Full moon tides push fall traffic to Buoy 10, Garibaldi
NOAA's Oregon Coast tide stations show a full-moon push building today: station 9435380 read 56.8°F with the next high tide at 1:22 p.m. local, while station 9439040 came in warmer at 64.2°F ahead of a 2:20 p.m. high. That spread is typical of late-September stratification between open coast and estuary water. On the water, IFish.net Fishing Reports carries word of steady trolling traffic through the Buoy 10 area near the mouth of the Columbia, with boats also working Nehalem, Garibaldi, and the mouth of the Lewis — a sign there's plenty of gear in the water even on a week light on formal shop reports.

With a full moon overhead, expect larger tidal swings and stronger current through the week, which typically favors drift and troll presentations that depend on moving water. The two-station temperature gap is worth watching: if the warmer reading near the Columbia mouth holds or climbs, it usually means slower cooling into fall and more fishable days before water turns properly cold. Midday high tides around 1:00 to 2:30 p.m. this stretch make late morning through early afternoon the practical window to fish the turn and the start of the ebb, when current concentrates bait along structure. Expect that high-tide window to slide roughly 45 to 60 minutes later each day, so plan around the moving tide rather than a fixed clock time. The boat traffic reported near Buoy 10 and the Nehalem-Garibaldi stretch suggests conditions are holding well enough to keep bringing gear out through the weekend.
Context
Late September on the Oregon Coast sits at the heart of the fall transition, when nearshore water temperatures typically begin easing down from summer highs while tidal estuaries and river mouths hold heat a little longer than the open coast, which tracks with today's spread between stations. A full moon this time of year is a normal driver of bigger tidal swings and stronger exchange through bays and river mouths. Typically, that keeps boat traffic elevated around the estuaries and river-mouth zones into October before conditions shift toward a more settled winter pattern.
