What Fall And Spring Weather In Banks Oregon Means

Banks sits at the north end of the Tualatin Valley, right where the Coast Range begins. That location adds a touch more rain and cooler nights than downtown Portland, with frequent morning fog.

• Fall (September–November)

  • September: often warm and drier. Highs in the upper 60s to mid-70s, cool nights in the 40s–50s.
  • October: noticeably cooler and wetter. Highs in the upper 50s to low 60s; lows in the mid-40s. Fall color peaks mid to late October.
  • November: wet and breezy at times. Highs around 48–55°F; lows near 38–44°F. First frosts are possible late Oct–Nov.
  • Rain picks up through the season; expect steady showers, occasional downpours, and sun breaks. Valley fog is common in the mornings.

• Spring (March–May)

  • March: cool and showery. Highs in the low–mid 50s; lows near 38–42°F. Plenty of showers with quick clearing.
  • April: milder, still mixed. Highs around 58–62°F; lows near 40–44°F. More sun breaks, but keep the raincoat.
  • May: the driest spring month. Highs in the mid-60s (70s on nice days); lows in the mid–upper 40s. Wildflowers and longer evenings return.
  • Pollen season ramps up: trees in March–April, grasses in May.

• Snow and wind

  • In town, snow is rare but possible (light dustings). It’s more likely in the nearby Coast Range.
  • Autumn and spring storms can bring gusty wind and tree debris. Power flickers do happen during stronger systems.
