The women's singles final of the Chennai Open was postponed by a day after thick smog engulfed the city and pushed air quality readings to alarming levels, with defending champion Janice Tjen publicly criticising the tournament organisers for wanting the match to go ahead despite the dangerous conditions. The final between Indonesia's Tjen and Poland's Magda Linette will now be played on Monday morning, on the tournament's reserve day.
Tjen, the defending champion and world number 75, shared a video on Instagram showing how thick smog had reduced visibility around the SDAT Tennis Stadium in Nungambakkam, along with an air quality index reading of 1,556. She claimed that the organisers were not willing to postpone the match and wanted it to go ahead despite the pollution levels. Tjen also reshared a post by her coach, Christopher Bint, making the same claim about the organisers' intentions.
An air quality reading of 1,556 is extremely high and far exceeds India's official air quality index scale, which ends at 500. Readings above 500 fall into the severe-plus category, at which point the air is considered hazardous for everyone, and outdoor physical activity is strongly discouraged.
For professional athletes playing a high-intensity sport outdoors, the conditions were not merely uncomfortable but potentially harmful, and Tjen's decision to speak out publicly turned a scheduling problem into a wider debate about player welfare.
The final was originally scheduled to begin at 6:30 pm on Sunday, November 8, after the women's doubles final. But the match could not get under way as planned. Rain interrupted play through the day, and once the showers stopped, the organisers worked to dry the centre court and announced that play would begin at 9 pm.
By then, however, smoke from Diwali fireworks had covered the stadium, making it difficult to breathe and reducing visibility to the point where play was not possible.
The two players arrived briefly on centre court with their equipment bags before leaving again, and the match was subsequently suspended. The Women's Tennis Association later announced in an official statement that the final would be played at 11 am on Monday, November 9, the tournament's reserve day. "Due to unforeseen weather conditions, the women's singles final between Janice Tjen and Magda Linette has been postponed. The match will now take place tomorrow (November 9, 2026) at 11 am," the WTA said.
The Tamil Nadu Tennis Association confirmed the postponement and announced that spectators who had purchased valid tickets for Sunday's matches would be able to use the same tickets to enter the venue on Monday. The decision to stage the final on Diwali had already attracted criticism, with questions raised about the organisers' choice of date given the traditional fireworks celebrations across Chennai.
The impact of the celebrations was felt during the semi-finals as well, when the sound of firecrackers bursting outside the stadium repeatedly disrupted proceedings, and the noise became particularly pronounced on Sunday evening as Diwali celebrations gathered pace.
The episode has cast a harsh light on the air quality crisis that grips Indian cities every year around Diwali. In Chennai, air pollution levels rose sharply following the Deepavali celebrations, with several parts of the city recording unhealthy air quality on Monday morning.
According to real-time air quality data updated at 8:31 am on November 9, Chennai recorded a fine particulate matter (PM2.5) concentration of 109 micrograms per cubic metre, while PM10 stood at 132 micrograms per cubic metre. The locality of SM Nagar recorded the highest air quality index among the listed locations at 207, placing it in the severe category, and the deterioration was attributed to firecracker usage.
Delhi, meanwhile, slipped into the severe category in parts of the capital on Monday. At around 4:20 am, the ITO air quality monitoring station registered an index of 406, according to data from the Central Pollution Control Board. The capital's air quality had already been the subject of widespread concern after pollution levels soared to more than 50 times the World Health Organization's recommended limit on Deepavali night, as people defied the ban on firecrackers.
The Chennai Open is a WTA 250 tournament, the third edition of the event, and this year will mark the end of Chennai's tenure on the WTA Tour calendar, at least for the foreseeable future. The event has been moved to Manila in the Philippines for 2027, which makes the disrupted final an unhappy farewell for the tournament's Chennai chapter.
The week had already been affected by weather interruptions throughout, and the smog-affected final provided a fittingly chaotic conclusion.
Tjen entered the final as the defending champion, having won the title last year, and she was scheduled to take on Linette for the singles crown. The Indonesian has been one of the breakout players of the season, and the final was expected to be a competitive contest between two players with contrasting styles. Instead, the match became a story about air pollution, scheduling and the responsibilities of tournament organisers when conditions turn dangerous.
The question of when outdoor sport should be called off because of air quality has no clear answer in tennis. Unlike rain, which makes the court unplayable, pollution does not stop the ball from bouncing, and the decision to postpone rests on judgements about player health that organisers, officials and players themselves may weigh differently.
Tjen's public criticism suggests that, in her view, the organisers weighed the desire to complete the tournament on schedule more heavily than the health of the players. The organisers have not publicly responded to her claim.
The incident is the latest in a series of occasions on which air pollution has disrupted sport in India. Cricket matches in Delhi have been played in hazardous smog, marathons have been run in unhealthy air, and football and hockey fixtures have been affected by the annual deterioration in air quality.
Each time, the same questions arise: who decides whether conditions are safe, what threshold should trigger a postponement, and whether commercial and scheduling pressures are allowed to override health concerns.
For the Chennai Open, the immediate question is simpler: whether the final can be played on Monday morning in conditions that are safe for both players. The reserve day exists precisely for situations like this, and the 11 am start gives the city time to clear some of the overnight smog. But if the air quality remains poor, the organisers will face the same decision again, and this time with the whole tennis world watching.
The wider lesson extends beyond one tournament. As long as Indian cities record air quality readings in four figures after Diwali, outdoor sporting events scheduled around the festival will remain vulnerable to disruption. The Chennai Open final was postponed because of a combination of rain and smoke, but the smoke was the decisive factor, and it was a man-made one.
Until the air quality problem is addressed, players, organisers and spectators will continue to pay the price, one postponed final at a time.
