At this time of year, atmospheric effects can give stations interference problems by reflecting radio signals well beyond thier official coverage areas.

The cause is known as Sporadic E, an atmospheric effect that causes signals in the 30-300MHz range to reflect off the E layer of the Earth's atmosphere, around a hundred kilometers above Earth's surface, instead of flying through into space.
