Es (sporadic E) propagation

Although in the northern hemisphere this tends to be best around May-August, it can occur at any time of the year bringing huge ranges on the VHF bands.  There tends to be a smaller peak around December-January.

Southgate News has a link to a piece on Es. In my view, despite having experience of Es since (at least) the 1930s, the world still has much to learn about it.
