One question I’ve always wondered about flying from KBJC is: Are summer afternoons really the windiest time to fly?
Thanks to some historical METAR data, I’ve been able to answer that question.
In short, no. After looking at the past three years of METAR data between 8AM and 8PM (local) it appears the summer winds are relatively more mild than the spring winds. In particular, March.
March is unique in its wind pattern as it builds early and maintains its strength throughout the the day. This is in contrast to more typical patterns of light winds in the morning and then building throughout the day.
In fact, to become a proficient flyer in the prevailing winds we see at KBJC, it looks like there is no better time than March to get out and fly.
