[Rosie] Katoomba? About 1000 metres, give or take a few. It's not particularly elevated in world terms but is in those of Australia. I'm approximately 270 m.a.s.l. (which is close to, but not quite, 1000' a.s.l.). Please keep in mind that Mt. Kosciuszko, our highest point, is a mere 2228 metres above sea level and that you can pretty well drive there.
Last night was 'nippy' here - about 2.5°C - and as I write it seems about 11°C (it's approx 13:30 local). That reading comes from an electronic device and one in which I invest little credibility - though it's probably close. Whatever, it most surely is cold for this part of the world.

[Dujon] PaulWay is in the Caribbean at the moment, or possibly the west coast of the US.

*is not jealous of the antipodeans' sub-10-degree-centigrade temperatures at all, oh no...* 20 degrees C here (NW London) at 09.00 this morning, with a high of 32C or 90F expected today. Thank goodness I'm working outside for the next couple of days. I think...

(Dujon) Thanks. Along with penelope I could do with a bit of that. Just popped out to the screen - it's 29°, dewpoint 17°, i.e. sweaty. Almost no wind and the sky is full of heavy cirrus, which should stop it getting any hotter but might stop it cooling down much this evening, alas. Tomorrow's forecast is for all hell to be let loose (thunderstorms). It looks rather tasty, but we'll see. Only 6 mm rain here this month. Good, no gardening needed. Concerning my earlier rant my sources in the Met Office seem to have been reliable; see http://northtonight.grampiantv.co.uk/content/default.asp?page=s1_1_1&newsid=6898 You can get UK Met Office charts but only via the University of Karlsruhe.

[Pen] Bah! Luxury. It has topped 32^oC every day (Except Weds)this week here in the Avon Valley. 19^oC ish at night. I have been sleeping out on the lawn (in my sleeping bag) all week - listening to the hedgehogs fan themselves.
