This graph shows how often the selected threshold has been exceeded per year. For consistency,
this chart excludes any years that are missing more than five daily temperature reports or more
than one precipitation report in a single month. Data from
Global Historical Climatology Network, served by
ACIS.
Pan or zoom on these graphs to view other years. Place your cursor on either axis and then scroll, click-and-drag, or hold down your SHIFT key and
