The darkened computer terminal in the clubhouse was the only bad sign of the day. A few golfers had seized the opportunity presented by unexpectedly warm temperatures to squeeze in a bonus round in mid-November. The course was a bit scruffy, showing signs of hibernation, but still remained in good enough shape to play.
This round had been an ideal way to cap the playing season, but finding the handicap computer dormant was confusing. If the weather had been good enough to play, the players wondered, how could the computer be off?
In contacting the Handicap Chairperson, the players learned that their games may have been active that day, but for handicap purposes they might as well have stayed home. Why? During winter months in some states, scores are not posted. This is referred to as the inactive season.
A USGA Course Rating™ and Slope Rating® represent the difficulty of a course played under normal or mid-season playing conditions. The unpredictability of off-season conditions - a lack of foliage, lessened green speeds, dormant rough - can greatly affect a course's difficulty. The course conditions during winter months are inconsistent with the way a course was rated; posting these scores could affect a player's Handicap Index®.
A Handicap Index is defined as "potential scoring ability on a course of standard playing difficulty." Consider a player on a course that, during the winter, was extraordinarily easy because the tees were moved up and there was no rough. Such a course would no longer reflect conditions under which it was rated, so accepting even a few scores could change a player's Handicap Index. The converse holds true for those facing quite difficult conditions, such as wet fairways or strong winter winds.
That's why many associations in areas where winter can be harsh set an inactive season, which often lasts from November to the middle of March. To provide consistency in posting of scores across a state or region, all clubs within the association's jurisdiction, whether member clubs of the association or not, must follow the inactive season.
While a darkened handicap computer terminal is a fairly strong indication of an inactive season, it is the player's responsibility to know whether the course on any given day is in its active or inactive season. This is important not only at the end or beginning of a season, but when a player posts a score from other than their home club.
What if the players had been on vacation in a warmer climate? It is likely that the course played was in its active season, so the round they played on vacation must be posted even if the home course is inactive.
A club must accept all away scores and may not eliminate acceptable scores from a player's record. Late-season play can be one of the unexpected joys of the game. If the club is in an active season, then these rounds can be used to help determine a Handicap Index. However, often they're nothing more than a pleasant way to spend an afternoon.
