Sunspot 'cycles' are at approximately 11-year intervals.

Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.

The sunspot cycle is about 11 years long. This can vary somewhat; the current cycle has had an extended minimum with very few sunspots for about 3 years, and even now the sunspot numbers are very low for this point in the cycle.
when sunspots fade away, they usually leave behind a weak magnetic imprint of opposite polarity to that of the sun's global field at the cycles start. by Amanda Reyes

Solar cycles average about 11 years each. The eleven year cycle is measured by changes in the Sun's output, ejection of solar materials, sunspots, and auroras on Earth. Sometimes the cycle is referred to as a 22-year one since the sunspot activity reverses solar hemispheres (changes polarity) in alternating cycles.
