Northern lights in Devon tonight
Devon · 51° magnetic latitude · Kp 6–7 threshold
Kp 6 is below the threshold for Devon. Activity would need to rise to Kp 6–7 before aurora could reach this latitude.

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 ↗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
Get directions ↗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 ↗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.
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.

How often does the aurora appear in Devon?
Average nights per month the Kp reached Devon's threshold of 6+, from 15 years of geomagnetic data (2010–2024).
Counts the Kp 6+ threshold only - cloud cover and local darkness are not included.
