Record-breaking hot March weather
It looks like summer has arrived early in the UK with record-breaking temperatures in Scotland today and over the weekend.
It got as hot as 22.9C in Aberdeenshire today, beating Sunday's record temperature for March of 22.8C.
The previous record for Scotland was 22.2C way back in March 1965.
It's really warm all around the UK, and at the weekend beaches and parks filled up with people looking to make the most of the sunshine.
And it's not over yet.
Weather forecasters say the sun is going to stick around for most of the week.
Plus, the clocks went forward this weekend meaning we get an extra hour of daylight in the evenings as well.
We asked you what you've been doing in the sun. Here's a selection of some of your comments.
