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.
Over the course of the year typical wind speeds vary from 0 mph to 16 mph (calm to moderate breeze), rarely exceeding 23 mph (fresh breeze). The highest average wind speed of 10 mph (gentle breeze) occurs around March 3, at which time the average daily maximum wind speed is 16 mph (moderate breeze).
