Dreich weather.
But the first frosts should have sweetened the swedes - just in time for heartening winter stews and soups; the leeks, and brussels sprouts are starting to come into their own - and there may be a few surprisingly hardy "summer" brassicas still cropping.
If you are prepared to run the risk of losing plants, it is time to sow winter hardy broad beans (like Aquadulce) and peas (like Feltham Firsts) so that you have very early harvests next year - untouched by pest and disease. Probably a bit late to sow garlic though - it is more likely to rot.
