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.
The highest average wind speed of 5 mph (light breeze) occurs around January 31, at which time the average daily maximum wind speed is 11 mph (gentle breeze). The lowest average wind speed of 4 mph (light breeze) occurs around January 8, at which time the average daily maximum wind speed is 10 mph (gentle breeze).
