October’s blocking high pressure kept Western Europe clouded and rainy, reducing solar irradiance, while Eastern Europe experienced above-average irradiance, boosting solar output across the region.

Our 2024 validation study reveals Solcast’s performance across 135 sites, delivering the reliable metrics that enable better decision-making in solar energy and grid management.

October set irradiance records in the U.S., with a stable high-pressure system over the East and Central regions driving clear skies and elevated solar generation, while hurricane disruptions impacted Florida's solar output.

Latest La Niña forecasts suggest sunnier skies for parts of North and South America, with reduced precipitation that could enhance solar generation this winter.

Contrasting solar conditions emerged in September, as low-pressure systems brought cloud cover to Western Europe, while Northern regions benefited from sunnier, high-pressure conditions.

Hurricane Milton caused localized disruptions to solar energy in the southeast but solar production across the rest of the US remained strong, with many regions experiencing above-average irradiance.

Some regions of South America saw record solar generation due to clear skies, while areas near the Amazon experienced up to 20% drop in irradiance due to wildfires. Learn more about its impacts on the latest analysis using the Solcast API.

Understand how cloud cover and cloud opacity impact surface irradiance. Learn which metric is more applicable for solar energy applications.

August 2024 saw record-breaking solar irradiance in the Southern US due to sustained clear skies, while the Northeast struggled with cloud cover and rainfall, which significantly impacted solar production. Learn more about the contrasting weather conditions across North America.

Storm Boris brought severe flooding with record-breaking rainfall across Central Europe, while the UK and Alpine regions saw their first snowfalls of the season.
