Storm level needed
Surrey sits at 49.11N 122.83W in British Columbia, Canada. The IGRF-14 centered dipole puts Surrey at 54.4 degrees geomagnetic latitude, 5.3 degrees closer to the magnetic pole than its map latitude suggests. Surrey sits at 54.4 degrees geomagnetic. The lowest NOAA storm level whose typical viewing latitude reaches it is G3 (Kp = 7). By SWPC's rule the average oval edge is overhead only at Kp 6.
"aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)"
The nearest other Glow towns are Delta (17 km), Coquitlam (20 km), Vancouver, British Columbia (27 km). Delta sits 0.0 degrees lower on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Surrey has some civil darkness; the shortest month sample still has 6.2 hours. Every evening of the year at Surrey clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Surrey's longest night of the year, Dec 17, has 14 h 26 min of civil night.
Solar midnight at Surrey, when the sun is lowest, falls at 01:07 on local clocks on December 15 and 01:12 on June 15. That is 1 h 7 min after midnight in December and 1 h 12 min after midnight in June, the gap set by daylight saving and the equation of time. So at Surrey the darkest hour sits late in SWPC's 10 PM to 2 AM window.

By the 15th-of-the-month sample, December is the darkest month at Surrey with 14.4 hours of civil night and June the lightest at 6.2. Across the year Surrey gets 3,812 hours of civil night. Astronomical night at Surrey, the sun 18 degrees or more below the horizon, lasts 11.8 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Surrey at 71% across the year, from 50% in July to 81% in January. In the months with at least 4 hours of civil night Surrey averages 71%, against a median of 67% for Glow towns in Canada.
Multiplying civil night by the clear share of the sky gives September the best score, 4.3 hours, ahead of August at 4.2. Surrey's equinox months score 2.1 in March and 4.3 in September, the weeks SWPC links with larger storms.
Kp history
From 1996 to 2025, the GFZ Potsdam record shows a 3-hour Kp of 6 or more, the level that puts the average oval edge over Surrey, on 3% of days. At Surrey's level the share runs from 1% in December to 5% in October, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 1, the new moon falls on Oct 10 and the full moon on Oct 25, in America/Vancouver dates. 15 of the 30 nights at Surrey have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Surrey has 11 h 14 min of civil night, 1 h 55 min of it with the moon down.
