June is usually reliably more rainy than May.
Except this year.

| Bar chart showing combined May and June rainfall from 1990 to present. Despite a bit of a slump in June, May picked up the slack to deliver about 17 inches of rain. That’s above average (i.e. the dotted line), but not as much as last year’s whopping 25 inches. |
Although in this case, don’t blame June.
The second half of May was especially stormy.
In that respect, a better way to look at June rainfall is to lump it together with May’s second half.
That’s the true number the ecosystem sees.
And as for keeping score, there was no upset:
May and June are the same team.
