Spire Global Inc. (NYSE: SPIR) announced an expanded energy trading intelligence service that provides weather forecasts spanning from intraday to 45 days through its Cirrus platform, according to a company press release.

The satellite data provider's new offering includes four forecast products: High-Resolution Forecast covering 0-7 days with twice-daily 3 km forecasts across the U.S., Europe, and Southeast Asia; Optimized Point Forecasts for 0-15 days with hourly updates at over 10,500 global sites; Power Generation Forecasts for 0-15 days that convert weather data into wind and solar generation predictions; and Spire AI-S2S for 1-45 days using a 200-member generative AI ensemble.

The company stated its AI-S2S model outperformed the European Centre for Medium-Range Weather Forecasts sub-seasonal forecast by 14.2% on surface temperatures at 3-6 weeks during validation testing conducted from January 1 to February 15, 2026. The model operates independently from public forecast systems and uses satellite-derived data.

"Weather is now the single biggest unpriced variable in energy markets — and the traders who forecast it better win," said Shawn Mechelke, General Manager, Weather, Climate and Aviation at Spire.

The Cirrus platform consolidates all forecast products with public benchmark models in a single interface designed for energy trading desks. The products are also available via API for integration with existing trading infrastructure.

Spire operates a satellite constellation that provides global weather intelligence, ship and plane movements data, and spoofing detection services. The company has offices in the U.S., Canada, UK, Luxembourg and Germany.
