We had -32C here on the 6th of Jan 2009. Killed off all my evergreen viburnums, an eleagnus, a choisya, several dwarf conifers, lots of clems including all the alpinas, montanas and macropetalas, New Dawn and Guninées rose and cut my whopping great Kiftsgate back to one surviving stem about 6' high.
We've had the more usual -20Cs since then and the last two winters have hardly had any frost worth mentioning so Kiftsgate has finally recovered and is covering the front, south facing wall of the house beautifully again. It's been so cool and wet for a month or more that it's only just opening its flowers now - about 3 weeks later than usual.
The hottest I have ever been was 42C in the shade at Uluru but that's dry heat and do-able. I'm not good in sticky heat.
