Weather: How accurate is long range Almanac forecasting?
Posted By RichC on July 20, 2025
The different Almanac forecasts have always interested me. They always seem to be part mystical science and crafty word selection? Who knows, but I still enjoy reading whatever version of almanacs that are available … but I do miss the paper versions. 😊
Generally, Claude.AI has not been my AI choice … but this question gave me an excuse to ask and see what it might think:
Overall, while the almanacs have cultural significance and occasionally make accurate predictions, scientific analysis suggests their long-term weather forecasting accuracy is no better than chance – around 50% – despite their claims of 80% accuracy.
