I was looking at the highs (like you always do when comparing Chicago to London). This month has been cloudy, which is why the lows are so high.
We aren't comparing two different cities. We are comparing this March with a normal April in London. And I always look at both the Mean as well as the average highs
Ok so the highs currently 13.3C versus a normal April which is 14.2C. Not even 1C difference and judging by your forecast it looks like the average high this March will certainly approach that of a normal April.
.
If the forecast is correct, the month will end up with an average high of 13.7c (+2.4c above 81-10, or +2.0c above the 30 year average), and be cloudier than normal.
January was cold with average sun. February was mild and very cloudy.
Warm nights def help leafing out. You can't deny that.
But warm autumns/early winters delay some species that need to experience sustained cold temps (below 5c) to start leafing. Lack of sunlight can also delay them.
Last spring was delayed due to a mix of warm temps in Nov/Dec, and a cold spring. This year had a warm early winter, then extreme cloudiness since February, which would cancel out the milder temps.
It may be earlier by a few days or so, but it's nothing remotely out of the ordinary. If we were fully leafed out by early or mid April then that would definitely be noticeable, but we won't be. It's mid-late April almost every year (apart from years such as 2006, 2010 or 2013).
Why are you showing us pictures of London from a year ago?
If you really want to impress everyone with the glory of London's climate there are about 20 London vs Whichever threads you can dig up. Most relevant to the topic at hand though is this one:

I doubt that extreme cloudiness cancels out above avg temps. Plants and trees respond far more quickly to warmer than avg air than sunshine imo. Cloudy warm Feb and March would result in earlier April leafing.
I still think you are ahead of leafing because of such warm March temps and a warm Feb. Feb and March are the key months for April leafing imo. I've seen it here last year. And this year was the same until the cold came. If all of a sudden your weather turned consistently below average from here to the end of April your leafing would dramatically slow down I would bet. Temps matter more than sunlight.
I wasn't referring specifically to growing degree days but instead to the fact that no matter what London is like in March it still has rather cool summers. Even Southern Ontario has far more summery summers.
I'd much rather live in London's climate than anywhere in Ontario (or Chicago for that matter). The only place in Canada with a decent climate is the Vancouver area.
So sick of seeing this now. Day #14 in a row with snow around.
March 23, 2017
