what is the average temperature in the uk in winter
Climate of the United Kingdom Mean winter temperatures in the UK are most influenced by proximity to the sea. The coldest areas are the mountains of Wales and northern England, and inland areas of Scotland, averaging −3.6 to 2.3 °C (25.5 to 36.1 °F).[28] Coastal areas, particularly those in the south and west, experience the mildest winters, on average 5 to 8.7 °C (41.0 to 47.7 °F).[28] Hardiness zones in the UK are high, ranging from zone 7 in the Scottish Highlands, the Pennines and Snowdonia, to zone 10 on the Isles of Scilly. Most of the UK lies in zones 8 or 9.[29] In zone 7, the average lowest temperature each year is between −17.7 and −12.3 °C (0.1 and 9.9 °F), and in zone 10, this figure is between −1.1 and 4.4 °C (30.0 and 39.9 °F).[30]
Room temperature Owing to variations in humidity and likely clothing, recommendations for summer and winter may vary; a suggested typical range for summer is 23 to 25.5 °C (73 to 78 °F), with that for winter being 20 to 23.5 °C (68 to 74 °F),[5] although by other considerations the maximum should be below 24 °C (75 °F) – and to avoid sick building syndrome, below 22 °C (72 °F).[5]
