The analysis includes 1,125 complete 7-day periods out of 1,125 possible periods in 45 years (1981-2025), for Stockholm. Every week lies entirely within the selected month. Overlapping weeks are not independent samples. Incomplete weeks are excluded.

A matching day has a daily maximum within the selected temperature range, inclusive, and precipitation below 1 mm. Trace precipitation is possible. The typical range is the 20th-80th percentile of matching days per week. Daily percentages count each calendar day once; categories can overlap.
