I've known snow in June, and the first frost of 'winter' in late August.
Funny stuff, all this weather!!
To risk, or not to risk, that is the question?
The recent warm weather has certainly been tempting to plant stuff out, and must admit to having succumbed with a few things. Have planted out a wigwam of runner beans, in a sheltered spot, very close to the house so it can be fleeced up at the first possibility of a whiff of a frost.
I think the best advice is, by all means plant stuff out, BUT, keep an eye on the local weather forecast. If there is even the remotest possibility of frost, cover up.
Yet another couple of cliches - you win some, you lose some, but nothing ventured nothing gained, just about sums up this time of year!!
