Met Office's short-range forecasting accuracy is one of its four key performance targets which is regularly monitored by the Met Office Board on behalf of the Minister. The targets are agreed annually and are laid in Parliament. Met Office report against their performance in their annual report which is also laid before Parliament.
As a World Meteorological Organization (WMO) designated centre for seasonal/long-range forecasts, Met Office is required to carry out assessments of its forecasting accuracy using procedures laid down by WMO. The most recent assessment was carried out in September 2009.
