If you can’t talk about anything else you can always talk about the weather, along with other common small-talk topics such as Sunday’s game or supermarket sales.

But the reason why everybody can talk about the weather it is because it is something we all share, one way or the other, so to speak.

To some people a weather forecast is mostly about whether or not to wear warm clothes the next few days, to others it is far more serious business. Such as pilots, sailors or people participating in outdoor sports or concert events.

Keynote speakers on the weather typically look at different types and aspects of weather and about various weather conditions.
