The 208-year-old Maine-based Farmers’ Almanac says it will publish its planting guidance and weather predictions for the final time, citing financial challenges. The Farmers’ Almanac is not to be confused with its older, longtime competitor, The Old Farmer’s Almanac from neighboring New Hampshire. Both publications used secret formulas based on sunspots, planetary positions and lunar cycles to generate long-range weather forecasts. Studies found them to be a little more than 50% accurate, or slightly better than random chance. Still, many readers considered the almanacs a quaint relic with a special kind of charm. The Farmers’ Almanac said Thursday that its 2026 edition will be its last.
