Daily mean wind direction and winds speed
in knots, averaged over 24 hours from midnight to midnight. Mean wind directions are given as bearings and as cardinal (compass) directions. The data for mean windspeed is also categorised according to the Beaufort scale ( pic at the bottom)

- This is the highest instantaneous windspeed recorded.
- The direction from which the maximum gust was blowing is also recorded.
- A knot (kn) is a ‘nautical mile per hour’.
- 1 kn = 1.15 mph.
Daily maximum relative humidity
given as a percentage of air saturation with water vapour. Relative humidities above 95% give rise to misty and foggy conditions
Daily mean cloud cover
measured in ‘oktas’ or eighths of the sky covered by cloud
Daily mean visibility
measured in decametres (Dm). This is the greatest horizontal distance at which an object can be seen in daylight
Daily mean pressure
- measured in hectopascals (hPa)
For the overseas/ international locations, the only data recorded are
- Daily mean temperature
- Daily total rainfall
- Daily mean pressure
- Daily mean windspeed
