All 12 months are shown. “Insufficient data” means fewer than three years meet 70% hourly coverage for that calendar month. Winter months use the same coverage rules; they are not deliberately excluded.
Hourly UTC observations, at least 70% coverage per station-month-year and at least three qualifying years per calendar month; 10th–90th percentiles of qualifying hourly observations.
