When is the danger of frost past?

[HKCambridge]

Title says it all: how do I know when the danger of frost is past?

If it helps the plants I'm thinking of keeping outside full time now are tomatoes, courgettes, chillis and raspberries. I've been leaving them out in daylight and bringing them inside for about a week and I'd like to be able to leave them outside full time now. Also ready to plant out chitted charlotte potatoes if its warm enough.

I take things inside at night until mid May. Sounds pessimistic but I've lost toms in my cold greenhouse otherwise.

Toms, squash and chillies are all 'tropical'...I wouldn't put them o/s until end of May.
Raspberries are hardy... why have you got them indoors?
Your potatoes can probably be planted out...mine have all gone in this w/e

Last frost can vary by area HKCambridge. Might be mid May some areas and end of May in others. Our 30 year average is the end of May, although we haven't had a frost after the first week in May for the last 8 years. You could check up on your local area.
You could put your plants outside during the day in fine weather and take them in at night. Your raspberries are perfectly hardy. If they've been mollycoddled, I would harden them off and plant them.

Our last frost is second week in April. Thank you, salty sea air!

Lucky you, Two Sheds.

The old adage "Ne'er cast a clout 'til May be out" probably applies (sorry if I got all the puncuation/spelling wrong).

If your local May trees are in flower you are unlikely (please note only unlikely!) to have any more frost. Don't ask me how the tree knows - one of this worlds mysteries!

[Flummery]

And our May buds are as tight as a fishes bottom at the mo. It's going to be mid-end May again here methinks!

Thanks

I can remember the year a Derbyshire cricket match was snowed off on May 9th
The year 1976!!!
