Morning Tide Swing Frames Early Fall Window on Puget Sound

What's next

Expect water temps to keep easing through the week as nights lengthen and the Last Quarter moon settles in, a combination that typically slows the midday tempo and sharpens activity around the tide changes themselves. This morning's early high-to-low swing favors a dawn start, with the outgoing water through mid-morning the window to fish before things go slack. Heading toward the weekend, that morning tide window will shift later each day, so anyone planning a Saturday or Sunday trip should recheck the predicted highs before heading out rather than assume today's timing holds.

With the swing this tight, a short dawn session timed to the ebb is the higher-percentage play than a long midday outing this week.

Context

Early October sits squarely in Puget Sound's fall transition, when surface temperatures slide out of summer's upper 50s toward the low 50s and, by late fall, into the high 40s. A 51.3°F reading tracks that typical glide path rather than running early or late for the calendar. It's also the season when Washington Sea Grant's SoundToxins program, marking its 20th year monitoring harmful phytoplankton blooms, stays active, a good reminder for anglers who also harvest shellfish to check current biotoxin advisories before keeping a catch.
