This chart shows the temperature, dew point and relative humidity.
The chart is interactive, so you can click on any point to see its value.
Weather stations with partial metar schedule will show a discontinuity.
All times are UTC.
QNH and Density Altitude
This chart shows the QNH (in hPa). For those fields with known elevation density altitude (in feet) is also shown. Field elevation: 37
Wind Direction and Intensity
This chart shows the Wind intensity, gusts (both in kt) and directon (deg).
Note that wind intesity is the average speed over a 2-minute period (direction may not be reported when below 6 knot)
Note also that Gusts are indicated by rapid fluctuations in wind speed with a variation of 10 knots or more between peaks and lulls
