I don't bother worrying about what's allegedly a "slow season" and what isn't because no matter the time of year, you can find people arguing that it's slow. Even when it is slow, it's totally possible for you to have a good month/season.
If you base it on the alleged "slow" periods, the beginning of the year is slow because everyone has to pay their taxes. After taxes are done, summer hits and it's slow because everyone is on vacations with their families. Then fall comes and it's slow because ???? it just is, and then the holidays come and it's slow because everyone is spending money on gifts for their families. Or whatever.
It's almost like you can hit a slow period at any time...
Don't worry about it.
Pay attention to your own hustle. If you've noticed a dip in income that lasts for more than a few weeks, it might be a sign that maybe you should switch up your show a little because what you're doing isn't working. If you have a slow day or week, it's probably just bad luck and will pick up soon.
That said, there are definitely slow moments that have actual causes, but I've found that they last a day or a week, not a month or a season. For example, I tried to cam on Super Bowl Sunday. People are not watching cams on Super Bowl Sunday, they're watching the Super Bowl.
