Latest date with a high temperature at or below 0º Celsius: A.D. 2009 April 07F***ing hot. Three days ago the high temperature was between 8º and 9º Celsius (46º-48º F.). Two days ago it snowed. Yesterday morning we had a light frost. Today the temperature is already 30º Celsius (86º Fahrenheit) in the shade. The roads are clogged with people. Two thoughts have been bouncing around my mind: I forgot how much I dislike summer (too many people; too hot) and I want a sailboat.
I didn't start keeping track of the last hard frost until after we stopped having them. We had something like 11 hard frosts in 13 days so I decided to stop worrying until later in the month. We've only had one or two since then, so my statistics aren't perfect. It's very likely that we had a hard frost on A.D. 2009 April 16. It's a little less likely (but still likely) that we had one on A.D. 2009 April 17. I'm hoping that we'll have another one, but the long-term forecast doesn't look good. In any case, I'm leaving the date of April 13 for now.
