Weather Station
<Details>About Temperature

Temperature and Humidity readings are obtained from a Davis Weather station.

Readings are both Celsius (°C) and Fahrenheit (°F). The trend arrows show temperature increase (↑), decrease (↓) and no change (→). On warm or cool days 'heat index' or 'wind chill' is shown.
High/Low Today readings are since midnight.
Last 31 Days indicates season temperature trends. Heating Degree Days (HDD) in the winter and Cooling Degree Days (CDD) during the summer are a measure of energy used to heat or cool a home.
Dew Point is a measure to predict dew, frost and fog. In late afternoon it can help to predict the overnight low temperature.
Humidity simply refers to the water vapour in the air.
Records are since August of 2011Month this Weather station came on line, and updated every few hours.
