Dew Factor in Cricket: Why Captains Fear It at Night Games

In day-night cricket played at grounds with warm, humid evenings, dew accumulates on the outfield and pitch as temperatures drop after sunset. The ball absorbs moisture, the outfield becomes slippery, and bowlers lose all ability to maintain a dry surface for swing or seam movement. Dew has changed the outcome of World Cup finals.

How Dew Affects the Ball

• The ball becomes wet and slippery — bowlers cannot grip it cleanly for swing
• Reverse swing disappears — the surface needs to be dry on one side to reverse
• The outfield becomes quicker as dew lubricates the grass — boundaries are easier to reach
• Fielders struggle to stop the ball cleanly with damp, heavy turf beneath them
• Spin bowling loses effectiveness — the ball skids through rather than gripping

Why Chasing Teams Benefit

Teams batting second typically face dew conditions in their innings. The ball is easier to hit through the dewy outfield, bowlers cannot extract swing or seam, and boundaries come more freely. This creates a structural advantage for the chasing side in day-night matches at certain venues — especially in the Indian subcontinent. The ICC World Cup 2023 saw several matches where the team chasing won because dew neutralised the bowling attack.

How Teams Counter Dew

• Captains win the toss and elect to field first — let the opposition bat without dew, then chase under it
• Groundstaff towel the ball after every boundary — legal if done before the bowler's run-up
• Bowlers use slower balls, cutters, and variations that do not require swing to be effective
• Batters at the start of the second innings try to play out the early overs quickly to maximise the dew advantage later
• Teams with strong death bowling use yorkers — which are less reliant on the ball's surface condition

Venues Most Affected by Dew

Dew is worst at subtropical venues with warm, humid evenings — Kolkata, Mumbai, Dubai, Sharjah, and Dhaka are notorious. At higher-altitude or dry-climate venues (Johannesburg, Christchurch, Cape Town) dew is rarely a factor. England and Australia rarely see dew at home because their temperatures are cooler.

Can the Pitch Itself Get Dewy?

Yes — in extreme conditions, the pitch surface also accumulates dew. This slows the ball off the surface and prevents seam movement from the pitch. A dry, firm pitch can become soft and slow by the 30th over of a day-night ODI. The square leg umpire sometimes signals to stop play if the pitch is dangerously wet, though this is rare.
