Dew in Cricket — How Evening Dew Affects T20 Matches and Tactics
Evening dew is one of T20 cricket's biggest hidden factors. Learn how dew affects swing bowling, grip on the ball, and why teams choose to chase on dew-affected grounds.
Dew is condensation that settles on the outfield and pitch during evening play, particularly in the subcontinent and at grounds in warm, humid conditions. In day-night T20 matches, the team batting second often benefits from dew — the outfield becomes faster (balls race to the boundary), and the wet ball is harder for bowlers to grip, reducing swing, seam movement, and the ability to bowl cutters effectively.
How Dew Favours the Chasing Team
When dew is heavy, the bowling team in the second innings struggles to maintain a dry ball — fielders towel it off constantly but it gets wet again within deliveries. This neutralises grip-dependent skills: swing requires a dry lacquered ball; cutters require grip on the seam; leg-spin and off-spin lose their bite. The batting side can play more freely knowing the bowlers cannot generate the same movement as in the first innings.
The Toss and Dew
Dew is one of the primary reasons captains who win the toss at subcontinent grounds choose to field first in T20 matches — they bowl in the drier first innings before dew sets in, and their batters benefit from a quicker outfield in the second innings. At grounds where dew is predictably heavy (Mumbai's Wankhede, Kolkata's Eden Gardens, Dubai International Stadium), winning the toss and chasing is almost a reflex decision.
Frequently asked questions
Why does dew affect cricket bowling?
A wet ball is harder to grip, making it difficult to bowl swing, cutters, or spin. Bowlers lose their primary weapons, making batting easier in the second innings when dew settles on the field.
Does dew affect all cricket formats equally?
Dew most affects T20 and ODI matches played under lights in humid conditions. Test matches play across multiple days, so dew is less decisive — though day-night Tests in the subcontinent can still be dew-affected.
What can bowlers do about dew?
Bowlers can try to dry the ball more frequently on their clothing or ask fielders to use towels. Some teams bowl slower cutters or off-pace deliveries that rely less on conventional grip. There is no complete solution — dew significantly levels the playing field in the second innings.
