GREEN BAY, Wis., Dec. 1— The Green Bay Packers beat the Tampa Bay Buccaneers, 21-0, today in one of the snowiest National Football League games ever. More than 36,000 fans stayed home.
The scene was Lambeau Field, where the Packers played in the coldest N.F.L. game, the famed ''Ice Bowl,'' in which the Packers beat the Dallas Cowboys for the league championship, 21-17. The temperature on that day, Dec. 31, 1967, has been variously recalled as minus 16 or minus 17, but it has never been disputed that the wind-chill factor made it feel colder.
Only 19,856 fans attended today, compared to 36,586 who stayed home. Remaining unsold were 485 tickets. Twelve inches of snow had fallen at game time and about four more fell before the final gun. Snow blowers were used at halftime to clear off some of the snow. Winds gusted to 25-35 miles per hour, plunging the wind chill factor to zero.
Despite the weather, the Packers said their plan was to come out throwing. It worked, and the Tampa Bay coach, Leeman Bennett, could attest to that.
''They did not let the snow get to them. Lynn threw the ball just great,'' Bennett said of Lynn Dickey, the Pakcer quaterback.
''It was 85 degrees in Tampa, and they come up here and the snow's blowing. I know they're not used to that,'' Gerry Ellis, the Green Bay running back, said. ''It's kind of an advantage for us.''
The previous snowiest game also involved the Packers. In October 1984, 15 inches fell in Denver in a Monday night game won by the Broncos, 17-14.
The normally crowded Lambeau Field drew only die-hard fans and only a few hundred were in the stadium half an hour before the noon kickoff.
''I love it, it's May,'' Paul Coffman, the Packer tight end, said. ''This is what I come to play for. It slows everyone down to my speed.''
The last game played in Green Bay in a heavy snow was the Jan. 2, 1966 N.F.L. championship game in which N.F.L. championship game in which the Packers defeated the Cleveland Browns by 23-12. The fall was 3 1/2 inches that day.
Today's snowfall in Green Bay set a record for the date in the history of the local weather bureau, which dates back to the late 1880's.
