Meaning
The weather is unpredictable and can change anytime.
Cultural Background
Weather is the most common 'icebreaker' in Finnish culture. Because Finns value silence, commenting on the unpredictability of the weather is a way to acknowledge another person's presence without being intrusive. In the north, the phrase takes on a more serious tone. Weather can change from safe to life-threatening in minutes on the fells (tunturit). Here, the phrase is a reminder of the power of nature. Sailing is a huge part of Finnish summer. The phrase is used by sailors to explain why they are constantly checking barometers and multiple weather apps. In the city, the phrase is often used ironically when the 'sea effect' causes snow to fall in one neighborhood while the sun shines in another.
Add 'koskaan'
Adding 'koskaan' (never) makes you sound much more like a native speaker. 'Säästä ei koskaan tiedä' is the gold standard.
Watch the Case
Don't forget the -stä ending. Saying 'Sää ei tiedä' is a very common beginner mistake that sounds funny to Finns.
