KISW by the numbers
What the long-run records say about flying here, computed for this airport alone.
KISW reported VFR in 76% of daylight observations over 20 years, about 245 flyable days a year. July is the most reliable month and December the least, with IFR or worse 21% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 7% of hours) and low visibility (under 3 miles 5%).
Over 20 years of hourly winds, the south-facing ends (18, 20) had the best headwind 30% of the time, runway 30 29%, and winds were calm 18% of hours. Winds most often blow from the west. Crosswind on the best available runway topped 15 kt in under 1% of hours.
Snow fell on about 57 days a year and freezing rain or drizzle on 6. From December to February KISW was IFR or worse 16% of the time, against 7% from June to August.
Fog was reported on about 44 days a year, and fog or mist on 174. January and December are the foggiest months, with fog in 17% of hours, against 6% in July.
Gusts showed up in 16% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 60 kt. April is the windiest month (mean 8 kt) and August the calmest.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is calm: calm wind is not a factor for runway selection, and with no wind there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
