Current pilot readout for KNRS
KNRS is currently VFR with variable winds at 4 knots, visibility 10+ statute miles, and a 25,000 ft ceiling. Density altitude is approximately 800 ft (field elevation 23 ft). KNRS does not publish a TAF. The nearest TAF station is KNZY, about 9 nm away.
KNRS by the numbers
What the long-run records say about flying here, computed for this airport alone.
KNRS reported VFR in 71% of daylight observations over 20 years, about 254 flyable days a year. January is the most reliable month and June the least, with IFR or worse 13% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 7% of hours, visibility under 3 miles 3%).
Over 20 years of hourly winds, the west-facing ends (26, 27) had the best headwind 72% of the time, the east-facing ends (08, 09) 28%, and winds were calm 23% 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 8 days a year. From December to February KNRS was IFR or worse 6% of the time, against 12% from June to August.
Fog was reported on about 23 days a year, and fog or mist on 130. January and December are the foggiest months, with fog in 10% of hours, against 4% in May.

Runway wind check
Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Current wind is variable at 4 kt: light and variable wind like this is generally not a factor for runway selection, and with no steady direction 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.
