What forecast tools does World Climate Service offer?

World Climate Service offers six long-range forecast tools for energy trading desks: Medium-Range (1-15 day forecasts), Subseasonal (2-6 week outlooks), Seasonal (1-9 month outlooks), U.S. Trading Markets (HDD and CDD for all U.S. power ISOs), UK Gas Demand (CWV across 13 LDZs), and a Point-in-Time Weather Forecast API for systematic strategies.

Which markets do World Climate Service tools cover?

Coverage spans U.S. power ISOs (PJM, MISO, NYISO, CAISO, ERCOT, ISO-NE, SPP), U.S. natural gas at Henry Hub and regional hubs, UK NBP gas with all 13 LDZs, and European gas hubs including TTF and NCG. Climate driver tracking includes ENSO, NAO, AO, PNA, MJO, PDO, and AMO across all horizons.

What is a point-in-time weather forecast API?

A point-in-time weather forecast API delivers historical forecasts exactly as they were issued, with no look-ahead bias, plus real-time delivery on the same data structure. This allows quantitative analysts to backtest weather-driven strategies on realistic data, train models on operational forecast errors, and deploy the same API in production.

How do energy traders use long-range weather forecasts?

Day-ahead traders use medium-range temperature forecasts to model HDD and CDD across ISOs. Term traders use 2-6 week subseasonal outlooks to size forward positions before the curve reprices. Seasonal forecasts guide winter and summer hedging decisions, and a point-in-time API supports systematic quantitative strategies on weather data.

What is the difference between medium-range, subseasonal, and seasonal forecasts?

Medium-range forecasts cover 1-15 days using ensemble models like ECMWF and GEFS. Subseasonal forecasts cover 2-6 weeks and rely on teleconnections such as the MJO, NAO, and PNA. Seasonal forecasts cover 1-9 months and use ocean drivers like ENSO, PDO, and AMO. Each horizon serves a different decision: day-ahead dispatch, term hedging, and long-term positioning.
