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 average daily wind speed in March has been around 21 km/h, thatâs the equivalent to about 13 mph, or 11 knots. In recent years the maximum sustained wind speed has reached 109 km/h, thatâs the equivalent of around 68 mph, or 59 knots.
