Seasonality Core is the complete weather center for your Mac. View weather at any of the 34,000 built-in locations in more than 200 countries, or add your own custom weather location to view even more precise data. Seasonality gives you an accurate 7 day forecast, graphs of past weather conditions, a custom satellite/radar image, and much more.

Seasonality Core's graphs are excellent at showing how weather conditions are changing over days, months, or even years. Seasonality Core will automatically collect and store weather data indefinitely.

The custom satellite/radar image gives users the option to adjust opacity of both overlays, show the latest North American surface analysis, and view the global wind flow with Particle Mode.
