Oregon Coast tides swing hard under this week's Full Moon

What's next

Expect the temperature gap between the two stations to hold or widen slightly over the next few days as the full moon's spring tides push more volume through on each cycle. The two hours bracketing each high and low, especially the midday exchange at both gauges, are the windows worth planning around this weekend, since moving water this pronounced tends to concentrate activity near current seams and structure.

As the moon wanes past full over the coming days, tidal ranges should ease into a calmer stretch by early next week. Check the latest marine forecast before an ocean launch, since wind running against an outgoing spring tide can build a rough bar quickly.

Context

Late September sits at the heart of the Oregon Coast's fall transition, when ocean temperatures begin sliding from summer highs and coastal systems start carrying more freshwater as seasonal rains approach. A gap of roughly 6°F between the two readings above is typical for this stretch of the calendar rather than anything unusual. Full Moon spring tides are also on schedule for the season, not an early or late signal, just the normal lunar cycle layering onto the fall shift already underway.
