The Lowdown

Alright, Rusty here. Let’s talk about the next 16 days for Seaside Cove. It’s looking real quiet, and there’s a big dry spell right at the start. The first few days are an absolute washout, with barely any wave energy and messy wind. There’s a tiny window of something rideable later, but it’s nothing to get excited about.

Right off the bat, Wednesday the 22nd and Thursday the 23rd are a total loss. Swell is tiny, bumpy, and cross-onshore – not worth paddling out. The energy is weak, around 255 (combined energy of all swells directed here), and the wind is ruining any chance of shape. Same story rolls into Friday the 24th where the swell drops to 1ft from the SW, but the period is a long 26 seconds. That kind of groundswell is tricky here, and with a direct onshore wind, it’s just messy.

The weekend isn’t any kinder. Saturday the 25th and Sunday the 26th see a bit more energy, with combined swell energy climbing into the 700s (716 and 734), but the wind is howling from the south at 15-16 mph, cross-shore and choppy. The swell is a weak 3ft to 3ft at 19-21 seconds from the SW, which is long period, but with that wind, it’s a battle. The water temp is about average for the time of year, nothing to write home about.

Then we hit a grey zone. From Monday the 27th all the way through to the end of the first week and into the second week – the 28th, 29th, 30th, 31st, and into August – the surf is just poor. There’s a tiny pulse of energy on the 27th (539) and 28th (521), but it’s all cross-onshore or onshore, and the waves are barely 2ft to 3ft. The wind is light, sometimes clear, but the swell is short-period or doesn’t have any push. The combined energy stays in the 100s to 300s, which is weak.

The only time you might see something slightly better is Monday the 3rd of August. There’s a small bump in swell to 3ft from the W, with a period of 9 seconds, and the combined energy hits 312 in the morning and 349 in the afternoon. The wind is cross-shore from the N and NNW at 12-13 mph, so it’s not clean, but it’s the best of a bad bunch. Still, it’s only a marginal option. The conditions are poor, and the wind is still making a mess of it. It’s a beach, reef, and point setup, so the long-period stuff is hit or miss, but this short-period W swell is just a jumbled mess.

Honestly, this is a tough stretch. The break is consistent, but the swell is just not cooperating. If you’re desperate, the mornings on the 4th and 5th of August have small 2ft W swell with light cross-onshore winds and combined energy in the 400s, but it’s still marginal. Don’t expect much.

Stay patient, folks. The forecast can change, but right now, it’s a long wait for anything decent.

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.
