other reason for starting earlier-kids are bored by mid August...send them back and let them out earlier as "summer itis" kicks in around Memorial day....
you could have the same issues in June with a later start....rob Peter to pay Paul. The real issue is too many needless snow days...we had 2 to 3 days off last year for wet roads...Christ.
15-16 at least had a fair amount of storminess even if mostly rainstorms...01-02 was warm and dry the entire time outside of a cold 10 days in Late January.
The problem with a strong El Nino is that it's often hyped to be this big deal and it verifies warm and generally snowless outside of a couple of cold weeks usually centered around 2/1 give or take. We lucked out on the coast with the blizzard (got fringed here so to speak as we got 14 inches while places just 40 miles south got 30+) Outside of that storm it was basically a 3 week winter with snow chances ending around President's day (big cold snap ending with an inch of snow to a driving rainstorm)
Rained here most of June. Really sucked. July was cool and dry like you said and August had 4 weeks of humid/warm, it's like the opposite of a warm winter where you get 2-3 weeks of cold and that's it...guess it's the summer version of that.
solid cloud deck here and temps going nowhere...the gloom does remind me a bit of late Sept or Oct where the sun angle is not enough to burn off the stratus...
whoopdee do- a day of 90 in September....it's over as far as the big long lasting heatwave by about 9/1 or so....clock's ticking...days are shortening...soon we'll be singing Xmas tunes...
