No cast of cycle 25, where we compared cycle 25 to various historical data: the previous cycle 24 (dashed line), cycle 23 (the odd numbered previous cycle in dotted line) and two averages of the past record, a mean of the previous 24 cycles (cyan dash-dotted), and of the last 5 (pink dash-dotted). As we can see, none of these no cast or historical data provide an accurate prediction of the ongoing cycle 25.
