WaterWeb reads data from a weather station located on the roof of the Christchurch City Council Building. Data is updated every minute, 24 hours a day.
The weather condition is calculated using the temperature and rainfall as factors, and the current weather icon displayed may not be an accurate indication due to the absence of a light meter on the weather station.

Sunset and Sunrise is accurate to +/- 2minutes.|
|Windchill is calculated using [outside temperature] - ([wind
speed in km] / 2.85) . |
|Current icon is determined by:|
temp + [(15 - [avg temp for month])/3,
where temp = ([outside temperature] + [wind chill temperature]) / 2
|Rainfall is measured by reporting the total rainfall in the last 30 minutes.|
