Climate Forecasting at the Leading Edge of Science
The World Climate Service Offers Two Industry Leading Products:
Forecasts and climate analysis tools providing guidance for 1-6 months into the future. The seasonal WCS subscription provides access to a comprehensive monthly report as well as unique and interactive website tools such as model progression visualization and an index analog database.

Forecasts and analysis tools focused on a 2-6 week forecast lead time. Subseasonal forecasting is an emerging field that has long been regarded as even more challenging than seasonal forecasting, and demand for actionable subseasonal climate forecast guidance is growing rapidly.

We endeavor to provide the world’s most reliable, valuable, scientifically advanced climate forecasts and long-range weather intelligence for commodity trading desks and other entities. We strive for excellence in all aspects of our work.
The World Climate Service is unreservedly committed to ethical business practices and a transparent scientific approach to long-range seasonal climate forecasting.
The emerging field of seasonal and subseasonal climate forecasting demands ongoing research and development while refining existing techniques. The World Climate Service is known for an agile development process and rapid product roll-out.
- The World Climate Service avoids over-reliance on a single forecast tool or method. The complexity of the long-range forecast problem demands a broad suite of predictors and an intelligent system to extract predictability.
Probability and Confidence
- The World Climate Service provides and promotes information about forecast confidence and uncertainty. By embracing a probabilistic approach, WCS clients take advantage of high-probability “forecasts of opportunity”.
- The World Climate Service empowers user decision systems by providing automated data feeds. Quantitative forecasts of industry-specific variables allow clients to make weather-sensitive decisions with precision and confidence.
The WCS Team
We offer nearly 60 years of experience in seasonal forecasting

News and Analysis from the World Climate Serivce
The Arctic Oscillation was an important player in widespread Northern Hemisphere winter warmth, but the hemispheric temperature-AO relationship is not simple
One of the most striking features of global climate variability in 2019 was the development of a strongly positive phase of the Indian Ocean Dipole (IOD). The IOD is a mode of coupled ocean-atmosphere variability in the Indian Ocean, and it has strong impacts on climate anomalies in the surrounding areas and farther afield. See[…]
On November 18, the World Climate Service issued its seasonal forecast and discussion for winter (December-February) 2019-2020 in the U.S. and Europe. WCS seasonal outlooks include an overview of expected climate anomalies, key drivers, and risk factors for the upcoming three-month season, and our forecast document contains detailed discussion of available predictors, including dynamical model[…]
In an October 31 blog post, distinguished meteorologist Cliff Mass of the University of Washington commented on the degree of usefulness of long range forecasts, with the title, “Extended Forecasts Are Not Reliable“. Dr. Mass highlights the lack of deterministic skill of temperature and precipitation forecasts in the dynamical forecast models beyond two weeks and[…]
One of the core products that the World Climate Service delivers to customers is a once-a-month seasonal forecast report focused on expected climate conditions in the next three months in Europe and North America. This includes a European summer forecast. The report includes a comprehensive discussion of factors that are likely to influence the seasonal[…]
The World Climate Service seasonal discussion and forecast for autumn was issued a few days ago, and as always the North Atlantic MSLP pattern featured heavily as an important consideration in the forecast, especially for Europe. Guidance from the leading seasonal dynamical models, provided by the Copernicus Climate Change Service, typically provides a significant component[…]
In late July, an episode of extreme heat developed over western Europe for the second time in summer 2019, and all-time high temperature records were broken in several countries. Among these, the UK set a new high temperature record of 38.7°C (102°F) in Cambridge on July 25. As seen in the map below, temperatures that[…]
US Bureau of Reclamation Press Release On March 7, 2019, the U.S. Bureau of Reclamation (USBR) announced the winners of their Subseasonal Climate Forecast Rodeo, which took place between April 2017 and April 2018. Prescient Weather participated in the contest and performed very well, ranking first for all categories combined and second in all but[…]
Introduction to Seasonal and Subseasonal Probabilistic Forecasts The probabilistic climate forecast is emerging as a an important tool for companies to gain value from long-range forecasts. The World Climate Service seasonal and subseasonal (S2S) weather forecasts emphasize probabilistic information, which is less intuitive but more powerful than the traditional style of deterministic short-term weather forecasts. […]
The World Climate Service uses a special technique called “calibration” to ensure the forecasts of probabilities of weather events are properly estimated. It’s a fairly complex technique that requires processing a significant amount of retrospective data from dynamical models such as the CFSv2 and the ECMWF. The subseasonal and seasonal dynamical model calibration methodology used[…]
