Updated daily — no account required
Every day of the year gets its own page in the SkyLog almanac: one meteorology fact worth knowing, one practical tip you can use, and — when the calendar has one — a weather event that made history on this date. The entry below is dated Monday, October 19, 2026 and changes automatically at midnight.
A lightning channel can be several kilometres long. Thunder from the part nearest you arrives first; sound from the top and far end arrives later, stretched into a rumble. Refraction through air of different temperatures bends the sound further, which is why distant lightning sometimes looks silent.
UV peaks around solar noon, commonly 12:00–14:00 local clock time. Shift workouts to early morning or late afternoon, seek tree-lined routes, and wear a cap; temperature and ozone also usually peak later, making the evening doubly easier.
There is no featured anniversary logged for today's date. The atmosphere keeps its own schedule — use today to notice the sky yourself: wind direction, cloud type at two different heights, or the exact time the sun touches the horizon.

The notes are arranged on a calendar cycle: each calendar day selects its fact and tip by the day of year, while history entries match the exact month and day. That means the page you see on any given date is different from the day before — and identical on the same date next year, like a traditional printed almanac. All notes are written and maintained by the SkyLog editorial team; none are generated on the fly, and no external service is required.
