The sky over Northumberland National Park is as dark as at neighbouring Kielder, but there are more clear nights here. Of the two parks, this is the one to travel to, and winter is the better season.
Northumberland and Kielder
In this site’s data, the national park is listed as a dark-sky park. It is darker than 82% of Europe’s land, its light pollution is “very dark”, and it clocks up 176 clear moonless dark hours a year. Kielder Water & Forest Park, 27 km away, holds International Dark Sky Park status too and is likewise darker than 82% of Europe’s land, but it gets 135 clear hours: 41 fewer.
Winter nights 2026–2027
December brings 27 clear dark hours and 18% good nights, while in June and July there is no astronomical darkness. The first convenient night: the Leonids on 17–18 November 2026, with a 35% chance of a clear peak night, but the Moon is 55% lit. Better are the new moon night of 8–9 December 2026 (12.2 moonless dark hours) and the Quadrantids on 3–4 January 2027: a 37% chance, the Moon 13% lit, 13.2 moonless hours. This is the climate of 2006–2025, not a forecast (methodology).
