Extreme Day-Night Temperature Contrast in Uruguay,

[Alfon99]

Hi, I live in Uruguay, South America and just bought a weather station, which has been working since may and It recorded very big temperature contrast between day and night. Once it recorded -3 celsius at night and in the daytime 20 celsius. The other day It was not so big, -1 celsius at night and 16 celsius in the daytime. And this morning it was 0 celsius and it went up to 17 celsius in the afternoon. What do you think?

That is quite a difference, although it's not that rare to have a range of temperatures like that. It happens in the UK too, we had something similar a few weeks ago with around 0ºC overnight and then 20ºC+ during the day. It's usually a sign of nice sunny weather (i.e. clear skies) so enjoy it while it lasts

I've experienced some pretty huge ranges in Australia in highlands (800m asl) with pretty dry environment. In late winter mins of -10 to maxs of 16-17 degrees. Similarly in summer same region have had close to 30 degree temperature range from 5-10 degrees overnight to mid 30s.

 

I think its not that uncommon in elevated and relatively arid environments.
