Sunspots AR2671 and AR2672 have 'beta-gamma' magnetic fields that harbor energy for M-class solar flares. However, they have been mosty quiet for days, so NOAA forecasters think the chance of a flare is low. Credit: SDO/HMI

As you can see by the 2017 stretch of 56 days without sunspots, it hasn't been anything like this since 2009. So, likely we are moving into a cycle of less sunspots for now. But, if we compare that to 2013 to 2015 there were no days without sunspots in 2013 and 2015 and only 1 day without any sunspots in 2014.
