Rates a game of cricket, a session in the nets or a backyard match. Rain stops play, so even drizzle holds the score down, and rain in the last few hours leaves a wet outfield. It's a long day in the sun, so the heat counts too. GoDay finds the best 4-hour window of each day's daylight.
Any rain holds the score at 5, and rain over 0.3 mm an hour, enough to bring the covers on, holds it at 2. A thunderstorm holds it at 1, and one due within two hours at 3. More than 8 mm of rain in the last 6 hours (a wet outfield) holds it at 4, and a feels-like above 40°C (104°F) at 3.
Daylight counts too: at dusk the score is held at 4, and once it's dark at 1.
GoDay treats any rain as trouble for cricket: drizzle holds the score at 5, and anything heavier at 2. Look along the day for a dry 4-hour window. Rain earlier in the day can still delay the start while the outfield dries.
At dusk the score is held at 4 and after dark at 1, because bad light stops play. If your ground has lights, go by the other conditions.
GoDay rates a feels-like of 16 to 30°C (61 to 86°F) as ideal. Past 30°C (86°F) it starts taking points off, past 38°C (100°F) it counts against the score, and past 40°C (104°F) the score is held at 3.
