KSPF by the numbers

What the long-run records say about flying here, computed for this airport alone.

86%
of daylight hours VFR, 2006 to 2025

KSPF reported VFR in 86% of daylight observations over 20 years, about 287 flyable days a year. August is the most reliable month and February the least, with IFR or worse 10% of the time. When conditions drop it is usually a mix of low ceilings (under 1,000 ft 5% of hours) and low visibility (under 3 miles 5%).

32%
of windy hours favor runway 26

Over 20 years of hourly winds, runway 26 had the best headwind 32% of the time, runway 31 22%, 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.

63
snow days a year

Snow fell on about 63 days a year. From December to February KSPF was IFR or worse 10% of the time, against 2% from June to August.

52
thunderstorm days a year

Thunderstorms were reported on about 52 days a year. 69% of storm hours fall in June, July and August, peaking in July when storms were in the air 3% of the time.

5,967 ft
typical summer-afternoon density altitude

Field elevation is 3,933 ft, but on a median summer afternoon the air performs like 5,967 ft, 2,034 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.

24%
of hours with gusts

Gusts showed up in 24% of hours, typically 7 kt above the steady wind, and the strongest credible gust on record was 67 kt. January is the windiest month (mean 9 kt) and August the calmest.

Sources: hourly observations 2006 to 2025 and the per-runway wind climatology 2006 to 2025. Historical summaries, not a forecast: check the current METAR, TAF and a briefing before flight.

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.
