Climate at Winona Municipal Airport Max Conrad Field - statistics from METAR reports
What the METAR reports from KONA for 2023-2025 show - counted hour by hour.
We computed these statistics from 25,792 METAR reports issued by KONA in 2023-2025. VFR conditions prevailed 77% of the time, MVFR 17% and IFR or LIFR 6%. Best month for VFR flying: May (89% of hours VFR). Most IFR and LIFR hours: January (14%).
Through the day, IFR or LIFR conditions are most frequent around 12:00 UTC (12% of reports at that hour) and least frequent around 20:00 UTC (3%).
Fog (FG) was reported on 22 days a year on average, most often in September. Thunderstorms (TS) occurred on 1.4 days a year on average, and snowfall on 35.
The wind most often blows from NW (315°) - 10% of reports. Calm (0 kt) made up 31% of reports, and gusts of 25 kt or more appeared in 1%. Warmest month: July (average high 28.1 °C); coldest: January (average low -8.6 °C).

Runway headings and wind
The thresholds are oriented as follows: 12/30 on 120° and 300° 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 12/30 axis, wind from the south-west (around 210°) or from the north-east (around 30°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 120° or 300° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
METAR and TAF for KONA
Weather reports for Winona Municipal Airport Max Conrad Field are published under the ICAO code KONA. 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 KONA 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 KONA, 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 La Crosse Regional Airport (KLSE, 42 km), Houston County Airport (Caledonia) (KCHU, 56 km), Fillmore County Airport (Preston) (KFKA, 58 km). When no report is available for KONA, they usually give the best approximation of conditions in the area.
