Autumn 2025 saw contrasting solar performance in Australia: East Coast underperformed while the West and South saw gains. Learn how high pressure shaped irradiance patterns.

East Coast solar underperformed in May due to storms, while West and Midwest saw stable conditions. Learn what drove this split in solar conditions.

Recent aerosol events from Saharan dust and Canadian wildfires cut solar irradiance by 5-7% across the Mediterranean in May. Learn more about the progression of these dual aerosol events and their impact on solar generation.

Dublin has recorded more sunshine than Madrid this May, with Ireland seeing a +30% irradiance anomaly. Northern Europe’s solar performance reversed the usual pattern as stormy weather hit Spain and Portugal.

Europe’s 2024 climate report highlights an east-west solar split, aligning with Solcast’s anomaly findings from earlier this year.

Irradiance in surged across the Southern US and Midwest, while storm systems clouded the skies over the Western US and Canada.

ECMWF has released its first operational AI weather model with solar forecasting capabilities—AIFS V1. The Solcast Data Science team benchmarked its performance against IFS and GFS, showing promising accuracy but a conservative irradiance bias.

Early 2025 saw sunny skies across East Asia, with solar gains up to 30%, while maritime Southeast Asia faced deficits from heavy cloud cover.
