With The Sims 4 Island Living, there will be also a new weather type, SimGuruMorgan explained more about this on Twitter.
To get this weather type, you do need to have The Sims 4 Seasons installed as well.
I know a lot of you have been asking about weather. Designer Geoff put a lot of thought into the unique weather patterns of Sulani (with Seasons installed), and I thought you might all enjoy the love and attention that went into it.

SimGuruMorgan: I know a lot of you have been asking about weather. Designer Geoff put a lot of thought into the unique weather patterns of Sulani (with Seasons installed), and I thought you might all enjoy the love and attention that went into it.
Island Living has a new weather event unique to Sulani: the Tropical Monsoon, a warm thunderstorm that occurs at random from late summer through late fall. Monsoons are intense but short-lived and visualized by heavy rain, dark clouds, high winds and frequent thunder/lightning.
Less obvious are the new tropical versions of existing weather types (cloudy, partly-cloudy, windy, rainy and clear) that have warmer temperatures earlier in the day (by mid-morning) and last longer before cooling off overnight. During winter, days are cool.
Finally, there was some special work done to incorporate big, “mountainous” clouds that appear in the skybox on the horizon, but still manifest “clear” days functionally to support sunbathing and other sunny weather gameplay (i.e. vampire exposure).
SimGuruGeorge made a new gif to show off this weather event. And it looks threatening!
