I've been v lucky as I've only lost 1 day this year due to bad weather. That was last week when it bounced down all day and I had to rearrange a conny clean.
I have a good amount of inside build cleans that I pile up ready for bad weather days. This way I'm still earning no matter what the weather.
I'm off on my hols tonight though, 2 weeks in Greece so I'll not be worrying about the weather or work for a while! Hope the sun comes out for you fellas though!
