I haven't been able to find actual human readable data for the minimum grass temperatures at Edinburgh Gogarbank. However, I did find the raw SYNOP data for 06:00 UTC this morning which I was able to find at ogimet.com. Upon decoding that data, I discovered that last night's minimum grass temperature at Edinburgh Gogarbank was -4°C which means that we did have an official ground frost there last night, even though I didn't actually manage to see any of that.
