Global HF propagation conditions refer to the overall state of high frequency radio propagation across the entire planet. It is used to make broad predictions about the potential for wolrdwide communications.

Solar activity, and space weather influence these conditions.

On the other hand, Regional HF propagation conditions, refer to the state of radio frequency propagation within a specific geographic region. These conditions can vary widely depending on local factors such as topography, weather conditions. Regional HF propagation conditions are often more important to individual operators, as they can have a significant impact on the success of communications within a specific area.

In general, global HF propagation conditions provide a broad overview of the state of the HF bands, while regional HF propagation conditions provide a more detailed picture of the conditions that individual operators are likely to experience. Both types of conditions are important for amateur radio operators and shortwave listeners, as they help to guide frequency selection and other operational decisions.

The project "Understanding HF Propagation," focuses on skywave propagation,
shows near-real-time indices and explains what the terms mean.
