Plant out after the last frost

This is something we have not done. Currently, in our vegetable bed sit 6 courgette plants, runner beans (already taken a beating from the wind), borlotti beans and one spaghetti squash (which has already produced a female flower and has no male flowers to fertilise it). And tonight, 3rd May, the temperature is predicted to fall to 3 degrees. A valuable lesson in gardening is about to be learned.

Here is the veg patch. Will it still look like this tomorrow?
