The solar wind speed at Earth normally lies around 300km/sec but increases when a coronal hole high speed stream (CH HSS) or coronal mass ejection (CME) arrives. During a coronal mass ejection impact, the solar wind speed can jump suddenly to 500, or even more than 1000km/sec.
Winds on Jupiter and Uranus pale in comparison to those of the other gas giants, however. The Voyager 2 spacecraft detected easterly winds on Saturn of 1,800 km/h (1,120 mph), but the record for windiest atmosphere in the solar system belongs to Neptune at a whopping 2,100 km/h (1,300 mph).
