Coastal weather conditions across Southern Oregon feature patchy morning dense fog transitioning to breezy afternoon skies. Air temperatures range from expected highs around 69°F near Coos Bay down to nighttime lows near 53°F around Chetco Cove. A Small Craft Advisory is currently active along the coastal waters from Florence down to Point St. George, where north winds are building from 15 to 20 knots up to 25 to 30 knots in the afternoon, producing steep wind-driven seas across the region.
Ocean swell patterns are dominated by primary northwest waves averaging 4 to 8 feet in size with a short period of 7 seconds, along with a secondary light southwest swell running around 2 feet at a longer period of 15 to 16 seconds. Regional buoy observations show average overall wave heights holding steady between 3 and 5 feet in offshore zones, though nearshore waters south of Cape Blanco are experiencing building seas reaching 5 to 8 feet under localized gusty northerly wind pressures.
Tidal activity across Southern Oregon harbors includes a morning low tide of roughly 0.5 feet at 3:57 AM PDT followed by a high tide near 5.1 feet at 11:02 AM PDT. The secondary afternoon low tide dips to 3.7 feet around 3:36 PM PDT before reaching the primary evening high tide of 6.7 feet at 9:31 PM PDT.
Tomorrow's outlook indicates winds shifting around to the south-southeast at 5 to 15 knots as the main belt of stronger winds pushes farther into the outer waters. Combined seas will subside back down to 3 to 5 feet on Monday afternoon, bringing generally calmer ocean conditions and light variable winds heading into Tuesday.
