Default The next crap; many sunspots and no conditions !

I don't know much about sunspot counting, so I thought it might be
useful to Google for how it's done:
http://spaceweather.com/glossary/sunspotnumber.html
Looks like we have the "Boulder Sunspot Number" and the "International
Sunspot Number". Boulder is about 25% higher than International. The
ARRL uses the "Wolf number" from Zurich:

This month's count. Note the wide variation:

Average? Ok, that's explained in the FAQ:

From the SpaceWeather page, counting your own might be problematic:
As a rule of thumb, if you divide either of the official
sunspot numbers by 15, you'll get the approximate number
of individual sunspots visible on the solar disk if you
look at the Sun by projecting its image on a paper plate
with a small telescope.

Hmmm... Maybe I didn't want to know more about sunspots.
