1 Rain season: Jan 1st to Dec 31st.   4 Updated at 12pm.   5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present).   7 Leaf Wetness is surface moisture on foliage. 0 being totally dry and 15 being totally saturated.   8 Soil moisture and temperatures are from sensors burried in the ground at the levels specified.   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average to day 19 of August- for this station since 2012.   11 Historical average rain this season to day 19 of August- for this station since 2012. 12 The Feels Like temperature is derived from the Temperature, Humidity, Solar and Wind values recorded by the weather station.
