Which phrase would most likely be used when describing an absence of extreme weather?

Describing an absence of extreme weather typically implies a mild and pleasant condition. The phrase "It's sunny" suggests clear skies and favorable weather, indicating stability and comfort without the harshness that extreme weather conditions bring. On the other hand, the phrases mentioning wind, rain, or snow all imply significant weather activities that could be considered more extreme and indicative of less stable atmospheric conditions. Therefore, "It's sunny" is the most fitting choice to convey a sense of calm and absence of severe weather.
