Frequently asked
Is tonight good for stargazing at Exmoor?
The live score above pulls today's forecast and runs it through StarCast's scoring model, factoring in cloud cover, moon illumination, Bortle class, humidity, and atmospheric transparency. Above 70 is an excellent night. Below 40, conditions are poor. The score updates daily.
What makes Exmoor good for astrophotography?
Exmoor National Park in Somerset and Devon was Europe's first International Dark Sky Reserve, designated in 2011. The park's moorland plateau, reaching 520 meters at Dunkery Beacon, is surprisingly dark for its location in southwestern England: Bristol is 60 kilometers to the northeast but is largely screened by the Mendip Hills, and Exeter produces a modest dome to the south. The Bristol Channel coastline to the north creates a dark northern horizon over water, which is unusual for an English national park. The Pinkworthy Pond, Dunkery Beacon summit, and Webber's Post are the main dark sky access points.
When is the Milky Way visible at Exmoor?
The galactic core is visible from March through October. Exmoor's southwest England position means it benefits from Atlantic airflows that can bring both cloud and, after clearance, exceptional transparency. Spring and autumn anticyclones that sit over the UK produce the clearest and most stable nights. The core's altitude in the south is limited at this latitude (51 degrees north), but the darkness of the site and the wide, open moorland horizon make it photographable from late spring through early autumn. The park's star-quality lighting ordinances keep the roads and villages dark.
