Storm level needed
Malahide sits at 53.45N 6.15W in Leinster, Ireland. The IGRF-14 centered dipole puts Malahide at 56.2 degrees geomagnetic latitude, 2.7 degrees closer to the magnetic pole than its map latitude suggests. Malahide sits at 56.2 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
"aurora is commonly visible at high latitudes (northern Michigan and Maine)"
The nearest other Glow towns are Dublin (15 km), Balbriggan (18 km), Bray (28 km). Dublin sits 0.1 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 Malahide has some civil darkness; the shortest month sample still has 5.1 hours. Every evening of the year at Malahide clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Malahide's longest night of the year, Dec 18, has 14 h 58 min of civil night.
Solar midnight at Malahide, when the sun is lowest, falls at 00:20 on local clocks on December 15 and 01:25 on June 15. That is 20 min after midnight in December and 1 h 25 min after midnight in June, the gap set by daylight saving and the equation of time. So at Malahide the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

By the 15th-of-the-month sample, December is the darkest month at Malahide with 14.9 hours of civil night and June the lightest at 5.1. Across the year Malahide gets 3,731 hours of civil night. Astronomical night at Malahide, the sun 18 degrees or more below the horizon, lasts 12.0 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Malahide at 75% across the year, from 73% in April to 78% in January. In the months with at least 4 hours of civil night Malahide averages 75%, against a median of 75% for Glow towns in Ireland.
Multiplying civil night by the clear share of the sky gives November the best score, 3.8 hours, ahead of December at 3.6. Malahide's equinox months score 2.8 in March and 2.6 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 5 or more, the level that puts the average oval edge over Malahide, on 10% of days. At Malahide's level the share runs from 5% in December to 14% in September, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 2, the new moon falls on Oct 10 and the full moon on Oct 26, in Europe/Dublin dates. 15 of the 30 nights at Malahide have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Malahide has 11 h 15 min of civil night, 2 h 7 min of it with the moon down.

Questions
- Can you see the northern lights in Malahide?
- Malahide sits at 56.2 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less. Clear, dark sky over Malahide still decides it.
- When is it dark enough in Malahide?
- Every night at Malahide has civil darkness. Tonight has 11 h 15 min, and December 15 has 14.9 hours.
- What is the best month for aurora in Malahide?
- November, by civil night at Malahide times the clear share of the sky from NASA POWER's 2001 to 2020 average.
- How cloudy is Malahide in the dark months?
- About 75% mean cloud amount over Malahide in the months with at least 4 hours of civil night, from NASA POWER's 2001 to 2020 all-hours climatology.
- How often is activity high enough for Malahide?
- A 3-hour Kp of 5 or more, the level that puts the average oval edge overhead, occurred on 10% of days from 1996 to 2025 in the GFZ Potsdam record.
- Why does this page point to Dublin?
- Malahide sits within 15 km of Dublin with the same rounded dipole latitude, Kp and dark season, so Glow treats Dublin as the main page for both.
