Hi Ben,
31 C, that was high, when we start here in August we have about 15 C degrees, but it's not dark enough then, better in middle of september and then it has cold down to about 5 to 10 C degrees. Not very big problem with the cameras at that temperature, even an uncoold DSLR works relative good, but even better at zero degrees of course.
The only thing I do in August is watching for the Perseids meteor shower. This how it could be when watching Perseids:

There is an Timo who writes at the Swedish forums that he go to Australia sometimes. We all like kanelbullar :-)
