Indoor and outdoor sports and activities in Marin at the youth, prep, college, adult and recreational levels have all been affected by the poor air quality from the North Bay fires.

All Marin County high school games and practices have been postponed through Sunday as fall sports teams — cross country, football, girls golf, girls tennis, girls volleyball, water polo — have been unable to practice or play all week. MCAL commissioner Susie Woodall announced the weekend cancellations to athletic directors and school administrators Thursday morning on Marin County public health officer Matt Willis’ recommendation.

While the possibility of rescheduling remains, Woodall said she believes all games will eventually be canceled.

“This is not a healthy situation for anybody,” Woodall said. “I have not experienced the rain like we had in the winter, and that’s not even in the ballpark of what we’re dealing with now.

“I know there are a few big matches with tennis and volleyball, but we can’t make everybody happy. Everybody is working as hard as we can in this very difficult situation. The situation is not going to be ideal, but we ask for everyone’s patience and cooperation.”

All Marin County high schools and colleges will be closed Friday. Marin Health and Human Services released a public health advisory on Thursday, stating that “when air quality is unhealthy, activities such as athletic events or practices should be canceled or rescheduled. Stay indoors with windows closed as much as possible.”

As of 1 p.m. Thursday, San Rafael registered the second-worst air quality in the nation behind Houston, according to the U.S. Environmental Protection Agency. San Rafael’s air quality index reading was 164, per EPA website airnow.gov. Between 51 and 100 is considered healthy.

If the MCAL girls golf championship — which is scheduled for Monday at Indian Valley Golf Club in Novato — cannot be played, Woodall said undefeated Terra Linda, the regular-season champions, will earn the league’s automatic berth to the North Coast Section playoffs the following week. Other teams can apply at-large. The league — who will make a decision Sunday on whether to play Monday — would also mathematically determine its four qualifiers for the section’s individual championship tournament.

The NCS playoffs begin Nov. 1 for water polo, Nov. 7 for girls tennis, Nov. 10 for football and Nov. 18 for cross country.

“The bottom line is we’re doing the best we can, and the people up north are not concerned with win-loss records,” Woodall said. “They have more on their minds right now.”

College sports

While the Dominican University volleyball team hosted Concordia University Irvine Wednesday night as scheduled, the school has tweaked the upcoming slate of games. The Penguins’ men’s and women’s soccer teams moved its Saturday matches against Notre Dame de Namur to Belmont, and the Dominican men’s lacrosse team canceled its exhibition against UC Davis on Sunday.

Dominican’s midnight madness basketball event Saturday night has been canceled, as well as all recreational and club sports until further notice. The women’s basketball team’s tipoff brunch on Sunday was also canceled.

College of Marin hasn’t played a home game all week and all three contests scheduled for Friday have been canceled.

Around the county

• The YMCA in Terra Linda, which generally draws 1,000 people per day, has remained steady, said David Dreoch, an employee of the nonprofit. Dreoch said while traffic has been typical, the YMCA’s phones “have been ringing off the hook” with questions about donations. For information on what types of donations are needed, Dreoch said, visit sonomacounty.recovers.org.

• Mt. Tam Racquet Club general manager Rod Heckelman said the club’s 85 weekly fitness classes have been about half-attended this week. The club is strongly discouraging use of the outdoor tennis courts, which remain empty. The indoor courts are open.

“I think people are realizing that exercise in itself is a no-go, and I guess that’s been the case with all of our activities,” Heckelman said. “One thing I’ve noticed is people are looking to raise funds, and I think that’s great. They’re seeing and sensing the need to get involved.”

• Annabelle Anopol of Novato’s StoneTree Golf Club said about half of the club’s members have been golfing — some with protective masks — despite the course being filled with smoke. The club has received calls to reschedule weekend events, including weddings.

“We’re just letting everyone know it’ll be an evening-to-evening basis based on air quality,” Anopol said. “If it’s too unsafe, we’ll let members know we’re closing, but we’re still open as of now.”

• North Bay Aquatics, which features programs ranging from youth to master’s, has canceled all practices and training sessions through Sunday.

“We haven’t done anything all week,” head coach Ken DeMont said. “As soon as the air quality index goes over a certain amount, all pools close. This is training time right now. It hurts, but you can only control what you can control. It’s been a very strange week.

“Obviously what we’re doing is not the most important thing right now.”

• Josh Kalkstein, the director of coaching at Marin FC, said the soccer club hasn’t had a single training session this week and has canceled games and practices through the weekend.

“We have several families that live in impacted areas, so this is hitting our Marin FC community pretty hard, as well,” Kalkstein said.

• The Dixie Youth Soccer Association canceled all of its weekend games.

“DYSA recommends keeping players inside,” the club’s news release said. “We know a lot of people are directly affected by this unfolding situation in some way — family, friends, coworkers. Please stay safe as we work together through this difficult time.”

• Absolute Volleyball Club, which canceled practices every day this week, will determine on Friday if its teams will compete this weekend.

One Absolute staff member lost their home in the fires after evacuating Monday morning, club owner and director Konrad Ott said.

“It’s really been a horrific event,” Ott said. “We plan to hold fundraisers for victims of the fires, all the families. People can also drop off any clothes or supplies to our San Rafael facility (2145 Francisco Blvd E, San Rafael) whenever they’d like.”

• This Sunday’s Can Do! 5K, fun run and family festival was rescheduled for Dec. 3. For more information, please email info@cando4schools.org.

• North Bay Youth Football, a youth league with teams spanning from San Marin to Napa, canceled its slate of regular-season-finale games this weekend. President Dennis Reeger said the league will worry about postseason when it’s safe to resume play.

“What’s going on in our community is more important than any sports,” Reeger said. “There are a lot of families hurting right now. Unfortunately some people in our organization have lost homes and properties, so a lot of our teams are stepping up and trying to help out when they can.

“It’s amazing to see, as a community, everyone come together and help each other. I’m so proud of everyone.”
