Norton Municipal Airport is an airport with the ICAO code KNRN. Country: United States. Nearest settlement listed in the database: Norton. OurAirports classifies it as a small airport. Its ICAO code starts with the KN prefix, which marks airports in United States. No IATA code is assigned, which is typical for airports without scheduled traffic. The airport reference point sits at 39°51'01"N, 99°53'41"W, at an elevation of 2,383 ft (726 m) above sea level. The applicable time zone is America/Chicago.

The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
What the METAR reports from KNRN for 2023-2025 show - counted hour by hour.
We computed these statistics from 23,608 METAR reports issued by KNRN in 2023-2025. VFR conditions prevailed 86% of the time, MVFR 7% and IFR or LIFR 6%. Best month for VFR flying: June (92% of hours VFR). Most IFR and LIFR hours: January (14%).
Through the day, IFR or LIFR conditions are most frequent around 14:00 UTC (12% of reports at that hour) and least frequent around 23:00 UTC (3%).
Fog (FG) was reported on 23 days a year on average, most often in January. Thunderstorms (TS) occurred on 2.1 days a year on average, and snowfall on 24.
The wind most often blows from S (180°) - 11% of reports. Calm (0 kt) made up 8% of reports, and gusts of 25 kt or more appeared in 5%. Warmest month: July (average high 33.3 °C); coldest: January (average low -7.9 °C).
Day counts are for the selected period (for all years - the yearly average).
The top of each bar is the average daily high, the bottom the average daily low (usually around dawn), in °C.
Most often: S - 11% of reports. Each petal shows the direction the wind blows from (as in METAR) - the longer it is, the more often. Colour shows wind speed.

According to OurAirports data (compiled from AIP and FAA sources), Norton Municipal Airport has 2 runways: 08/26 - 645 m long (2,117 ft), 38 m wide, grass surface; 16/34 - 1,433 m long (4,701 ft), 18 m wide, asphalt surface.
The longest of them is 16/34, at 1,433 m.
The airport combines paved and grass surfaces: 1 paved and 1 grass runway each.
The thresholds are oriented as follows: 08/26 on 80° and 260° magnetic, 16/34 on 160° and 340° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 08/26 axis, wind from the south (around 170°) or from the north (around 350°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 80° or 260° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
Weather reports for Norton Municipal Airport are published under the ICAO code KNRN. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the KNRN report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KNRN, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Chicago zone is GMT-06:00 in winter and GMT-05:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Phillipsburg Municipal Airport (KPHG, 51 km), Hill City Municipal Airport (KHLC, 53 km), Oberlin Municipal Airport (KOIN, 55 km). When no report is available for KNRN, they usually give the best approximation of conditions in the area.
