History

The Halle Open was first held in 1993, when Henri Leconte won the inaugural title, and it has been one of the most prestigious stops on the grass-court calendar ever since. Played on the fast outdoor grass of the OWL Arena, the venue was purpose-built with a retractable roof, a rarity that has long shielded the event from the unpredictable German summer. The tournament was upgraded from an ATP 250 to an ATP 500 in 2015 and has carried several sponsor names over the years, from the Gerry Weber Open (1993 to 2018) to the Noventi Open (2019 to 2021) and, since 2022, the Terra Wortmann Open. No name is more synonymous with Halle than Roger Federer, who holds the records for most titles (10, the last in 2019 at the age of 37) and most match wins (69). Borna Coric is the youngest champion (21, in 2018), Florian Mayer the lowest-ranked (No. 192 in 2016) and the last home winner (also 2016), and both Federer and Jannik Sinner (2024) lifted the trophy while ranked World No. 1. The 2026 edition is the 33rd staging of the tournament and is led by tournament director Ralf Weber.

Tournament Data

Halle sits in the gently rolling country of North Rhine-Westphalia, at a modest elevation of roughly 100 metres (around 330 feet) above sea level. The OWL Arena's outdoor grass is historically one of the fastest and truest surfaces on tour, a quick, low-bouncing court that played no small part in Roger Federer's long love affair with the venue. Crucially, the centre court has a retractable roof, so rain rarely disrupts the schedule.

These are the characteristics to expect on Halle's grass:

Very high ace counts and a heavy premium on serve; the fast, low bounce rewards big first serves and flat, penetrating hitting
Short average rallies and first-strike tennis, with serve-plus-one patterns and clean ball-striking dominating
A true, reliable bounce that, combined with the pace, suits aggressive baseliners and shotmakers who take the ball early
High service-hold and tiebreak rates, so matches can swing on a handful of points and a single mini-break
The retractable roof keeps conditions consistent and play on schedule, largely taking the weather out of the equation on centre court

Note: the 2020 edition was not held because of the COVID-19 pandemic.

Weather

This week in Halle, conditions are seasonable and warming for mid-June in Germany. After a cool, partly cloudy start with highs around 17 C (62 F) for the opening day, the mercury climbs quickly, reaching about 22 C (72 F) on Tuesday and 26 C (78 F) by Wednesday, with only a moderate midweek shower risk. In any case, the OWL Arena's retractable roof means rain will not stop play on centre court, and the warm, dry spells should make the famously fast Halle grass play quicker still.

Key 2026 News and Storylines

The Big One: a French Open champion opens his grass season at home

After skipping the grass-court 250s to recover from his maiden Grand Slam triumph, new Roland Garros champion Alexander Zverev makes his return right here, as the top seed in front of a German crowd. Halle is the centrepiece of his grass preparation before Wimbledon, and the home favourite, twice a finalist at this event (2016 and 2017), will be desperate to finally convert on a wave of confidence. The catch: he has landed in a brutally strong ATP 500 field with no soft landing in sight.

Major Absences

Jannik Sinner (World No. 1, 2024 champion): NOT in the field. The top-ranked Italian, who won here in 2024, is taking a lighter route into Wimbledon and does not play Halle this year.
Carlos Alcaraz (Spain): OUT, still recovering from the wrist injury that forced his withdrawal from Roland Garros.
Novak Djokovic: NOT entered, in keeping with his minimal grass-court tune-up schedule.

Key Players In (or Status to Watch)

Alexander Zverev (top seed, Germany) is IN. The new French Open champion and home favourite plays his first event since Paris, and is twice a Halle finalist. The serve and the fast surface suit him; the only question is freshness after an emotional fortnight.
Felix Auger-Aliassime (second seed, Canada) is IN. World No. 4 and in fine form, the Canadian's serve-and-forehand game is tailor-made for fast grass. He was a Halle semi-finalist in 2021 and is a genuine title threat.
Ben Shelton (third seed, USA) is IN, making his Halle debut. The explosive lefty serve is perfect for these courts, and he opens with a blockbuster against wildcard Nick Kyrgios, a 2022 Halle semi-finalist.
Daniil Medvedev (fourth seed, Russia) is IN. A two-time finalist (2022 and 2025) still chasing a first Halle title, his flat, low strike has always translated well to the surface.
Taylor Fritz (fifth seed) and Flavio Cobolli (sixth seed) are IN. Fritz is a Wimbledon semi-finalist and grass standout; Cobolli, the Roland Garros finalist, skipped Stuttgart but takes his place here on a career-best run.
Alexander Bublik (seventh seed, defending champion, Kazakhstan) is IN. The two-time champion (2023 and 2025) beat Medvedev in last year's final and is unpredictable and lethal on grass.
Andrey Rublev (eighth seed, Russia) is IN. A two-time Halle finalist (2021 and 2023) still seeking the title.
Karen Khachanov, Frances Tiafoe, Joao Fonseca and 2022 champion Hubert Hurkacz are IN, adding further firepower, with German wildcards Jan-Lennard Struff and Daniel Altmaier carrying extra home hopes alongside Zverev.

With three of the world's top five, the defending champion and multiple former Halle winners (Bublik and Hurkacz) all in the draw, this is one of the deepest ATP 500 fields of the year. Zverev arrives as the headline act, but Auger-Aliassime's form, Shelton's serve, Bublik's title defence and Medvedev's pedigree make for a genuinely open week.

Summary

The Terra Wortmann Open is the heavyweight of the grass-court warm-up season, an ATP 500 played on some of the fastest, truest grass on tour. The quick, low-bouncing courts and the climate-controlled comfort of the OWL Arena's retractable roof reward big serving, flat hitting and first-strike aggression, on a champions' list headed by Roger Federer's ten titles.

So, expect serve-dominated, high-quality tennis, with shotmakers and clean ball-strikers holding the edge over grinders. The field is loaded: a newly crowned Grand Slam champion returning at home in Zverev, a red-hot Auger-Aliassime, a debuting Shelton, a defending champion in Bublik and a clutch of past finalists.

Ready for the marquee week of the grass swing on the lightning-quick lawns of Halle, the final big test before Wimbledon? With Zverev chasing home glory, three top-five seeds in the draw and barely a soft landing anywhere, this should be one of the most competitive Terra Wortmann Opens in years. Let's see who handles the fast grass best and cashes in the fantasy points.

Did You Know?

The roof was ahead of its time. When it opened in 1993, the Halle venue (now the OWL Arena) was one of the first tennis stadiums in the world with a retractable roof, which is why the tournament almost never loses time to rain, even in a wet German June.

This is Federer country. Roger Federer won the title a record ten times between 2003 and 2019 and posted 69 match wins at the venue, more than double any other player. His final title in 2019, at the age of 37, also makes him the oldest champion in tournament history.
