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 LIRS for 2023-2025 show - counted hour by hour.
We computed these statistics from 25,999 METAR reports issued by LIRS in 2023-2025. VFR conditions prevailed 91% of the time, MVFR 8% and IFR or LIFR 1%. Best month for VFR flying: August (97% of hours VFR). Most IFR and LIFR hours: February (2%).
IFR and LIFR conditions are rare here at any time of day.
Fog (FG) was reported on 6.7 days a year on average, most often in February. Thunderstorms (TS) occurred on 30 days a year on average, and snowfall practically never.
The wind most often blows from NNE (23°) - 15% of reports. Calm (0 kt) made up 1% of reports, and gusts of 25 kt or more appeared in 1%. Warmest month: August (average high 32.2 °C); coldest: December (average low 4.9 °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: NNE - 15% 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), Grosseto Corrado Baccarini Air Base / Grosseto Airport (Grosseto (GR)) has 2 runways: 03/21 - 2,994 m long (9,823 ft), 45 m wide, asphalt surface; 03R/21L - 2,354 m long (7,723 ft), 25 m wide, asphalt surface.
The longest of them is 03/21, at 2,994 m.
The thresholds are oriented as follows: 03/21 on 30° and 210° magnetic, 03R/21L on 30° and 210° 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 Grosseto Corrado Baccarini Air Base / Grosseto Airport (Grosseto (GR)) are published under the ICAO code LIRS. 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 LIRS 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 LIRS, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Europe/Rome zone is GMT+01:00 in winter and GMT+02:00 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 Aliscarlino Airfield (Scarlino (GR)) (LIQY, 27 km), Siena-Ampugnano Airport (Ampugnano (SI)) (LIQS, 57 km), Marina di Campo Airport (Campo nell'Elba (LI)) (LIRJ, 68 km). When no report is available for LIRS, they usually give the best approximation of conditions in the area.
