Have a Look at This

I stumbled across this site on one of my internet rambles. It's aimed at the US , but some of the information is very useful.

I subscribe to that almanac in its printed version.

Their weather forecasts have over 80% accuracy rate, based on historical data and mathematical probabilities, while our scientists at the National Weather Service, using tracking satellites and the most advanced computer modeling, have just over 50% accuracy rate.

They also have very good planting and harvest data along with miscellaneous trivia and bits of history.
