One of the best tools to forecast HF (high-frequency) propagation is the online map (chart) shown below.
It is a graphical representation of MUF within a 3000-kilometer range, allowing amateur radio station operators to estimate the best frequencies and paths for effective communication.

See HF propagation today and an index of terms for HF Radio Propagarion.
The project "Understanding HF Propagation" provides a detailed overview and tutorials on HF propagation.
