Water temperatures typically hover between 60 and 75 degrees Fahrenheit in most areas, drawing bass toward shallower structures like weed edges, points, and drop-offs where baitfish congregate. Always check local regulations for bag limits and seasons, as some states impose catch-and-release for smallmouth during fall. Focus on finesse presentations in pressured waters and power fishing where bass roam freely.

Let's dive into region-specific strategies, incorporating current weather insights for early September.

Pacific Northwest Bass Fishing in September

In the Pacific Northwest, including Washington and Oregon, September brings milder weather with highs of 65 to 75°F and lows of 45 to 55°F. Expect partly cloudy skies with 2 to 3 inches of precipitation, mostly light rain, oxygenating waters without excessive runoff. Water temperatures around 60 to 65°F push bass into 5 to 15-foot depths, chasing baitfish as cooling trends intensify.

Prime spots include the Columbia River near Vancouver, Washington, where smallmouth congregate on rocky points, and the Willamette River shallows near Portland, Oregon, perfect for largemouth in weed beds. Potholes Reservoir in Washington offers flooded timber in 8 to 12 feet, while farm ponds east of the Cascades target lily pad edges.

Top lures: The Z-Man Finesse TRD in Green Pumpkin, Texas-rigged, thrives in shallow weeds for subtle presentations. In deeper river runs, a Z-Man CrossEyeZ Finesse Craw in Brown on a football jig bounces along rocky bottoms. For covering water, the Strike King KVD 1.5 Squarebill in Natural Shad excels during low-light mornings.

From a bass boat, cruise river channels at dawn, casting jigs parallel to current breaks.

Kayaks: shine in ponds, drifting TRDs near inflows.
