Dew and Its Effect on Cricket Matches
What dew is, why it appears in evening matches, how a wet ball and outfield change bowling, spin and fielding, and how captains respond at the toss.
Dew is a thin layer of water that forms on grass and other surfaces when the air cools in the evening. In cricket it matters because it can change conditions during a match, particularly in day-night games and evening T20 fixtures. Players and captains talk about it often, and it can influence the toss decision and the way both sides plan.
What dew is and when it appears
Dew forms when the temperature of a surface falls to the point where water vapour in the air condenses into droplets. This usually happens on clear, calm and humid evenings, because the ground loses heat quickly. In many parts of the world, including the Indian subcontinent, the Gulf and parts of Australia, the evening can bring heavy dew, especially at certain times of year. Cloud cover and wind reduce it, because they stop the ground from cooling as quickly.
Effect on the ball
The most obvious problem is a wet ball. Water makes the ball harder to grip, so bowlers find it harder to control their lengths and lines. Several effects follow:
- Spinners lose the grip they need to turn the ball and often struggle to land it consistently
- Seamers find it harder to hold the seam and may bowl more full tosses or wide deliveries
- Reverse swing and conventional swing become less effective
- Yorkers become harder to execute with a damp ball
Fielders also feel the difference. A wet ball can slip in the hand, which makes throwing and catching more difficult, and fielders may drop chances or miss run-out opportunities. Teams often use towels and replace balls where the playing conditions allow it, but they cannot completely remove the effect.
Effect on the outfield and pitch
Dew also settles on the outfield. A wet surface lets the ball travel faster along the ground in some cases, and it can make fielders less secure when diving or turning. On the pitch, dew can change the way the ball skids on, because moisture affects the grip between the ball and the surface. In some cases the pitch may become slightly easier to bat on, as the ball comes onto the bat more readily and spin has less effect.
Why captains often choose to chase
Because dew generally arrives in the second half of an evening match, the team batting second often gets an easier batting surface and a wetter ball. As a result, many captains prefer to field first when they expect heavy dew, so that their side can chase a target in the conditions that help batters. This has influenced toss decisions in a number of tournaments, and in some matches the toss is seen as a significant advantage.
However, the effect is not always decisive. Weather, pitch type and the opposition’s skill all play a role, and teams that bowl well in difficult conditions can still defend totals. Coaches often prepare for dew by practising with wet balls and discussing plans to cope with it.
How teams adapt
Bowlers can adapt with a few practical changes. They may use more cutters and slower balls that rely less on grip, bowl wider lines and use the pace of the batter rather than the movement. Teams can also work on running between wickets and try to limit the amount of time the ball spends on the ground. Support staff dry the ball between deliveries and keep towels at the boundary.
Batters, meanwhile, can take advantage by watching for the ball skidding on and by using the pace on the ball. Teams may promote hitters and focus on attacking, because bowlers are less likely to make full use of the new ball’s variations.
Managing the playing conditions
Match officials may allow a ball to be replaced if it becomes unplayable because of wetness, and some competitions have specific regulations about how the ball can be dried. Some tournaments also set start times to limit dew’s influence, although this often conflicts with television schedules and spectator preferences.
The wider picture
Dew illustrates how much conditions can influence the sport. It is a reminder that cricket is played outdoors and that nature can alter the contest in subtle ways. For fans and analysts, it is worth watching how both teams handle it, because the best sides combine good planning with quick adjustment to what they see on the day.
Frequently asked questions
Why does dew affect cricket?
It wets the ball and the outfield, which makes gripping, bowling, throwing and catching harder, particularly for spinners.
Why do captains often choose to bowl first when dew is expected?
Dew usually arrives later in the evening, so the side batting second often enjoys easier conditions, so captains often prefer to chase.
Can the ball be changed if it is too wet?
Umpires may replace a ball under the competition’s playing conditions, though the rules differ and the ball can usually be dried with towels.
