Long range forecast

Monday 17 Aug - Wednesday 26 Aug

The beginning of the period should see settled conditions persisting with cloudy and humid conditions interspersed with sunny spells. Some light rain may spread north-westwards at times towards the middle of August. Southern and southeastern areas may see further periods of hot weather and thunderstorms at times throughout the period. Elsewhere it is likely to remain warm or very warm though cooler than last week. Fog patches are possible overnight for many which should readily clear during the mornings. Northwestern areas may see more changeable conditions developing towards the end of the period with a mixture of windier and wetter days mingled with drier days. Eastern and northeastern areas are likely to remain more settled throughout.

Thursday 27 Aug - Thursday 10 Sep

Although confidence is low for this period, conditions will likely become more changeable with periods of rain and breezier days at times at the end of August and into September, with temperatures returning to around average for the time of year. However, eastern areas will see the best of more settled weather with lighter winds and drier days. There is a possibility that some southern regions will turn very warm with thunderstorms at times.

Why isn't there more detail in the long range forecast?


Ever wondered why our forecasts for 5 days and beyond are written on the scale of the UK as a whole? When looking at forecasts beyond five days into the future the chaotic nature of the atmosphere starts to come into play - small events currently over the Atlantic can have potentially significant impacts on our weather in the UK in several days' time. Therefore whilst we can still forecast the general feel of the weather to a relatively high level of accuracy using our ensemble models, it becomes harder to offer local detail to as high a level of accuracy as our shorter range forecasts. For this reason our text forecasts for 5 days and beyond are written on the scale of the UK as a whole.

Our long range forecast (which is updated on a daily basis) provides an indication of how the weather might change, or be different from normal, (i.e. warmer, colder, wetter, drier) across the whole UK. Met Office meteorologists consider output from a range of weather models when writing these forecasts. These models include those from the Met Office as well as models from other global forecasting centres such as the European Centre for Medium Range Weather Forecasts ( ECMWF).
