Our league has finished and its appears most people have packed up as well. Why?
September is a far better month weather wise than April. Average high temperatures fall from 21c to 17c but April is only 11-15c. Indeed you have to go to mid October before finding comparable temperatures to our traditional start in mid April. It rains less in September as well. The wickets are harder after 6 months warm weather. The only minor issue is the light, but just start earlier, many leagues do this already.
My gut feel is most people has a preconceived view of when the season should start and end. Very few look at the realities of global warming or simply the weather outside. Some people say they lose people to winter sports, but surely no more so than April when they are still playing.
If clubs looked to play in September, it would be in better weather ,played on better decks and they would earn more revenue. Leagues have a part to play in moving fixtures into September but in these hard times clubs are missing a trick by not doing it themselves.
