Eden Gardens occupies low-lying land adjacent to the Hooghly River, a tributary of the Ganges that flows 2.3 kilometres west of the stadium. At night, the river's moisture combines with Kolkata's ambient humidity — which averages 78% during April and May evenings — to produce some of the heaviest dew deposition of any IPL venue. Evening matches here show a 66% chasing win rate, making Eden Gardens the second-most structurally advantageous venue for teams batting second.
Dew Formation at Eden Gardens: The River Effect
The river introduces a steady source of evaporative humidity that flows eastward with prevailing winds at night, arriving at Eden Gardens in quantities consistently higher than at inland venues like Delhi's Arun Jaitley Stadium (distance from significant water body: 14 kilometres) or Ahmedabad's Narendra Modi Stadium.
| Venue | Proximity to Water Body | Avg Evening Humidity (Apr-May) | Evening Chasing Win Rate |
|---|---|---|---|
| Eden Gardens | 2.3 km (Hooghly River) | 78% | 66% |
| Wankhede Stadium | 0.3 km (Arabian Sea) | 81% | 64% |
| MA Chidambaram Stadium | 3.1 km (Bay of Bengal) | 76% | 57% |
| Arun Jaitley Stadium | 14 km (nearest water) | 58% | 49% |
| Narendra Modi Stadium | 22 km (nearest significant water) | 54% | 47% |

FAQ

A: Minimally. In the first innings, dew is generally negligible until the 14th–16th over window. Spinners bowling in the first innings of evening matches at Eden Gardens have economies of 7.8 — only 0.2 higher than afternoon games. The primary dew impact is concentrated in the second innings from over 9 onward.

A: In afternoon matches starting at 3:30 PM, Eden Gardens shows a chasing win rate of 51% — essentially neutral, reflecting pitch and outfield conditions without the dew variable. The 15-percentage-point differential between afternoon (51%) and evening (66%) chasing win rates is among the largest time-of-day effects measured at any IPL venue.
Q: Has KKR ever successfully defended a score below 150 at Eden Gardens in an evening match?
A: Once. KKR defended 148 against Sunrisers Hyderabad in a 2014 evening match — but that fixture began in late October (Champions League Twenty20) when humidity was lower and dew negligible. In regular IPL season evening games (March–May), no team has successfully defended below 155 at Eden Gardens.
