Yes, this is very unusual for May.

"Cold blast has country shivering May 13, 2011 - 4:24PM The recent blast of cold air is having a wide-reaching effect, with unseasonable cold from Tasmania to the northern tropics. It has been at least 30 years since a series of cold fronts has had such an impact this early in the year, affecting almost every state and territory, Brett Dutschke, senior meteorologist at weatherzone.co.au said. It's been more than 50 years since Sydney, Canberra and even Mount Isa have been as cold this early in the year." www.smh.com.au/environment/weather/cold-blast-has-country-shivering-20110513-1elx6.html

" South-eastern Australia wakes to a deep freeze Steve Jacobs May 16, 2011 - 3:24PM The temperatures of Sydney's western suburbs fell below freezing today as the run of extremely cold mornings continued across much of south-eastern Australia. The past two mornings in Sydney (measured at Observatory Hill) have fallen to just 7 degrees, the coldest conditions since last winter, Alex Zadnik, meteorology team leader at weatherzone.com.au said. The average minimum temperature so far this month in Sydney is running at 10.5 degrees, 1 degree below the May average.

Official NIWA New Zealand temps for May 2.3deg C warmer, the highest since records began and i think they are right i have Daffodils flowering and Roses still flowering and still collecting Tomatoes from my hot house.The amazing thing was that on the interview on the national news they never once mentioned global warming, just explaining that it was a normal La Nina they may be learning at long last,but then i suspect that the warm May was just hot air from Hansen being in the country.

Darwin, Sydney and Melbourne have just "enjoyed" the coldest May for decades. In the case of Darwin, all-time record I think.

NZ is lucky that Al Gore didn't show up...........they could have set new records!

More "Coldest May on record for Darwin Ellen Wescott-Dawson May 31, 2011 Darwin and other parts of Northern Australia have just had their coldest May on record. According to weatherzone.com.au, Darwin's average temperatures were more than two degrees colder than average by night and more than a degree colder than average by day, with overnight minimum's averaging 19.9 degrees, and daytime maximums just under 31 degrees." www.theage.com.au/national/coldest-may-on-record-for-darwin-20110531-1fe1x.html#ixzz1NvpOtwzC

I think a record cold month for Darwin is a bit of an oxymoron, from my experience of living at those latitudes it goes from stinking hot in the wet to glorious in the dry. Maybe less hot than normal would be better. I'm in SE Queensland now and have been for the last eight years, definitely some changes going on, nothing to do with Coca Cola bubbles me thinks.

I'm in SE Queensland too, have been for sixty-five years. What changes do you see ShmoHawk?

The wet weather would be the most obvious change, I'm talking about weather here btw, I don't think the local climate is going to flip to a antipodean tundra just yet. For me It's a bit like we're getting Coffs Harbours weather on the Gold Coast if you know what I mean.

An interesting article on Antarctica was recently published in Nature Geoscience; "Winter warming in West Antarctica caused by central tropical Pacific warming" www.nature.com/ngeo/journal/v4/n6/full/ngeo1129.htmlThe authors describe a mechanism to explain the recent observed warming in the Antarctic Peninsula and most importantly, West Antarctica, "The Pacific sector of Antarctica, including both the Antarctic Peninsula and continental West Antarctica, has experienced substantial warming in the past 30 years. An increase in the circumpolar westerlies, owing in part to the decline in stratospheric ozone concentrations since the late 1970s, may account for warming trends in the peninsula region in austral summer and autumn. The more widespread warming in continental West Antarctica (Ellsworth Land and Marie Byrd Land) occurs primarily in austral winter and spring, and remains unexplained. Here we use observations of Antarctic surface temperature and global sea surface temperature, and atmospheric circulation data to show that recent warming in continental West Antarctica is linked to sea surface temperature changes in the tropical Pacific. Over the past 30 years, anomalous sea surface temperatures in the central tropical Pacific have generated an atmospheric Rossby wave response that influences atmospheric circulation over the Amundsen Sea, causing increased advection of warm air to the Antarctic continent. General circulation model experiments show that the central tropical Pacific is a critical region for producing the observed high latitude response. We conclude that, by affecting the atmospheric circulation at high southern latitudes, increasing tropical sea surface temperatures may account for West Antarctic warming through most of the twentieth century.

For me It's a bit like we're getting Coffs Harbours weather on the Gold Coast if you know what I mean. We might if you included your location in your profile ..... FWIW, Australia has just had its coolest Autumn (Fall) in at least sixty years, Darwin it coolest May on record and yet we are rushing headlong towards "pricing carbon" to keep the temperature down. On wet weather, the BOM produced a report indicating that 1974 was at least as wet in SE QLD as the recent events and that it was probably wetter Australia-wide in '74 (the last time that Lake Eyre overflowed). This is a long report but worth reading, if only to note the rainfall map: www.bom.gov.au/hydro/flood/qld/fld_reports/brisbane_jan1974.pdfAlso ..... www.bom.gov.au/lam/climate/levelthree/c20thc/flood7.htmI don't see much different in our weather / climate except that it makes the news media much more quickly nowdays.

I agree with what you're saying in real terms with the cyclical nature of weather, on the other hand the upturn in precipitation and slight downturn in heat are delicious to watch in pure make the propagandists squirm terms.
