(Dujon) Doesn't the record actually say that the maximum temperature each day reached 100°F for 161 consecutive days. I can't believe that it stayed above 100°F all night, every night. That has happened very occasionally in the Sahara (and probably elsewhere) in high summer but is very rare. At the moment a temperature of 5°C would be nice. It hasn't been that high since last Sunday week and it's been down to -7°. White Christmas? No thank you. That white stuff is cold and stops you getting about.
[Rosie] As usual here in the channel we have missed the worst of it. A sprinkling last Thursday which caused mayhem on the roads and now the sun is shining and its about 7C.
Yeah. White (near-)Christmases aren't all they're cracked up to be. Though we've had some crunchy goodness here, so I've not been sliding around too much on it.
[Rosie] Possibly so, but I don't really know and thus accept the data. In Dec./Jan. 1988/9 or thereabouts I spent four or five weeks in a place called Hillston. That was a dreadful period. At a guess I'd say that I experienced 14 days of overnight temperature above 100ºF. I shall check and report back should I find any objective observations.
(Dujon) I looked at OZBOM, an excellent site, and it confirmed that it was the maxima that were all over 100°F. I suspect the minima were mostly 25° to 30°. In the last few years Adelaide has had a record high minimum of 34°C. To get a minimum of 100°F (37.8°C) you really need quite a stiff breeze to stop the lowest layers cooling and becoming decoupled from the circulation. You get a sandstorm thrown in for good measure, of course. The only place that doesn't seem to need this condition is Death Valley, where there have been several well-authenticated instances of the night minimum being above 110°F. Glad I'm not the weather observer there, or in Ojmjakon, Siberia, January mean -50°C. Yes, fifty. Wrap up well, as my Mum used to say.
[Rosie] Thank you. I must have missed that information, thanks for the clarification. As far as wrapping up well is concerned your Mum's advice sounds like it should have been originally decreed by one of those pesky Yorkshire men (before they subsisted on gravel, of course). ;)
