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 KBLM for 2023-2025 show - counted hour by hour.
We computed these statistics from 24,753 METAR reports issued by KBLM in 2023-2025. VFR conditions prevailed 79% of the time, MVFR 9% and IFR or LIFR 12%. Best month for VFR flying: November (88% of hours VFR). Most IFR and LIFR hours: April (17%).
Through the day, IFR or LIFR conditions are most frequent around 12:00 UTC (16% of reports at that hour) and least frequent around 20:00 UTC (9%).
Fog (FG) was reported on 23 days a year on average, most often in December. Thunderstorms (TS) occurred on 14 days a year on average, and snowfall on 12.
The wind most often blows from W (270°) - 14% of reports. Calm (0 kt) made up 8% of reports, and gusts of 25 kt or more appeared in 3%. Warmest month: July (average high 30.2 °C); coldest: January (average low -1.2 °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 - 14% 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), Monmouth Executive Airport (Belmar/Farmingdale) has 2 runways: 03/21 - 1,069 m long (3,508 ft), 15 m wide, asphalt surface; 14/32 - 2,239 m long (7,345 ft), 26 m wide, asphalt surface.
The longest of them is 14/32, at 2,239 m.
The thresholds are oriented as follows: 03/21 on 30° and 210° magnetic, 14/32 on 140° and 320° 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 03/21 axis, wind from the south-east (around 120°) or from the north-west (around 300°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 30° or 210° 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 Monmouth Executive Airport (Belmar/Farmingdale) are published under the ICAO code KBLM. 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 KBLM 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 KBLM, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/New_York 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 Lakehurst Maxfield Field Airport (KNEL, 26 km), Ocean County Airport (Toms River) (KMJX, 32 km), Mc Guire Air Force Base (Wrightstown) (KWRI, 44 km). When no report is available for KBLM, they usually give the best approximation of conditions in the area.
