Rain Threat Looms Over RCB vs CSK IPL Clash in Bengaluru

When Royal Challengers Bengaluru (RCB) take on Chennai Super Kings at M Chinnaswamy Stadium on IPL 2025 match, a rain and thunderstorm alert from the India Meteorological Department could turn the showdown into a wash‑out. The toss is set for 7:00 PM IST, with the first ball slated for 7:30 PM, but a 76% chance of showers between 5 PM and 6 PM is already lighting up forecast maps.

Why the Weather Matters This Time

Earlier this season, a downpour in Mumbai forced a high‑stakes match to be reduced to 15 overs per side, costing both sides crucial points. This time, the stakes are even higher because RCB sit just one win away from the top of the table.

According to InsideSport.in, daytime temperatures will hover around 32 °C, slipping to a cooler 22 °C after dark. Humidity will cling at 63% during the day and rise to 77% at night – sticky, but not unbearable for players used to Bengaluru’s monsoon quirks.

• Rain probability at 5‑6 PM: 80%
• Rain probability at 7‑8 PM: 50%
• Thunderstorm risk 8‑9 PM: 26% (according to AccuWeather)
• Overall match‑window chance of precipitation: 43‑78% across services

Team Preparations Disrupted by the Drizzle

Virat Kohli, the star batsman for RCB, was seen fighting for a quick 45‑run sprint in the nets on Friday, May 2, when a sudden downpour drenched the outfield. "We just had to pack up and wait for the rain to pass," Kohli told NDTV Sports. His partner, opening batsman Devdutt Padikkal, laughed that the wet grass felt more like a water‑park slide than a practice pitch.

On the CSK side, a similar scenario unfolded. The squad’s morning session was abandoned after just ten overs, and captain MS Dhoni (who, at 43, is still the face of the franchise) nodded that the rain was "just part of the game in India". A quote from LatestLY reads: "We’re ready to adapt, whether that means a reduced innings or a strategic shuffle at the crease."

Playoff Implications if the Match Is Called Off

Should the umpires have to call off play after the toss, both teams will be handed a single point. That would catapult RCB to 15 points from 11 games, nudging them ahead of Mumbai Indians, who sit on 14 points. For CSK, the point is a modest consolation – they are already out of contention according to RevSportz.in.

Analyst Rohit Sharma (not the Mumbai captain, but a cricket statistician) noted, "A wash‑out benefits the team that’s already near the top, because a point can be the difference between home‑ground advantage in the semis and a tough away game."

What the Pitch Could Have Offered

The Chinnaswamy ground is famed for short boundaries and a relatively flat outfield – a recipe for high scores when the weather cooperates. Last year, RCB posted a 219‑run total there, the highest in the tournament. If the rain holds off, fans can expect a batting fireworks display, especially from Kohli, who averages 48.6 at home.

But the looming thunderheads may force the officials to shorten the game to 20 overs per side, or even invoke the Duckworth‑Lewis‑Stern method mid‑innings. That unpredictability is why many fans are already debating whether to buy tickets or stream the match from a dry couch.

Expert Take on the Forecast Discrepancies

Why do the models disagree so wildly? Meteorologist Ananya Rao of the India Meteorological Department explained that Bengaluru’s micro‑climate creates “pockets of convection” that short‑range models struggle to capture. "One minute it’s clear, the next you have a sudden squall," she said on a recent interview.

AccuWeather’s team pointed to satellite data that shows a low‑pressure system moving eastward across the Deccan Plateau, which could trigger scattered showers. Meanwhile, BBC Weather’s more conservative outlook suggests a 22% chance of rain at the exact start time, betting on the city’s diurnal heat to push clouds away.

What’s Next for the Two Franchises

RCB’s next fixture is against the Rajasthan Royals on May 7, a match that could lock in their top‑seed status if they manage a win. CSK, already out, will likely use the remaining games to give younger talent a taste of IPL pressure.

Stadium officials said they have sandbags and a high‑capacity drainage system ready, but even the best infrastructure can’t guarantee a full 40‑over spectacle when the sky opens up.

Historical Weather Interventions in the IPL

Since the IPL’s inception in 2008, weather has played spoiler more than a dozen times. The most infamous episode was the 2019 rain‑shortened final in Hyderabad, where the board had to declare a result after just 30 overs per side. In Bangalore, the 2013 rain‑affected match between RCB and Delhi Capitals saw an unprecedented three‑hour delay before play resumed.

These precedents have forced the Board of Control for Cricket in India (BCCI) to refine its rain‑rule protocols, ensuring that point allocations and net‑run‑rate calculations remain transparent.
