Australia's second coldest Feb since 1976

Australia recorded its second coldest Feb since 1976.

All Australian capitals, bar Perth, recorded lower than average temperatures, especially maximum temperatures.

If fact, just doing a bit of playing around on the ABOM website, we come across some interesting information.

Maximum temperatures in Feb have not significantly increased (t = 1.3, p = 0.2). However minimum temperatures in Feb have significantly increased and the graph shows this quite clearly ( = 4.1, p < 0.001).

Maximum temperatures in Jan have not significantly increase either (t = 1.8, p = 0.075), however minimum temperatures in Jan have increased hugely (t = 3.8, p < 0.001).

For December, maximum temperatures have not significantly increased, and make sure you check out the graph because its obvious there is no trend (t = 0.8, p = 0.4). However minimum temperatures in Dec have shown a constant increase in December and the increase is significant (t = 3.8, p < 0.001).

So all throughout summer in Australia, we are not heating up during the day. You can even check out the min and max increases in summer from the ABOM website.

Strange thing this global warming. Has no effect on summer time day temperatures.

I made a post today at climate audit about the urban irrigation effect, which would seem to swamp all other affects on temperatures (pun intended).

I'd say it has dominated urban temps in Oz.

When do most people run their sprinklers?

Feb might be mild but March is a shocker in Adelaide. Record heatwave, 10 days in a row above 35C so far & the next 7 days are forecast between 38 and 40C.

Maybe as it's been really cold in the northern hemisphere it has to be really hot in the south somewhere. Or perhaps the globe tilted a bit more than usual this season. ;-)

yep agree Chris M, it's going to be hard for Australia to be cold this month. Melbourne and Adelaide have been ultra hot. And I presume that tassie will follow suit.

The northern hemisphere has been cold, so it might not be a world wide cold month, only time will tell, but australia is almost bound to have a hot march
