Very useful for sailing, but also biking, hiking, any kind of outdoor activity. Turns out a certain temperature with 5 mph wind feels very different from the same temperature with 20 mph wind.

Most regular places that show weather present the work as "their" forecast, but they're typically repackaging weather model information. No pretense here.
