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.

Features:

	Included is a night-and-day algorithm and daylight savings. 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.
