Long range weather forecast
This long range forecast for the UK is updated once a month. Using the latest long range data from the NCEP and then run through custom software here at Netweather it is on the cutting edge of technology for long range weather forecasting. It is important to bear in mind that forecasting at this range is still in its infancy so can effectively be considered experimental.
Updated 10th August 2016
The start of Autumn is currently forecast to see slightly lower than average pressure over, and to the north of the British Isles, so a quite mobile month is expected. With the mobile pattern, a slightly wetter than average month is expected, although some parts very near to the average. A pretty typical month is expected temperature wise, with not too much of a deviation from the seasonal norm overall.
September Air Pressure
Into October, and the Azores high is currently forecast to ridge a little further north than usual, so with higher than average air pressure anomalies across the southwest of the British Isles. It's a fairly weak anomaly though, leading to average rainfall totals in the southwest, elsewhere a slightly wetter than average month is expected. Much like September, temperatures are forecast to be near to the norm for the time of the year.
October Air Pressure
Very low confidence at this range, with the air pressure forecast not showing any strong signals. But currently the expectation for November is for the majority to see a milder than average month, coupled with slightly below average rain amounts.
Next long range update will be issued early September, with a first glance ahead to Winter..

Useful Weather Forecasts For You
The long range weather forecast displayed on this page is based on data from the Climate Forecast System from the NCEP (USA), run out to 9 months in advance and are updated once a month. The raw data is sent daily to Netweather, our systems then average and further process that data to produce the forecast you see below. The average figures you see on the forecast are not the standard 1971 to 2000 figures you may often see, instead they are rolling averages, currently from the period 1981-2010.
