The northern Oregon coast is currently experiencing stable marine weather conditions today as a weak low-pressure system lingering offshore continues to dissipate. High atmospheric pressure dominates the outer waters to maintain a reliable, cool onshore flow along local beaches and outer reefs. Across popular areas like Astoria, Seaside, and Cannon Beach, skies remain mostly clear to partly cloudy with afternoon temperatures peaking in the mid-60s (°F), while light northwesterly winds persist between 5 to 10 knots before occasionally increasing to 15 knots late this evening.
Ocean conditions remain manageable for regional watercraft with combined seas averaging a steady 3 to 5 feet across most coastal zones. Data from nearby offshore buoys shows the dominant energy arriving as a primary west-northwest swell measuring 4 feet at an 8-second interval, providing uniform lines across the reefs. This is paired with a faint, longer-period secondary southwest groundswell arriving at 2 feet with a 14-second period, resulting in overall average wave sizes running in the waist-to-chest-high zone along exposed beach breaks.
Tidal distributions along the northern coast are tracking cleanly through the day to provide distinct shifts in water depth for beachgoers and coastal mariners. A deep low tide bottomed out earlier this morning at approximately 6:35 AM reaching a low of -1.6 feet, which exposed extensive intertidal zones. The water level then crested at a high tide of 6.2 feet at 1:19 PM, and it is now steadily receding toward a mild secondary low tide of 3.0 feet scheduled later this evening at 6:12 PM.
Tomorrow's outlook promises a continuation of this stable mid-summer pattern as the offshore ridge of high pressure reinforces the regional pattern. Clear morning skies will give way to a few scattered afternoon clouds while northwest winds climb back up to 10 to 15 knots. Marine conditions will remain highly consistent with total combined seas holding steady between 3 to 4 feet, driven by a localized 4-foot northwest swell hitting at a clean 7-second period, making for another day of predictable weather and manageable ocean conditions.
