Can you see the northern lights in Reykjavík tonight?

Unlikely tonight — dark from 20:36 and the sky is clear, but the field is quiet (Kp 0.00).

Checked against NOAA SWPC and the MET Norway Locationforecast.

Tonight Reykjavík is 6 of 13 on the ranked table of places.

Unlike destinations with polar night, Iceland's capital Reykjavík sees sunrise year-round and sits south of the Arctic Circle, needing around Kp 2 activity to show northern lights.

Astronomical darkness (the sun more than 18° below the horizon), Reykjavík local time, computed here from the date and the coordinates.

Visit Reykjavík describes the city as the world's northernmost capital, located directly beneath the auroral oval. Visit Iceland says you need darkness and clear skies, or at least openings in the cloud cover, and that sightings are greatly improved outside populated areas away from the capital's light pollution. Visit Iceland notes that there are no guarantees with the northern lights, so staying several nights gives you more opportunities for clear skies and favourable aurora activity.

When to see the northern lights in Reykjavík

Visit Iceland, the official travel guide of Iceland, gives the best time to see the northern lights as winter, between September and April, when dark and long nights have replaced the bright summer nights. Visit Reykjavík says that in summer the bright night sky makes sightings impossible, even when auroral activity is present. You can check how long the nights are across these months, or compare with Tromsø northern lights or night length in Akureyri in the north of Iceland.

Visit Iceland says the lights are said to be most active around the September and March equinoxes, but that the chances also improve in mid-winter, which brings more darkness. Visit Iceland says you need darkness and clear skies, or at least openings in the cloud cover, and that you can check weather conditions, cloud cover and aurora activity on the Icelandic Met Office website.

Visit Iceland says there are no guarantees with the northern lights, so the more nights you have, the better your chances; staying several nights gives you more opportunities for clear skies and favourable aurora activity.

The Icelandic Met Office says the aurora requires dark and partly clear skies. On its aurora forecast page, the map of Iceland shows a forecast of cloud cover, with green areas cloudy and white areas clear.

How to get to Reykjavík

Visit Reykjavík says Keflavík Airport is about 50 km from Reykjavík. Visit Reykjavík says several car rental companies operate directly from Keflavík Airport.

Visit Reykjavík says Flybus, operated by Icelandia, offers regular connections timed with arriving flights, with a choice of coach transfers, shared door-to-door shuttles or private rides, and drop-offs at central Reykjavík stops, selected hotels and guesthouses. Isavia says Flybus leaves Keflavík Airport for the BSÍ bus terminal in Reykjavík 40 minutes after each plane lands, stopping at Aktu taktu in Garðabær and Fjörukráin in Hafnarfjörður on the way. Isavia gives the Flybus journey to Reykjavík as 45 minutes and suggests booking in advance.

Strætó's public bus route 55 runs between the capital area and Keflavík Airport every day of the week. Strætó says not all airport bus trips drive to and from BSÍ in Reykjavík; some drive to and from Fjörður in Hafnarfjörður, so remember to check the timetable.

Where to stand to see the aurora

Visit Iceland says that in most cases sightings are greatly improved outside populated areas, especially away from the capital's light pollution, and that excursion leaders are skilled at hunting the lights, finding where conditions are best on any given night.

Visit Reykjavík says the yellow city buses run until around midnight and the Strætó app finds routes to Grótta or Elliðaárdalur; for the more remote spots, such as Heiðmörk or the lakes, a car is essential.

Visit Reykjavík says you can see the lights without a tour by renting a car, checking the forecast and driving outside the city, but to be cautious on icy roads. Visit Reykjavík advises dressing in layers, because you will be standing still in the cold for long periods, and bringing a red headlamp, because red light preserves your night vision while letting you move safely. Visit Reykjavík says most tour operators offer a free retry if the lights do not appear on your first night, so it is a good idea to book your tour at the start of your trip.

Where to watch near Reykjavík

What the numbers mean

Four things have to line up before you see anything, and three of them are on this page above. The fourth is your own eyes adjusting, which takes about twenty minutes in real darkness and does not survive a glance at a phone.

Darkness comes first because it cannot be argued with. The aurora is always there when the field is active; you can only see it once the sun is more than 18° below the horizon, which is what the dark band above marks. In Reykjavík that is 9 hours and 18 minutes tonight.

Kp is a global index of how disturbed the Earth's magnetic field is, from 0 to 9, published every three hours. It is a blunt instrument: it says the whole planet was disturbed, not that the aurora is over Reykjavík now. At 64°N the auroral oval usually sits overhead already, so a quiet Kp is no reason to stay in.

The local disturbance is the better number, and it is the one most aurora pages do not have. FMI runs magnetometers across Lapland; we take the rate of change of the horizontal field at the nearest one, in nanotesla per minute. Reykjavík has none within 120 km, so its verdict rests on Kp and OVATION. A field moving fast overhead means current flowing overhead, which is the aurora itself. Above roughly 40 nT/min it is usually visible; above 100 a substorm is running and it will be moving.

Cloud ends most attempts. The figure above is the total cloud cover MET Norway's Locationforecast forecasts for the dark hours, at these exact coordinates. Anything over about 70% and you will not see through it; under 30% and it stops mattering.

The moon does not stop the aurora. A full moon high in the sky washes out the faint green arcs that make up most displays, so a strong night still shows and a marginal one does not.
