In the October 1981 issue of Weatherwise, pages 212-215, John E. Walsh and David Allen performed a check on the accuracy of 60 monthly forecasts of temperature and precipitation from the Old Farmer's Almanac at 32 stations in the U.S. They found that 50.7 percent of the monthly temperature forecasts and 51.9 percent of the precipitation forecasts verified with the correct sign. These may be compared with the 50 percent success rate expected by chance.
