-> ''The last rose of summer, is blooming on the lawn\\
All her lovely companions are faded and gone...''
-->--'''Thomas Moore''', "The Last Rose of Summer"

In any setting where exists a standard [[SeasonalBaggage four season]] climate, there will always be an episode or chapter where it is unseasonably warm and beautiful. This will always occur at the beginning or end of summer ([[SmallReferencePools depending on whether summers in the area]] are known for [[HeatWave being oppressively hot and humid]], or [[SummerCampy blessed and carefree]], respectively.)

[[http://en.wikipedia.org/wiki/Indian_summer Indian summer]] weather is always important to the plot, as it signifies the beginning of the last chapter in the characters' relationship -- a Romance, a Road Trip, etc. The characters are able to enjoy some carefree time together right before [[RuleOfDrama things start to go south]].

If it is a ComingOfAgeStory, the last time the characters get together to have fun before going their separate ways will always be an unseasonably warm and pleasant day. Some huge relationship battle will invariably occur and separate the [[TrueCompanions tight-knit group of characters]] by nightfall, only to have them reunite (possibly years later) in more depressing circumstances, usually [[ItAlwaysRainsAtFunerals in the rain]].

Compare BittersweetEnding. Inverse of ItsAlwaysSpring. Closely related to FirstSnow.

Contrast DreamingOfAWhiteChristmas, HeatWave.

Not to be confused with the [[UsefulNotes/{{India}} weather in India]], although the trope fully applies to works set in South Asia on unseasonably ''cool'' days, or with a certain anime of the same name (alternately known as Koharu Biyori).
