I like this definition from Wikipedia, talking of silly season:
The silly season is the period lasting for a few summer months typified by the emergence of frivolous news stories in the media. This term was known by the end of the 19th century and listed in the second edition of Brewer's Dictionary of Phrase and Fable and remains in use at the start of the 21st century. The fifteenth edition of Brewer's expands on the second, defining the silly season as "the part of the year when Parliament and the Law Courts are not sitting (about August and September)". In the United States the period is referred to prosaically as the slow news season. In Australia, New Zealand, and South Africa, the silly season has come to refer to the Christmas/New Year festive period on account of the higher than usual number of social engagements where the consumption of alcohol is typical, which are in the Southern Hemisphere summer.
Instead now the noise of vote seeking is over and I am ready to be disappointed once again by our leaders created during the District of Columbia Silly Season. So I look at a lovely pink Hibiscus, suitable for our silly season, that time of year when snow falls Up North and we get to hear about if from lots of people happy to have escaped the noose of the snow shovel for a winter. Silly season down here is when the flowers bloom not when snowflakes fall. Not bad even if we have to put up with slow drivers, loud talkers and silly cyclists clogging our lives for a few weeks. They'll be gone soon when the weather gets really nice.
