Sky archive
Browse past days by date, watch a day's timelapse, and — where available — graph the weather behind it.
The Archive page searches past days by date — a year, a year and month, or a full date all work in the search box. Without a specific day selected, it shows a grid of archived days that have a timelapse, plus (when Weather is enabled) a table of recorded weather history by day.
A single day
Opening a specific day shows its timelapse video(s), a "Weather that day" summary (high, low, mean, humidity, pressure, wind, gust and rainfall) — marked as a genuine station record, or as reanalysis for older dates the station backfills from historical forecast data rather than having measured itself — and, where the station has a remote weather database connected, six collapsible charts graphing temperature, humidity and cloud, pressure, wind, rainfall, and sun and UV through that day. Stations without a remote database connected show the daily summary only, with a note that connecting one is what unlocks the hour-by-hour charts.
