Weather and Reserve Days: How Cricket Manages Interruptions

Rain delays, bad light, and outfield floods interrupt cricket matches regularly — particularly in England, the Caribbean, and during the monsoon-adjacent seasons in South Asia. Test cricket has DLS for rain-affected results; ODIs have reserve days in major tournaments; T20 matches can be reduced and replayed with adjusted targets. This guide covers the full system for handling weather interruptions.

Cricket's approach to weather: the sport is played in open-air stadiums with no cover for the playing field (the pitch is covered when rain falls, but the outfield and surrounds cannot be protected). Play stops when: rainfall makes the pitch or outfield unplayable (standing water on the outfield, soft pitch); light becomes insufficient for safe play (the batting side can appeal for bad light — the umpires then judge whether conditions are safe using a light meter); or the pitch becomes dangerous (extreme surface deterioration). The resumption of play is at the umpires' discretion — they assess the outfield condition after rain stops and determine how long is required for the ground to drain.

Bad Light Rules

Bad light in Test cricket: the batting team can appeal for bad light at any time, and the umpires must offer the batting team the option to leave the field if they judge light is inadequate. The batting team always has the choice to continue playing in bad light (they would typically accept bad light if their team is chasing and time is short, as bad light reduces play time and benefits the team batting for a draw). In limited-overs cricket, bad light is handled differently — floodlights or artificial lighting are now standard at most international venues, removing bad light as a factor in day-night matches. In day-night Tests, the pink ball is used precisely because it is more visible in fading light and under floodlights than the traditional red ball.

The 1999 World Cup South Africa rain incident: South Africa vs Sri Lanka in the 1999 World Cup Super Six stage produced one of cricket's most famous weather controversies. South Africa needed 22 runs from 13 balls to win; rain fell; under the then-scoring calculation method (not DLS but the Average Run Rate method), South Africa's target when play resumed was recalculated to 22 runs from 1 ball — an impossible target. South Africa were eliminated. The incident directly accelerated the ICC's adoption of the Duckworth-Lewis Method (DLS) as the standard rain-interruption calculation for all ICC events. The 1999 South Africa rain-out remains cricket's most infamous weather controversy because the calculation method produced a manifestly unfair result — not a borderline case.

Reserve Days in Major Tournaments

Reserve days in ICC tournaments: for knockout matches in ICC events (semi-finals, finals), a reserve day is allocated — an extra day scheduled after the original match day to complete the match if weather prevents completion on the first day. The reserve day is used only for knockout matches (group-stage matches that cannot be completed are recorded as no result, with points shared). In the 2019 World Cup semi-finals: India vs New Zealand (Old Trafford) was extended to the reserve day after rain interrupted play on the original day — New Zealand were eventually bowled out for 239, India were bowled out for 221 (New Zealand won by 18 runs). The reserve day effectively extended the match into a second day of play.

Minimum Overs for a T20 Result

Minimum overs for a valid T20 result: in T20 International cricket, a result requires at least 5 overs to have been bowled (or attempted) in each team's innings. If the match is reduced by rain to fewer than 5 overs per side, the match is abandoned with no result. For a reduced-overs match between 5 and 20 overs, DLS calculates the target based on the resources available. In practice, T20 venues with drainage systems and covered pitches can resume play within 20-30 minutes of light rain — the ICC's push toward day-night T20Is with floodlights has reduced weather abandonment rates significantly in the 2010s-2020s compared to the day-only T20 era.

Frequently asked questions

What happens if it rains during a cricket match?

If it rains during a cricket match, play is suspended immediately: the pitch is covered, the players leave the field, and the groundstaff work to protect the playing surface. The umpires inspect the conditions periodically and determine when it is safe to resume play. If significant playing time is lost, the DLS (Duckworth-Lewis-Stern) method adjusts the target for the team batting second. If too much time is lost (fewer than the minimum overs threshold), the match is abandoned with no result. In Test cricket, missed sessions are not usually recovered — the match simply has fewer overs than the standard 90-overs-per-day allocation, and results in draws being more common if substantial time is lost.

What is a reserve day in cricket?

A reserve day in cricket is an additional day scheduled after the original match date specifically for knockout matches in ICC tournaments — if rain or other weather prevents the match from being completed on the original day, play continues on the reserve day from where it was interrupted. Reserve days are only used for knockout matches (semi-finals and finals); group-stage matches that cannot be completed are declared no results. The reserve day policy means that ICC tournament knockout matches are almost always completed to a result — weather cannot eliminate a team from a tournament by failing to allow enough overs to be played.

What is the minimum number of overs for a T20 match?

A T20 International match requires a minimum of 5 overs per side to constitute a valid result. If rain or bad light prevents 5 overs being bowled in either team's innings, the match is abandoned as a no result. When a T20 match is reduced (between 5 and 20 overs per side), the DLS method calculates a revised target for the team batting second. In ICC T20 World Cup group stages, a no result is treated as if the points were shared (both teams receive 1 point); in knockout stages, the reserve day is used to complete the match if the original day is rained off.
