South Bend IN wind rose

The following table was obtained from the National Climatic Data Center



Numbers in the body of the table are the percentage of time that winds are observed
at speeds indicated in the column headings from the direction shown in the leftmost column.

VAR = winds from variable direction
CLM = calm conditions (no wind)

The total percentage of time winds are observed from a given direction regardless of speed
are shown in the MEAN PERCENT column (calm excluded).

The total percentage of time winds are observed at a given wind speed range regardless
of direction are shown in the ALL row.

Example:  Winds from the south-southwest direction at speeds of 11 to 16 knots are expected
to occur 3.2 percent of the time during the year.

Multiply wind speeds by 1.15 to convert to miles per hour.
