A few notes:
The final summary for yesterday can be seen here.
This page shows the output of a python script that extracts data from a database of observations and derived quantities held at 5-minute intervals.
Averages, totals and extreme values (maxima and minima) are calculated using data at 5-minute intervals, provided that no more than 5 such values are missing.
Consequently the extreme values may differ slightly to those shown on our weather data statistics page where extreme values of observed quantities at 1 second intervals can be seen.

Wind direction is the direction from which the wind is blowing. Here are the conversions to the main 16 compass points: NNE 22.5 deg; NE 45 deg; ENE 67.5 deg; E 90 deg; ESE 112.5 deg; SE 135 deg; SSE 157.5 deg; S 180 deg; SSW 202.5 deg; SW 225 deg; WSW 247.5 deg; W 270 deg; WNW 292.5 deg; NW 315 deg; NNW 337.5 deg; N either 0 or 360 deg.

Many other quanitities are both observed and derived from the measurements - see the system overview and the data acquisation documentation.
Plots of the data can be found on our weather data pages.
