The NOAA/NASA Solar Cycle Prediction Panel is puzzled. They don’t know if we are reaching solar maximum or whether another little peak could be on its way which would shift solar maximum for SC24 to 2014 from 2013.
And should we compare SC24 with SC14 or should it be SC5?
But SC24 will still show the lowest sunspot activity for 100 years. I note that not only SC14 but even SC5 had a double peak – so my expectation remains that this Landscheidt Minimum may be comparable to the Dalton Minimum – though not perhaps to the Maunder Minimum.

This Sciencecast video is a good summary of what we don’t know:
Landscheidt’s prediction is that this Minimum will last till 2060 so we can expect low sunspot activity for the next 4 sunspot cycles (till SC28).
Landscheidt’s predicted solar minima
The Sc24 – SC5 comparison looks like a repeating pattern but it would be wrong to assume that the Sun cares about this and it will surely continue to keep us perplexed as it does its own thing.
SC24 compared to SC5
The Big Picture is persuasive – even if we don’t really know what the sun is upto and even less about how the Earth dances to the Sun’s music.
