Is it just me, or is it downright scary that early summer is once again seeing a string of plus 30 degree days? What comes after 32 degrees? (Not to worry, though – as Matt Drudge is so determined to remind us on a weekly basis, somewhere in North America it’s chilly, so don’t you worry your pretty little head.). Update: Oh – never mind.

Come to PEI, where you are free to freeze your ass off for another 2 weeks at least! ;)
My bags are packed and at the door. (!)

Jeez, I guess Drudge might be on to something. Let’s try 32 degrees:
[('1988-06', 5),
('1956-06', 4),
('1994-06', 3),
('2003-06', 3),
('2005-06', 3),

('1998-06', 1),
('1999-06', 1),
('2001-06', 1),
('2006-06', 1)]
33 or over:
[('1988-06', 3),
('2005-06', 3),
('1956-06', 2),
('1991-06', 2),
('1995-06', 2),

If you see a pattern, please let us know. Data & program available if you want it.
And by decade:
30 :
[('2000-06', 32),
('1960-06', 29),
('1950-06', 25),
('1980-06', 24),
('1990-06', 23),
('1970-06', 12)]
Definitely more 30 days in the 2000s, especially since we have 2.5 more Junes to go.
32 :
[('1980-06', 9),
('1990-06', 9),
('1950-06', 8),
('1960-06', 8),
('2000-06', 8),
('1970-06', 3)]
But when we look at very hot, the trend is not so obvious (though it’s likely it will be the highest still).
Also note the super-cold ’70s.
Well, I haven’t looked very closely, but in general it certainly seems that over time there have been more warm days. The data from your previous post suggests that 16 of the 24 Junes since 1954 in which there have been plus 32 days have been in the last 20 years vs the first 30. For 33 degrees, that’s 8 out of 12.
I’ll put a disclaimer in here about any “seat of the pants” statistical analysis, such as you and I are doing here. This stuff tends to be tricky…
That said, you’ll note that where the 1970s gets situated in one’s calculations makes a large difference, since it was really cold. And one should ask one’s self: “what would I be saying if I was only looking to the data up to 1979?”, which further reenforces my initial point.
Also want to note that the first 3 years of the 1950s aren’t in the data set either!
However, I think looking at the data above it’s fairly clear that this June would not stand out of place in any decade previous except the 1970′s, and I’m fairly certain that May was unusually cool (though I haven’t downloaded the data and run the analysis.
