Seasonality Core 2.0 is a Mac app any weather aficionado should have. That's because it's probably the most complete and detailed weather software I've ever seen on the Mac.

I'm a big fan of good weather-reporting software for years but never thought I'd find nirvana so easily. No weather program I've ever tried, for Windows, Linux or OS X, comes within a light year of Seasonality.
