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?
