1 Rain season: Jan 1st to Dec 31st.   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).   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 only to day 25 of just the month of May for this station since 2009.   11 Historical average rain this season to day 25 of May for this station since 2009.   12 Temperature measurements taken a foot below the surface under my dock in Flowers Cove. Temperatures taken when the cove is ice free - usually from mid-April to mid-November. Records started May 17, 2009.
