Heliospheric Weather Expert Service Centre - Solar Wind Forecast Speed Comparison

The solar wind forecast speed comparison at Earth provides an overview of the different solar wind forecasts products that are available from the H-ESC. The data used for the comparison is captured once an hour. For the most recent forecasts please follow the links at the bottom of the page to individual products.
