It's just "How was the weather at your (plural) place today?". Your basic Danish attempt at talking to acquaintances you haven't seen for a long time...which never works well because Denmark is so small that the weather is pretty much the same all over the country. Also, the most common response will be "a little rainy".
Thanks for the answer.
First thing: is it a common phrasing in Danish? The English sentence seems very strange (your explanation sounds much better).
Nonsense: I don't think it's so small. Plus from my experience the weather changes every fifteen minutes so the question stays current.
