Northern Lights in the UK: When & Where to See Them (2026)

By Alexander Merz · Updated on 3 August 2026 · Details checked on 5 October 2026

For decades, the northern lights were seen as a privilege reserved for travellers heading to Iceland or Norway. But since the Sun entered its activity maximum in 2024, that has changed: on several occasions the sky glowed red and green as far south as southern England and central Europe. Millions of people across the UK and Europe saw their first aurora in 2024 and 2025, right from their back gardens. And the odds remain excellent. Here’s when and where you can see the northern lights in the UK and Europe, how the forecast works, and how to nail the photo.

How do the northern lights form?

The Sun constantly hurls charged particles into space – the solar wind. During solar flares and so-called coronal mass ejections (CMEs), an especially dense cloud of particles races toward Earth. Our planet’s magnetic field funnels these particles toward the poles, where they strike the atmosphere at roughly 100 to 400 kilometres up: oxygen glows green (lower down) and red (higher up), while nitrogen shines violet-blue.

What matters for mid-latitude Europe: the stronger the storm, the further the “auroral oval” stretches south. At our latitudes we mostly see the red high-atmosphere component above the northern horizon – during extreme storms like May 2024, the glow stood right at the zenith over London, Manchester and even northern France.

When are the chances best?

• Solar activity: Solar Cycle 25 peaked in 2024 – the years through roughly 2027 will stay above average. Right now is the best window in two decades.
• Season: Around the equinoxes (March/April and September/October), geomagnetic storms are statistically most frequent. In high summer the bright nights get in the way; in winter the long nights help.
• Time of night: Usually between 10 pm and 2 am – but storms don’t keep to a timetable. The live alert is what counts.
• Moon: Nights near the new Moon reveal even faint aurorae – our Moon calendar shows you the dark nights.

The Kp index: how to read the forecast

Forecast sources: NOAA (the US space-weather agency) provides a 3-day forecast, and European services such as the Met Office and AuroraWatch UK turn it into concrete warnings with app alerts. Rule of thumb: once a Kp 6–7 is forecast it’s worth heading out; from Kp 8, drop everything and find a dark sky.

The right location and how to observe

• An open, dark northern horizon – get out of town; light pollution toward the north is the most common spoiler (more on this: light pollution).
• Let your eyes adapt for 20–30 minutes – no phone screen (or use red-light mode).
• Patience: the aurora comes in waves (“substorms”) – often a faint glow for 20 minutes, then the sky erupts for ten minutes.
• No binoculars needed! The northern lights are a naked-eye event – your eyes (and the camera) are more than enough.

While you wait for the storm to fire up, a pair of wide-field binoculars is the ideal companion for sweeping the Milky Way and picking out star clusters. They won’t help with the aurora itself – it’s simply too vast – but they turn the long minutes of waiting into a proper night under the stars.

Why the camera sees more than you do

Our night vision is almost colour-blind – faint aurorae look like grey veils to the eye. A camera (or your smartphone’s night mode!) instead gathers several seconds of light and reveals saturated green and red. So the rule is: when in doubt, photograph toward the north – if colour shows up in the frame, an aurora is under way. The full guide, with all the settings for iPhone, Samsung and DSLR, is in our article on photographing the northern lights – round it off with smartphone astrophotography.

Frequently asked questions about the northern lights

Can you really see the northern lights in the UK?

Yes – in May and October 2024 the UK had the strongest displays in decades, visible right down to the south coast. From Kp 7 upward, anyone with a dark northern horizon has a chance.

How often do the northern lights appear over the UK?

In active years like now: several times a year with the naked eye, and almost monthly on camera in the north. During quiet solar years, entire years can pass without a sighting – so make the most of the current activity phase!

What time of night is best?

Statistically 10 pm to 2 am, but the storm’s timing is what matters. A forecast alert (an app or a dedicated service) beats any fixed time-of-night rule.

Do you need a telescope for the northern lights?

No – aurorae fill half the sky, so a telescope would be counterproductive. If you want to explore the starry sky while you wait, our monthly guide shows what’s visible right now.
