Jaume Munar has found grass courts difficult, recording 6–14 across 20 matches (30.0%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Wimbledon): Jaume Munar is 5–6 (45.5%) across 11 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on grass — best-of-five: 5–6 (45.5%); best-of-three: 1–8 (11.1%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2025 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
