Every 11 years. The entire solar magnetic cycle takes about 22 years; twice in this cycle there is a sunspot maximum.
Yes, the shape of a sunspot cycle can be described as somewhat wavy. Sunspot activity follows an approximately 11-year cycle with peaks and valleys in sunspot numbers over time, reflecting the Sun's magnetic activity. This cycle is not perfectly regular due to various factors influencing the Sun's behavior.
The sunspot cycle is an approximately 11-year periodic variation in sunspot number on the Sun. It is characterized by a rise in sunspot activity leading to a peak, followed by a decline in activity to a minimum, and then the cycle repeats. Sunspots are dark regions on the Sun's surface caused by its magnetic field, and the cycle is linked to changes in solar activity and space weather.
It is often referred t as The Sunspot Cycle - period of about 11 years.
The last sunspot cycle may have ended in December 2008 (Cycle 23). However, due to lack of sunspot activity, scientist are unsure whether cycle 23 has ended yet, or whether cycle 24 is just starting. A rough guess would place the timing around December 2009 but as with everything, nothing is certain, certainly not the sunspot cycle. (The 11 year cycle is a mean value and cannot be taken as precise). Given the approximate 11-year cycle, and assuming that cycle 24 started in January 2009, then the PEAK of sunspot activity should occur about 5 1/2 years from then, around summer 2014.

We do not yet have a good understanding of the way that sunspot activity changes. We've only been keeping track of sunspots since the early 1600s. In general, sunspot activity increases and decreases in a cycle that is approximately 11 years long. But the cycle isn't particularly stable; for example, the previous cycle, Solar Cycle 23, lasted for closer to 13 years and the current Solar Cycle 24 has been fairly low in activity. This may have long-term significance in our weather here on Earth; twice in the last 4 centuries, we've seen extended periods of very low sunspot activity, and both periods have been associated with unusually cold weather. Some scientists fear that the current sunspot deficit may be a prelude to a new period of cooler-than-normal weather.
The average sunspot cycle is approximately 11 years, with periods of high sunspot activity followed by lower activity levels. This cycle is known as the solar cycle or the sunspot cycle.

The sunspot cycle typically repeats approximately every 11 years, though the length can vary from about 9 to 14 years. This cycle is characterized by the waxing and waning of sunspot activity on the Sun's surface.

Sunspot cycles are caused by the differential rotation of the Sun. This rotation causes the Sun's magnetic field lines to become twisted and tangled, leading to the formation of sunspots. The solar cycle lasts approximately 11 years, with sunspot activity peaking and then declining.
