Climate

Worked out for one point: the average position of Powys's postcodes, near Llanbister. Across an authority the climate can differ by a degree or two, more on high ground and by the sea.

Over 1991 to 2020, July days here averaged a high of 19°C, and February nights a low of 0°C. About 1,225 mm of rain fell in a year, most in December. A typical year had 67 days of air frost and 4 days above 25°C, and 38 days with 10 mm of rain or more.

Source: Met Office, HadUK-Grid climate averages for 1991 to 2020, from weather station records spread onto a grid. Rainfall, frost and summer days are for the 2 km square around the middle of Powys's homes, near Llanbister; daily highs and lows are published for 12 km squares only, so they have been moved by the difference between the 2 km square's average temperature and the 12 km square's. These are long-term averages, not a forecast: recent years have been warmer, and a valley bottom or a hilltop in the same square can differ by a degree or two.

Daylight through the year

On the shortest day, 21 December, the sun rises at 08:20 and sets at 16:02: 7 h 41 min of daylight. On the longest, 21 June, it rises at 04:51 and sets at 21:39: 16 h 48 min.

Worked out from the latitude and longitude of the middle of Powys's homes, near Llanbister, in UK clock time (British Summer Time from the last Sunday in March to the last Sunday in October), for flat ground with a clear horizon. Hills, buildings and trees make the sun appear later and set earlier, and which way the windows face decides how much of it comes in.

Earthquakes

Since 1970 the British Geological Survey has recorded 37 earthquakes of magnitude 2 or more within 50 km (31 miles) of the middle of Powys's homes, near Llanbister; 5 of them were magnitude 3 or more, and 1 magnitude 4 or more. The largest was magnitude 5.1, centred near Bishop's Castle, Shrops, 23.7 km (15 miles) north-east, on 2 April 1990. The most recent was magnitude 2.7, near Llanbister, Powys, on 12 May 2026.

What the sizes mean: magnitude 2 is rarely felt and is found by instruments; magnitude 3 is often felt close by, like a heavy lorry passing, and does no harm; magnitude 4 is felt widely and can rattle windows and knock things off shelves, occasionally cracking plaster near the centre; magnitude 5 or more is rare in Britain, a few in fifty years, and can damage chimneys and old walls close to the centre. Each step up is about 30 times more energy.
