Weather report

Any kind of weather-dependent cleaning is always a double-edged sword. On one hand, if the weather is unfavorable enough, you're off the hook. On the other hand, such weather often makes future cleaning attempts more difficult, whether it's having to deal with a bigger mess or being scolded by friends and family for not being proactive enough.

Modern thinking would suggest that you just pay someone else to do your cleaning, regardless of the weather.
