Intempestive is an adjective that means untimely or out of season.

The Latin word tempestivus (tem PESS teev oose) means timely. With the addition of the prefix I-N, meaning ‘not,’ we get a word that means ‘untimely.’ Here’s an example of intempestive in use:

I normally enjoy a good Christmas parade, but last week’s was a little intempestive. Maybe having it take place in early June wasn’t such a good idea.
