Ever woken up on the fourth day of a heat wave and wondered whether this is actually normal? Wonder no more.
This tool compares current and recent conditions where you are to the historical average for that same time of year, so you can see at a glance just how hot, cold, wet, or dry things really are.
Averages are calculated from 1950 onward, the full span of reliable, high-resolution historical data this app's source provides for a specific location. It's worth remembering that humans have been shaping the climate for far longer than that, so even this is not a neutral baseline.
This tool counts how many days this year have crossed a line you choose: over 90°F, under freezing, more than half an inch of rain in a day, whatever you're curious about.
It then compares that count to the historical average (1950 onward) number of days that crossed the same line by this point in the year, so you can see whether this year's extremes are actually unusual, or just an ordinary year doing ordinary things.
Change the number any time. It recalculates instantly, since all of the historical daily data are already loaded and nothing needs to be fetched again.
