All Average Temps recalculated for 24hrs instead of Max+Min/2.
Individual Data changed to reflect extremes from LCD and NCDC Data.
All Average Sky Cover changed to reflect data from 00Z through 00Z daily.
All Sky Cover changed to Octas.

Peak wind speed, peak wind direction, precipitation, sunshine amount, and present wx reported in NZST.
Insufficient data to convert these values to UTC.

All temperature, wind, and pressure data taken from NCDC data. LCD data originally reported in NZST.
