Hi

I am a farmer and seasonality is the essence of our business.

You didn't mention if this is a cafe especially for bikers on the road or vice versa. A place to fix bikes and have a cafe while you wait?

So the answers may fit one situation and not the other.

1 Close for the off-season. find for yourself and wife another jobs and reopen again in the good season. hopefully by next year you will have a good solution so you don't have to do this again- or maybe do this again

2. Imagine you were not around what solutions exist for your customers.. and see if you can work this into your off-season activity

3.Do things different and do diffrent things - example winter ice-cream, or summer soup...
with this I mean ideas that work around the seasonality issue. Here people only eat watermelon in summer. But we produced mini watermelon and called it winter watermelon. It works..

4. If you repair bikes - hire a van and start going around town advertising when you will be where at what time. Fix-em bike

5. If the cafe is your core business hire a van and go around town selling cafe stuff

good luck
