Field notes
The grey is the headline cost — November through May runs persistently overcast with frequent light rain (5+ mm/day in winter). The flip side is July–August, which are arguably the best summer weather in the US: dry, 24°C, long northern-latitude days. Snow in the city is rare; nearby Cascades get plenty.
