Official National Weather Service forecasts indicate sunny skies and highs in the low to mid-60s for Seattle on October 12 under dry northeasterly flow aloft from an upper-level ridge, following the recent passage of a cool trough. This setup promotes clear conditions and strong daytime heating, with light winds limiting marine moderation from Puget Sound. Trader consensus clustering around 60–63°F reflects model agreement on these factors, while the narrow split between 60–61°F and 62–63°F bins stems from minor uncertainties in peak insolation, boundary-layer mixing, and exact wind speeds at the official measurement site. Historical October averages near 60°F provide context, though current ridging supports a mild deviation. No significant forecast shifts are anticipated before resolution.
