What Kp is needed here?

Devon sits at a magnetic latitude of approximately 51°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 6–7 before the auroral oval expands far enough south to be visible from here.

At Kp 6–7, visibility is possible from Devon but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.

Best dark sky sites near Devon

Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.

Dartmoor Dark Sky Reserve - Yes Tor and High Willhays

Get directions ↗
Bortle Class 2 - Excellent dark sky 30 km from Exeter - approximately 40 minute drive to Meldon car park

Dartmoor National Park holds International Dark Sky Reserve status - one of only a handful in England. Yes Tor (619 m) and High Willhays (621 m) are the highest points in southern England and sit above cloud inversions that often affect the Devon coasts. The western moor accessed from the Meldon reservoir approach is Bortle 2 in all directions on clear nights with no settlements visible from the summit plateau. The open granite moorland gives a 360-degree sky view. During G3+ storms, aurora appears clearly above the northern horizon from the summit tor, with the dark moorland as a foreground.

Baggy Point, north Devon coast

Bortle Class 3 - Rural sky, good dark sky 55 km from Exeter - approximately 1 hour drive

A National Trust headland on the north Devon coast near Croyde, facing directly north across the Bristol Channel and the open Atlantic beyond. The headland is dark in its north-facing aspect with only Croyde village lighting visible to the south-east. The cliff-top path gives access to positions with a clear northern horizon above the sea. The Bristol Channel is wide enough here that no Welsh coast lighting appears on the northern horizon. On a Kp 6-7 night, this is Devon's best north-facing coastal position.

Haytor and the eastern Dartmoor fringe

Get directions ↗
Bortle Class 3 - Rural sky, good dark sky 25 km from Exeter - approximately 30 minute drive

Haytor Rocks on the eastern edge of Dartmoor are accessible by car with a large car park off the B3387. At 457 m, the tor sits above the Teign Valley and gives a wide north-facing view across the moor. Sky brightness here is Bortle 3 - darker than Exeter but not as dark as the western moor. The granite tor provides a foreground that's recognisable to most visitors, making it a popular aurora photography target during major events. Torchwick and the Hay Tor vale below give a natural dark foreground for wider shots.

When to go

Best time to see the northern lights in Devon

At 51°N magnetic latitude, Devon sits at the lower end of regular aurora territory. Only the deep mid-winter months of November through January offer nights dark enough for aurora to be visible, and only then when a significant geomagnetic storm pushes the auroral oval this far south.

Activity peaks around the September and March equinoxes, when Earth's magnetic field geometry is most favourable for coupling with the solar wind. Events during these two windows tend to produce the strongest displays of the year for observers at Devon's latitude.

Outside November through January, twilight is too bright for aurora viewing even during significant storms. The season is short, but the equinox months on either side of winter can extend it slightly when storm timing aligns.

Questions

Common questions about aurora in Devon

Can you see the northern lights from Devon?
Yes, from dark sites during strong geomagnetic storms. Devon sits at roughly 51°N magnetic latitude, requiring Kp 6-7 for aurora to reach its skies from a dark position. Dartmoor National Park is an International Dark Sky Reserve with Bortle 2 conditions, making it the best aurora site in southern England by sky quality. During the G5 storm of May 2024, aurora was photographed from Dartmoor and north Devon. During typical moderate storms (Kp 5), Devon will not see aurora.
What Kp is needed for aurora in Devon?
Kp 6-7 from dark sites on Dartmoor and the north Devon coast. Devon sits at approximately 51°N magnetic latitude. The auroral oval needs to expand significantly south from its resting position. At Kp 6, a faint arc may appear from the darkest Dartmoor positions. At Kp 7, structure becomes visible. At Kp 8-9, aurora is visible from anywhere in Devon with clear sky. The elevation advantage of Dartmoor - which sits above cloud inversions - makes it the most reliable position for early detection at the threshold.
Is Dartmoor a good place for aurora?
Dartmoor is one of England's best aurora positions by sky quality. Its International Dark Sky Reserve status comes with Bortle 2 conditions across the higher western moor - comparable to remote Highland positions in terms of sky brightness, though the latitude requires a stronger storm. The elevation above sea level (600 m on the high moor) regularly places the observer above coastal cloud layers. Yes Tor and High Willhays give a 360-degree dark sky horizon. The limitation is magnetic latitude: Dartmoor needs G2-G3 minimum.
How does Devon compare to Exmoor for aurora?
Exmoor sits at roughly 51°N magnetic latitude and holds International Dark Sky Reserve status, making it comparable to Dartmoor in both position and sky quality. Dartmoor has an advantage in elevation - its high points at 620 m exceed Exmoor's highest at 520 m - which helps in cloud avoidance. Exmoor's north coast gives a north-facing Bristol Channel horizon that Dartmoor lacks, which is an advantage for low aurora arcs. Both are valid targets during G3+ storms. In practice, the choice comes down to which side you approach from - Exmoor from Bristol and Somerset, Dartmoor from Exeter and Plymouth.
When is the best time to see aurora from Devon?
September to March, with September and March historically the most geomagnetically active months. Devon has adequate darkness from late August. Winter nights extend to about 15 hours near the December solstice. The south-west has a maritime climate with frequent cloud, particularly from Atlantic fronts in autumn. The Dartmoor summit plateau is often above the cloud inversion when the coasts are covered, making it the most reliable position in marginal conditions.
