Notes
These estimates of 30-year averages are interpolated from values on a regular grid derived from station observations. Where relevant and possible the effects of altitude, urban areas and proximity to the coast are taken into account.
Local effects are not taken into account in producing these estimates. As a general rule this makes them less accurate in mountainous areas. In particular, days of thunder, hail, snow falling and snow lying may be unreliable in data-sparse areas such as central and northern Scotland.
Estimates are available for 1961-1990 for all the climate variables shown in the example.
Estimates are also available for 1971-2000 for most of the climate variables. However, Highest max °C, Lowest min °C, Lowest max °C, Highest min °C, Min hourly RH %, Max hourly RH % will not be included.
