Empowering Decisions
Beyond The Range of Traditional
Weather Forecasts


The World Climate Service offers two commercial products
  • Seasonal Forecasts

    Forecasts and 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.

  • Sub-Seasonal Forecasts

    Forecasts and analysis tools designed for a 2-6 week lead time. Sub-seasonal forecasting is an emerging field that has long been regarded as even more challenging than seasonal forecasting, and demand for actionable sub-seasonal guidance is growing rapidly.

Core Commitments


We aim to provide the world’s most reliable and valuable long-range weather intelligence for every public and private enterprise. 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 forecasting.


The emerging field of long-range weather and climate forecasting demands ongoing development and refinement of techniques. The World Climate Service is known for an agile development process and rapid product roll-out.

Competitive Advantages

Comprehensive Approach
  • 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”.
Data-Rich Services
  • 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.
