Are Spring temperatures broken? (and is there a mod to fix them?)

Whatever method is used to address this, just wanted to point out that no matter how unseasonably cold or warm it seems the weather forecast in TS3 is nonsense. I mean, it is reported to be correct occasionally in a random kind of way but most often it's way off. We're not sure if the developers felt that TS3 weather is too difficult/impossible to predict beyond the current sim day or if the whole thing was some sort of joke to them (or both).

That does seem a bit chilly for "paradise," though.
