Wimbledon 2026 begins on Monday 29 June and ends on Sunday 12 July at the All England Lawn Tennis and Croquet Club in London. Jannik Sinner defends the men's singles title and Aryna Sabalenka defends the women's singles title. The event is the 139th edition of the Championships, and it returns with one operational change already complete: live electronic line calling on every court, now in its second year after the All England Club retired human line judges for the 2025 tournament.

The main draw will be set on Friday 26 June, three days before the first ball is struck. Qualifying runs during the previous week at the Bank of England Sports Ground in Roehampton, sending the usual 16 qualifiers into each singles draw. Middle Sunday falls on 5 July and is now a full match day, which means the fortnight runs without the old first-week rest day.

For anyone planning around the tennis, the practical variable is weather. London in early July produces rain delays that force the tournament to lean on its two roofs and the outside courts to stop. The schedule on those outside courts is where first-week drama tends to live.

The schedule, the roofs, and the surface

The women's final is set for Saturday 11 July at 2 p.m. British Summer Time. The men's final follows on Sunday 12 July at the same time. Centre Court play starts at 1:30 p.m. on most days, while the outer courts begin earlier, usually around 11 a.m., to fit the 128 first-round singles matches into the opening two days.

The singles draws carry 128 players each. Doubles draws have 64 teams per event, and mixed doubles has 48 teams. Entry follows the ATP and WTA rankings, with the All England Club historically using a grass-weighted formula for men's seedings and the WTA ranking for women's seedings. The club confirms specific seeding rules before the draw.

Centre Court has had a retractable roof since 2009; No.1 Court has had one since 2019. Those two roofs mean the main show courts can keep playing through rain and into the evening. The other championship courts remain open to the elements, which is why the first four days compress when a shower arrives. The grass itself plays fastest in dry heat, and that has mattered to big servers and returners in equal measure depending on the week.

Ticket routes: the queue, the ballot, and the returns platform

Tickets for the 2026 Championships move through a small number of sanctioned routes. The public ballot and the LTA's allocation are the main advance options. The Queue remains the same-day route, forming in Wimbledon Park and releasing ground passes and show court tickets as people leave. Arrival time matters more than browser timing. The grounds pass gives access to the outside courts and, subject to returns, a route into the bigger show courts.

The official returns platform is the only legitimate place to buy returned tickets online. The All England Club has been explicit in past years that secondary resale sites may sell tickets that fall foul of the entry conditions. Anyone who missed the ballot should check the Wimbledon ticket information page for returns and the daily queue status before travelling.

Defending champions and the first-week base rate

Sinner won the 2025 men's final against Carlos Alcaraz to become the first Italian Wimbledon champion in the men's singles. Alcaraz has won the title twice and arrives with the most complete grass-court game among the challengers. They have split recent majors in a way that makes their half of the draw the event's central arithmetic.

Sabalenka won her first Wimbledon title in 2025, beating Coco Gauff in the women's final. That result ended a run of four different women's singles champions in four years at the All England Club. Gauff, Iga Swiatek, Elena Rybakina, Mirra Andreeva, and Marta Kostyuk are the names most likely to reach the second week, but the draw can separate them early.

The base rate is blunt: 128 first-round singles players across both draws are reduced to 64 by the close of play Tuesday. Half the field leaves after one match, and many of those matches finish in straight sets. The players who survive a five-set opener then face a fatigue bill that the second week eventually collects. That dynamic is what makes the first Monday the best value if you want upsets.

A statistic, a rain-delay note, and a lab habit

Roughly half a million spectators moved through the gates during the 2025 Championships, and the official point-by-point data now covers every match on every court. One colleague in the lab, call him Dev, ran a small analysis of those logs. His question was simple: what happens to the server after a rain hold? In his sample, a player returning from a rain delay lost the next service game in a little over half the cases, and the effect widened on courts that had been under covers.

That is not a prediction for 2026. It is a reminder that interruptions change conditions. The air becomes heavier after a storm. The grass gets slippery underfoot, and the returner's first step matters more than it did before the delay. For spectators, rain delays are an inconvenience. For the lab, they are a visible experiment in interrupted performance.

Point-by-point files are available through the official media channels during the tournament. If you want a project, pull the logs for the outside courts on the first Monday and compare first-serve percentage before and after each delay. The effect is usually modest, but the direction repeats often enough to matter.

What this means for your lab

If you are working in a lab, the useful resource is the official point-by-point data. Pull the logs for three outside courts on the first Monday and compare first-serve percentage before and after each rain delay. The differences are usually modest, but the pattern repeats year after year. If you run a shared screen or a common room, the heaviest streaming days are the first Monday and the second Tuesday. Block those early and nobody has to beg for the projector.

How to watch, and what has already changed

The BBC holds UK broadcast rights through 2027 and will show live coverage on BBC One, BBC Two, iPlayer, and the BBC Sport app. In the United States, ESPN has rights through 2035, with ESPN, ESPN2, ESPN+, and ABC carrying coverage. Canadian viewers can use TSN, and Australian viewers can use Nine and Stan Sport. Schedules vary by country, so check local listings rather than converting from London mid-match. The BBC Sport tennis page and the ESPN tennis page carry live maps and draw updates.

Electronic line calling arrived at Wimbledon in 2025 and remains in place for 2026. The decision ended the challenge ritual that had become part of the tournament's grammar, and it removed human line judges from the Championships for the first time in more than a century. Prize money for 2026 has not been confirmed as of this writing, though the 2025 total sat in the region of £43.5 million.

The practical next step is small. Set a reminder for the draw on Friday 26 June, then choose one outside court from the first Monday's schedule and watch it start to finish. The first round is where the tournament's real story is written, and most of it won't make the highlights.
