Plot Description:

This chart presents the longest daily streaks of having some threshold meet. This tool presents a number of variables that may not be observed by your station or network. If you pick a below threshold, then the year is split on 1 July and the year plotted is the year of the second half of that period. Daily Data Request Form provides the raw values for the automated stations. The download portal for the long term climate sites is here.
