Tromsø's Polar Night: No Sun, But Not Total Darkness for Months
Residents of **Tromsø, Norway (69.6°N)** do **not** go months without *any* daylight. The reality is more nuanced:
Polar Night (Mørketid): Nov 27 – Jan 15 (~7 weeks)
- Sun remains below horizon.
- But: Civil twilight (sun < 6° below) occurs daily ~9 AM – 2 PM. Sky is deep blue; outdoor activity possible without artificial light.
- Nautical twilight (6°–12°) extends usable light further.
What "No Sunset" Means
- Midnight Sun (Midnattsol): May 18 – Jul 26 (~10 weeks). Sun doesn't set.
- Polar Night: Sun doesn't *rise*—but **twilight persists**.
