The weather seems unpredicatable but it was something we looked up before selecting a new home. As others have said in this thread and many other posts the weather can really challenge a smallholder and can make life pretty miserable.
We could not afford what we wanted in England and I had concerns about the lack of winter light in Scotland. Wales seemed too wet.
We opted for a fantastic plot in mid France. The growing season is longer and although it can be very hot or very cold with bouts of torrential rain we don't seem to have sustained perriods of grey and drizzle. We have had little rain these last few months and watering the veg plot has been a daily job. Odd as a precipitation map for our area shows us to have about 1600 - 1800 mm a year.
Maybe we should warn people to research the local climate as a priority if they are thinking of starting a smallholding - even though the weather seems less predicatble these days. Victorian Farmer could offer home seekers researched historical weather reports before they buy.
