Weather Summary for the Current Month

The information shown below comes from my Davis Vantage Pro weather system. I use the temperature and wind speed data in my "official" reports. I have found that the Vantage Pro rainfall amounts are often inaccurate. I use the measurements from an 8" NWS rain gage for all my final reports.

Heating and cooling degree days are calculated using the integration method and a base temperature of 65°F. This is more accurate than the high / low method. It can result in both heating and cooling degree days being recorded on the same day.

The daily mean temperature is calculated by adding the hourly temperature readings divided by the number of hours.
