The Dew Factor in Cricket: How Evening Moisture Affects Play

What Is the Dew Factor?

Dew forms on grass surfaces and the cricket ball during evening play — especially in tropical and subtropical climates common to India, the UAE, Sri Lanka, and the Caribbean. As air temperature drops after sunset, moisture condenses on the outfield, making the ball wet and slippery. This significantly impacts swing, spin, and fielding.

How Dew Affects Bowling

• A wet ball cannot be polished to maintain the shine differential needed for swing — swing bowling becomes ineffective
• Spinners find a wet ball hard to grip and generate rotation — spin becomes less dangerous
• Bowlers struggle to grip the ball consistently — accuracy suffers
• Fielders find the ball slippery — drops and misfields are more common in heavy dew

How Dew Favours Batting

When bowling is handicapped by dew, batting becomes easier. The outfield is faster as the grass is wet — shots reach the boundary more quickly. Without swing or spin, bowlers must rely on pace and variation alone. This makes the second innings of a day-night T20 or ODI in heavy dew conditions heavily weighted toward the batting team.

The Toss Decision and Dew

In conditions known for dew, winning the toss and choosing to bowl first — so that your team bats in the dew-affected second innings — is often the strategically correct decision. This creates an interesting paradox: the team bowling in the first innings sets a target while conditions are good for batting, then receives the ball in the second innings when dew has made bowling harder.

Dew Management

Groundstaff use absorbent towels and manage pitch covers to reduce dew on the playing surface. In-match, umpires regularly wipe the ball dry, and bowlers use sawdust (in wet conditions) on their hands for grip. However, these measures only partially mitigate the impact of significant dew.
