On this day
Pick one calendar date and see the all-time record high, low, rainfall, and snowfall for that date across every year on record.
Example: December 25 → the coldest, hottest, wettest, and snowiest Christmas Day ever recorded.
Date Range Stretch
Pick a calendar-day stretch (e.g. Jul 1–5) and rank every year's occurrence of it by hottest, coldest, warmest, rainiest, and snowiest.
Example: July 1–5 → which year had the hottest opening week of July?
Daily Extremes
The top N highest or lowest values ever recorded for one metric, optionally narrowed to a month/season and a specific year.
Example: Highest temp max, all time → the hottest days Boston has ever recorded.
Streaks
The longest (or most recent) consecutive-day runs where a metric stayed above or below a threshold.
Example: Temp max above 90°F → the longest heat wave on record.
Streaks (Range)
Like Streaks, but for consecutive seasons instead of days — finds runs of years where a custom month range's (e.g. Oct–Apr) total for a metric crossed a threshold.
Example: Snowfall total above 60in, Oct–Apr → winters in a row with 60+ inches of snow.
Streaks (Departure)
Finds runs of consecutive months or years (toggle between the two) where a metric ran above or below normal — not a fixed threshold, but a comparison to what's typical. Months compare against that same calendar month's average; years compare against the all-time yearly average.
Example: Precipitation below normal, Months → the longest streak of months in a row drier than usual.
First per year
The earliest date each year (or fall/winter season, for snow and cold metrics) that a metric first crossed a threshold.
Example: Temp min below 32°F → the earliest first frost each fall.
Season totals
Total precipitation or snowfall summed over a custom month range (e.g. Dec–Feb), ranked across every year/season on record.
Example: Snowfall, Dec–Feb → the snowiest winters on record.
Count Before Date
Counts how many days per year met a threshold — optionally counting only through a cutoff date rather than the whole year — ranked across years.
Example: Temp max above 90°F, before July 1 → years with the most 90° days by early summer.
