August Propagation
The period from late August through early September is a difficult time of year for which to make accurate band predictions because conditions can change drastically from day to day. On many days, typical summertime conditions will continue much as they were during June and July. On the other days, conditions may sound typically fall-like, with somewhat higher daytime usable frequencies and somewhat lower nighttime usable frequencies. When you add equinoctial conditions that can begin as early as late August, we often experience optimum openings between the northern and southern hemispheres on the one hand, but periods of active to stormy conditions on the other.
Despite being at the start of Solar Cycle 25 with low solar activity, good DX conditions should be possible on several bands during the daylight hours, specifically 15, 17, and 20 meters. Expect signals on the 17-and 20-meter bands to
