Selling sponsor spots for your weather forecasts is a great way to raise additional revenue.


The maximum length of a sponsor is 175 characters which is approximately 20-25 words.

{info} In order to keep the forecast within 30 seconds, as the sponsor gets longer, the weather forecast will get shorter. Meaning, less details are given or less weather periods are provided in order to accommodate the longer sponsor.


Here are some examples to get you started.

If you don't currently have a sponsor, you could use something like the following:

  • listeners like you
