How does the historical average go up while the current is well below the average? That doesn't make sense. What am I missing?

If I understand it correctly, the "average" line gives the average for this day of the year, so it moves up and down periodically. But I'm not sure and it's not explained, what the "historical average" actually is, especially how long that "history" is...

are you asking why the average since theyve begun measuring and keeping the values doesnt go up and down at the same rate as the instantaneous level? you do know what an average is right. especially the last year when they had a serious drought and it just kept going down while the average is usually much higher.

No that's not what I'm asking at all you snarky ass. The other answer is probably the correct one, that being the average for that day historically.

I was assuming a cumulative average or even a moving average was being used and if that were the case then there should not be a scenario where adding a current measurement that is lower than the average would actually raise the average. If I need to point you to the actually moment where this happens, I will be happy to.
