The 2020 CQ World Wide CW DX Contest <www.cqww.com> will start at 0000 UTC, Saturday, November 28th and continue until 2400 UTC, Sunday, November 29th. Expect fair conditions for both contest days. With quiet conditions, the contest weekend should provide reasonable propagation consistent with a low sunspot count.
The best tool available to predict HF propagation conditions in advance is the 27-day recurrence tendencies of geomagnetic, solar, and ionospheric conditions. It is not an absolute method, but it does give a good indication of what is expected. Predictions for one 27-day rotational period are far more accurate than
