In addition to forward looking forecasts for day to day
operations, the Met Office offers historic
weather data providing an indication of average weather
conditions at particular sites. Such data can be useful
for a variety of purposes and can lead to improved planning
and more efficient building and maintenance projects. Whether
you require daily, monthly or annual records, we can provide
quality controlled data for a variety of stations around
the UK and beyond.
|
A comprehensive range of historical weather variables are available
direct from the Met Office, which may be presented and analysed
in a number of ways. We recommend that any analysis is based on
ten years of data at least.
- Cloud base
- Visibility
- Wind direction or speed, e.g. mean speed, highest hourly mean,
highest gust
- Temperature e.g. maximum and minimum - absolute, means, lowest
and highest
- Precipitation e.g. averages, wettest, driest
- Frost, snow, thunder, hail, fog
- Metars
Climate Summaries: Means and
Extremes
A comprehensive annual, monthly, hourly or daily

Wind rose
Annual or monthly graphical representation showing
the relationship between the frequency and speed
of wind from compass point directions. By showing
you the prevailing wind at each site, the wind rose
shows how often on average problems with crosswinds
are likely to occur.
Gust maps and maximum gust analysis
are also available.
|
Frequency Analysis
Frequency and percentage occasions for customer
specified variables and each month or day, e.g.
3/8th sig cloud less than 300 & 1000ft; visibility
less than 5000m.

Standard Deviation and Post
Event analysis
Actual weather data to compare against the forecast;
and statistical records for particular weather variables.
|
Charts and graphs
At a glance climate data - some of which are available
free of charge via our Aviation
briefing service. The statistics used are derived
from weather observations made over a number of
years by meteorological observers at each airfield.
Graphs of averages are then produced which help
you understand the data.

General Monthly Summary
Basic summary of daily weather conditions by calendar
month, including monthly long-term averages. These
reports are ideal for assessing how different weather
events have affected various activities. Elements
covered are: temperature (maximum and minimum);
rainfall; wind (average and maximum gust); sunshine;
significant weather - days when thunderstorms, hail,
fog, snow or gales were reported.

Downtime Summaries
A summary of the previous months (hourly, 0700-1700)
weather conditions, with comparisons against long-term
