Nicolas Pereira has found hard courts difficult, recording 45–67 across 112 matches (40.2%). 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 (Australian Open & US Open): Nicolas Pereira has struggled at Grand Slam level on hard: 5–9 (35.7%) in 14 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Nicolas Pereira is 4–5 (44.4%) across 9 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

vs. Top 10 on hard: 3–5 (37.5%, 8 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 15–15 (50.0%); best-of-three: 30–52 (36.6%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 1988 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
