Broad beans are hardy, so if/when this rain stops, they can be planted out. BUT because they have been started off inside, they MUST be hardened off first- ie gradually used to being outside.Allow about a week or so & dont plant out if frosty.
If you've no coldframe or suchlike, then you could try putting their pots next to a sheltered house wall & possibly cover with a leaning piece of glass/polycarbonate to start with. That way they get used to colder temperatures, but will get more light which they will need.
Sweetpeas also will need hardening off,. but not planting out until spring. J.
