Long range weather forecasts

Our extended-range forecasts provide an overview of potential weather conditions up to 46 days ahead, focussing mainly on average conditions week by week and how different they are from a long-term model-based climatology. For example, charts show if the average conditions over a week are predicted to be colder or long range weather forecasts than normal for that time of year. The extended-range forecasts are produced daily and have a horizontal resolution of around 36 km. Find out more about how the extended-range forecast is produced.

These include day outlooks, monthly outlooks, and seasonal outlooks. Unlike regular "zone forecasts" issued by a local National Weather Service office, the climatological outlooks provide probability forecasts for both temperature and precipitation, divided into tercile groups: below normal, near normal, and above normal.

Our long-range seasonal forecasts provide information about atmospheric and oceanic conditions up to seven months into the future. They are produced every month with a member ensemble at a horizontal resolution of around 36 km. Annual forecasts are produced with the same system every three months and extend 13 months into the future. Long-range charts include differences or anomalies from a long-term model-based climatology and probabilities of above normal, normal or below normal conditions. Find out more about how our long-range forecasts are produced. Like the medium- and extended-range forecasts, our long-range forecasts are produced using the ECMWF Integrated Forecasting System IFS which uses an Earth system model to represent interactions between the atmosphere, ocean, land and other Earth-system components. Long-term predictions rely on aspects of Earth system variability which have long timescales months to years and which are, to a certain extent, predictable.
