The tournament may have changed its name to the AT&T some years back, but the climatic vagaries that can make the course so challenging are still known as ``Crosby Weather.'' The tournament, which dates back to 1937 when Bing Crosby started his annual ``clambake,'' has seen rain, snow, sleet and winds play havoc with the course, the players and the spectators. However, a look at the weather statistics shows that it's not quite the constant deluge we often envision.

Probably the most memorable example of "Crosby weather'' was back in 1962, when the final day of the tournament had to be delayed until Monday because of a half-inch of snow on Saturday night and sleet on Sunday. In the 65 years that the tournament has been played, it has been shortened several times and the final day has been postponed on occasion. But 1996 was the only time it has been canceled. 

In the past 47 years there have actually been 21 when it has not rained on any of the days during the tournament.  In the same period there have been seven occasions, most recently in 2019, when it rained all four days. In the other 17 years, it rained one day on eight occasions, two days for another eight years and three times that it rained three of the four days. But in 1998 when it rained three days there was 2.74 inches recorded and the tournament ended up being postponed for about six months.

Historically, the chance of getting rain in Monterey on any single day from January through the first week of March is about 35 percent, with an average amount of 0.14 inches.
