In the hills of Radnorshire. That's the middle of Wales!!
Being about 800ft up makes a hell of a difference, also on the side of a valley (rises to about 1100ft above the house) we are quite sheltered and the frosts form and roll down the hill and catch the garden as they go through.
August frosts are quite rare and short lived - but play havoc as nobody expects them, but it's normal to have some in September. June is a bad month for frost and we are lucky if July doesn't hit everything.
Learn to live with them, paranoid weather forecast watching when the veg plants all go out in the spring :w00t:.
