Residents and weather enthusiasts in Boston will watch the overnight lows on August 16, 2026, to see if the temperature stays within particular numerical limits. The official reading from The Weather Company will be the sole determinant of the outcome.
Resolution depends on Boston’s (CLIBOS) minimum temperature on August 16, 2026, according to The Weather Company, divided into six bands: less than 54°F, 54-55°F, 56-57°F, 58-59°F, 60-61°F, and greater than 61°F. A market resolves to Yes if the recorded low falls within its specified band, otherwise No. Secondary rules clarify that The Weather Company’s data is authoritative, even if other weather services report different values.
