I refer to the NOAA Space Weather Prediction Center "Solar Cycle Progression" report :
http://www.swpc.noaa.gov/SolarCycle/
"...the panel has agreed that solar minimum occurred in December, 2008... Given the predicted date of solar minimum and the predicted maximum intensity, solar maximum is now expected to occur in May, 2013. Note, this is a consensus opinion, not a unanimous decision. A supermajority of the panel did agree to this prediction."
The maximum Sunspot Number Monthly Value for Cycle 24 MAY have already occurred in October 2011, with a value of about 95.
