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 KHTL for 2023-2025 show - counted hour by hour.
We computed these statistics from 21,208 METAR reports issued by KHTL in 2023-2025. VFR conditions prevailed 70% of the time, MVFR 17% and IFR or LIFR 14%. Best month for VFR flying: July (83% of hours VFR). Most IFR and LIFR hours: December (37%).
Through the day, IFR or LIFR conditions are most frequent around 10:00 UTC (20% of reports at that hour) and least frequent around 22:00 UTC (8%).
Fog (FG) was reported on 45 days a year on average, most often in September. Thunderstorms (TS) occurred on 12 days a year on average, and snowfall on 83.
The wind most often blows from W (270°) - 11% of reports. Calm (0 kt) made up 12% of reports, and gusts of 25 kt or more appeared in 4%. Warmest month: July (average high 27.2 °C); coldest: February (average low -7.8 °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: W - 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), Roscommon County - Blodgett Memorial Airport (Houghton Lake) has 2 runways: 09/27 - 1,219 m long (4,000 ft), 23 m wide, asphalt surface; 18/36 - 671 m long (2,200 ft), 30 m wide, grass surface.
The longest of them is 09/27, at 1,219 m.
The airport combines paved and grass surfaces: 1 paved and 1 grass runway each.
The thresholds are oriented as follows: 09/27 on 90° and 270° magnetic, 18/36 on 180° and 360° 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 09/27 axis, wind from the south (around 180°) or from the north (around 360°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 90° or 270° 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 Roscommon County - Blodgett Memorial Airport (Houghton Lake) are published under the ICAO code KHTL. 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 KHTL 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 KHTL, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Detroit zone is GMT-05:00 in winter and GMT-04:00 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 Grayling Army Air Field (KGOV, 36 km), Gladwin Zettel Memorial Airport (KGDW, 46 km), Wexford County Airport (Cadillac) (KCAD, 60 km). When no report is available for KHTL, they usually give the best approximation of conditions in the area.
