Runways at KRHV
According to OurAirports data (compiled from AIP and FAA sources), Reid-Hillview Airport of Santa Clara County (San Jose) has 2 runways: 13L/31R - 945 m long (3,100 ft), 23 m wide, asphalt surface; 13R/31L - 945 m long (3,099 ft), 23 m wide, asphalt surface.
The longest of them is 13L/31R, at 945 m.
Runway headings and wind
The thresholds are oriented as follows: 13L/31R on 130° and 310° magnetic, 13R/31L on 130° and 310° 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 13L/31R axis, wind from the south-west (around 220°) or from the north-east (around 40°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 130° or 310° 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 KRHV
Weather reports for Reid-Hillview Airport of Santa Clara County (San Jose) are published under the ICAO code KRHV. 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 KRHV 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 KRHV, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Los_Angeles zone is GMT-08:00 in winter and GMT-07:00 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 Mineta San Jose International Airport (KSJC, 10 km), Moffett Federal Airfield (Mountain View) (KNUQ, 22 km), Palo Alto Airport (KPAO, 30 km). When no report is available for KRHV, they usually give the best approximation of conditions in the area.
