Plot Description:

This plot displays the accumulated number of days that the high or low temperature was above or below some threshold. This uses somewhat sloppy day-of-year logic that does not necessarily align leap years.

If you split the year on 1 July, the plotted season represents the 1 July year. ie 1 July 2023 - 30 Jun 2024 plots as 2023.
