Rates a game of Australian rules football, a training run or a kick-to-kick in the park. Footy is played in the wet, so drizzle hardly counts and light rain costs a couple of points. Wind counts for more than in most sports, because a long kick is where it shows. GoDay scores each hour and finds the best 2-hour window of each day.
Also on the page, but not in the score: wind direction.
A thunderstorm holds the score at 1, and one due within two hours at 3. A feels-like above 36°C (97°F) holds it at 3. More than 50 mm of rain in the last day holds it at 3, since grounds are often closed after that much, and rain over 8 mm an hour holds it at 4. Gusts over 75 km/h (47 mph) hold it at 3.
Daylight counts too: once it's dark the score is held at 5.
Up to 15 km/h (9 mph) barely touches a kick, and up to 25 km/h (16 mph) is still fine. Past 35 km/h (22 mph) the wind counts against the score, and it weighs more for footy than for soccer or rugby because of the long kicking.
Almost always. Drizzle hardly counts, light rain costs a couple of points, and a greasy ball is part of winter footy. After a very wet day the ground is the question: past 50 mm in the last 24 hours the score is held at 3.
Most clubs train under lights, so the dark only holds the score at 5. For a kick in an unlit park, check the daylight card for sunset.
