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 Arun's homes, near Horsemere Green; 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.

Worked out from the latitude and longitude of the middle of Arun's homes, near Horsemere Green, 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.

What this page cannot tell you

What homes are worth now: the median is of the homes that happened to sell, and a few large or new-build sales move it.
Sales from the last two months: they reach the Land Registry two weeks to two months after completion.
