramps up to 454. The wind is a cross-on from the SW, making it choppy. Still, this is the best of the first week, though it’s a long way from clean.
Friday the 17th of July is the first day to scrape a 1 out of 10. The morning has a 2ft swell from the west with a very long 17-second period, and the energy is strong at 634. That long period groundswell could make for drawn-out lines if it finds the right bank, but the cross-on breeze from the SW won’t do it any favours. It’s a gamble.
The real window of opportunity comes on Wednesday the 22nd of July. The morning sees a 6ft swell from the WNW, with a 10-second period and strong energy of 604. The wind is light cross-on from the NW, so it’s not perfect, but it’s the biggest, most consistent-looking day in the whole run. The afternoon is similar at 6ft with a 9-second period. For a beach-reef-and-point set-up like Seaside Cove, this is the pick of the 16 days. The swell is pushing into the intermediate zone—not huge, but a bit too much for beginners. The direction is a solid WNW, which matches the optimum swell direction. It’s not a classic, but if you’re desperate, this is the day to be out.
From Thursday the 23rd of July onwards, it’s a slow fade back into the mediocre. There’s no real standout after that Wednesday. The weekend of the 26th and 27th of July is a write-off of small, choppy, cross-shore slop. The whole 16-day period is a bit of a flat, frustrating stretch of surf. The only day that even comes close to being a highlight is Wednesday the 22nd of July morning, and even then, you’re making do with less-than-ideal wind.
Rusty.

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.
