When Does Flag Football Season Start?
Flag football runs in the spring and fall at most levels. NFL FLAG has two seasons per year. Girls high school flag football is booming as a spring sport. With the 2028 Olympics driving growth, here's everything you need to know about when flag football season starts.
Flag football is one of the fastest-growing sports in the United States, and for good reason. It's accessible, affordable, and now it's headed to the Olympics. Whether you're signing your kid up for NFL FLAG, coaching a high school girls program, or joining an adult rec league, the first question is always: when does flag football season start?
The short answer: most flag football programs run two seasons, spring and fall. The spring season starts in March or April. The fall season starts in August or September. High school girls flag football is typically a spring sport. And with the 2028 Los Angeles Olympics including flag football for the first time, expect even more programs and opportunities every year.
Below, we break down the timing for every level so you can plan ahead and get your team's custom flag football uniforms ordered before the first game. New to the sport? Start with our flag football rules guide and equipment checklist.
NFL FLAG
The largest youth flag football program in the country. Two seasons per year.
Spring Season: March/April to May/June
The NFL FLAG spring season is the primary season in most regions. It typically starts in March or early April and runs through May or early June. Games are played on weekends, usually Saturday mornings, with one practice per week on a weeknight. The spring season is popular because the weather is ideal for outdoor play and it doesn't compete with the school football schedule.
Registration for spring usually opens in January or February. NFL FLAG leagues are operated by local partner organizations, so exact dates vary by location. Check your local NFL FLAG affiliate for specific registration deadlines. Spots fill up quickly in popular areas, so don't wait.
Fall Season: August/September to October/November
The fall season runs alongside the NFL regular season, which adds excitement for young players. Games start in late August or September and wrap up in October or November. Fall registration typically opens in June or July. In some areas, fall is the more popular season because families associate football with fall weather and NFL Sundays.
NFL FLAG Regionals and Championships
NFL FLAG hosts regional tournaments and a national championship event. Teams qualify through their local leagues and regional competitions. The national championship, held during Pro Bowl weekend, brings together the best youth flag football teams in the country. It's a great goal for competitive teams and a showcase for the sport's growth.
Girls High School Flag Football
The fastest-growing high school sport in America. Spring season in most states.
Season: March to May (Spring Sport)
Girls high school flag football is a spring sport in most states that have sanctioned it. The season runs from March through May, with regular season games during the week and playoffs in late May or early June. Florida has had sanctioned girls flag football since 2003 and serves as the model for other states. The sport has exploded in popularity, with over 20 states adding it as an official high school sport as of 2025.
Most girls flag football programs play 5-on-5 on a smaller field (80 yards by 40 yards or similar). Games are fast-paced and high-scoring. Many programs are brand new, so there's an incredible opportunity for athletes to be part of something from the ground up. Check out our flag football rules guide for the specifics.
Growth Driven by the Olympics and NFL
Two major forces are driving the growth of girls flag football: the NFL's investment in the sport and the inclusion of flag football in the 2028 Los Angeles Olympics. The NFL has funded pilot programs in dozens of states, providing equipment, coaching education, and financial support to launch new programs. Olympic inclusion means flag football athletes will have a pathway to the highest level of competition, which is driving interest from female athletes across other sports.
Getting a Program Started
If your school doesn't have girls flag football yet, it may be coming soon. Many states are in the process of adding it. Contact your state high school athletic association to see the status. In the meantime, some schools run club programs or participate in leagues organized by local flag football organizations. The barrier to entry is low since flag football requires minimal equipment and can use existing fields.
Youth Recreational Flag Football
Low-cost, low-contact, and a great introduction to football.
Spring and Fall Seasons
Youth rec flag football follows the same spring/fall pattern as NFL FLAG. Programs are available through community recreation departments, YMCAs, Boys and Girls Clubs, and independent organizations like i9 Sports. Age divisions typically cover 4 to 5 year old, 6 to 8, 9 to 11, and 12 to 14 brackets. Most leagues are co-ed at younger ages.
Seasons run 6 to 10 weeks with one game and one practice per week. Registration costs are low, typically $50 to $150, and usually include a team jersey. The focus at the rec level is fun, fundamentals, and sportsmanship rather than intense competition.
Winter Indoor Flag Football
Indoor flag football leagues are growing in popularity, especially in northern states where winter weather limits outdoor play. These leagues run from January through March in indoor sports facilities or gyms. The field is smaller and games are faster-paced. Indoor leagues are a great option for keeping kids active during the winter and building skills for the spring season.
Adult Flag Football
Recreational and competitive options for players 18 and older.
Year-Round Leagues
Adult flag football leagues run year-round in most major metro areas. Spring and fall are the primary seasons, but summer and indoor winter leagues are common too. Organizations like FLAG Football League, local rec departments, and corporate sports leagues offer opportunities for all skill levels. Formats include 5v5, 7v7, and 8v8, with both co-ed and single-gender divisions.
For competitive adults, national and international flag football tournaments happen throughout the year. The American Flag Football League (AFFL) and various USA Football events offer high-level competition. With the Olympics coming in 2028, expect the competitive adult flag football scene to grow significantly.
The 2028 Olympics and What It Means
Flag football's biggest moment is coming. Here's how it changes everything.
Flag football will make its Olympic debut at the 2028 Los Angeles Games. Both men's and women's competitions will be featured, playing 5-on-5 on a standard flag football field. This is a seismic moment for the sport, and its effects are already being felt.
More high school programs: States are racing to add girls flag football as a sanctioned sport, knowing that Olympic inclusion will drive demand. The NFL is funding the expansion, and state athletic associations are fast-tracking approval.
College programs coming: With the Olympics creating a pathway for elite athletes, colleges are beginning to explore adding flag football programs. The NAIA has already announced plans for women's flag football, and the NCAA is expected to follow.
Youth participation surge: Olympic sports see massive participation increases in the years leading up to and following their debut. Flag football's low equipment costs and accessibility make it perfectly positioned for a participation boom.
What this means for your team: Whether you're starting a new program or growing an existing one, now is the time to get ahead. Order girls flag football uniforms or team uniforms that make your program look professional from day one. Build the culture early, and you'll attract athletes who want to be part of something special.
Pre-Season Prep Checklist
What to do before flag football season starts.
Register on time
Registration for spring flag football usually opens in January or February. Fall registration opens in June or July. Popular age groups fill up fast, so set a reminder and sign up early. Check your local NFL FLAG affiliate or recreation department website for exact dates.
Get the right cleats
Football or soccer cleats with molded rubber studs work great for flag football. Avoid metal cleats since most leagues don't allow them. Cleats provide the traction needed for quick cuts and direction changes that flag football demands. For younger kids, affordable cleats are fine since they'll outgrow them quickly.
Order team uniforms
Custom flag football uniforms need 4 to 6 weeks for production. For spring seasons starting in March, order in January. Secondslide makes lightweight, moisture-wicking jerseys perfect for flag football. For girls high school programs, check out our girls flag football collection.
Learn the rules
Flag football rules differ from tackle football in several important ways. No blocking, no tackling, different first-down rules, and specific flag-pulling mechanics. Review our flag football rules guide so coaches and players know what to expect. Many penalties in youth flag football come from players who haven't learned the rule differences.
Practice catching and throwing
Flag football is a passing-heavy game. The best thing players can do to prepare is practice throwing and catching a football. Even 15 minutes a day of playing catch improves route running, timing, and confidence. Use an age-appropriate size ball (Pee Wee for ages 6 to 9, Junior for 9 to 12, Youth for 12 to 14).
