Rocky hill with monastery, southeast of Rome, Italy
Monte Cassino is a mountain in Italy. Its summit stands 520 m above sea level.
From the lowest point within 5 km (28 m), it rises 492 m. The steepest side is the east face: 26° on average over the first kilometre. In places the ground near the top reaches 36° — terrain for climbers, not walkers.
The nearest town is Cassino, 1 km away at 40 m: 480 m below the summit.
Scores
Two scores out of 10, built only from open data — every part is shown. They describe what the mountain offers, not how safe it is.
Hiking & mountaineering
5.5/10
Difficulty to the top
Hike
Most path sections around the top are T2 on the SAC hiking scale.
Indicative only — never a safety assessment. Conditions change: ask local guides and check the forecast.
Ski score
—
No ski runs within 12 km in OpenStreetMap.
Ski (where OpenStreetMap has skiing within 12 km): up to 4 points for the length of downhill runs (300 km or more = 4), 1.5 for the number of lifts (40+), 1.5 for the vertical between lift stations (1,500 m) and 3 for the snow season — a month counts when the estimated mean temperature at the height of the ski area is −1 °C or lower and snow falls or lies there (NASA POWER, 2001–2020). Hiking & mountaineering: up to 2.5 for waymarked routes and paths, 1.5 for huts, 2 for the ascent from the valley (2,000 m), 1.5 for prominence (3,000 m), 1.5 for the season (months with summit afternoons above −5 °C) and 1 for via ferratas, climbing and glaciers. OpenStreetMap is built by volunteers: where few things are mapped, a score can be lower than reality.

Snow
In a normal year there is no snow on this mountain, not even at the summit.
Estimate for a normal year: average temperature and precipitation from NASA POWER, carried to each height, in a simple model of snow building up and melting. In a given year snow can come earlier or stay longer. It does not replace the local snow and avalanche bulletin.
Summit weather
Not a forecast: long-term averages (1991–2020), carried up to the summit. The orange line is where an average afternoon reaches 0 °C; above the dashed blue line it freezes even at dawn.
On an average July afternoon the summit reaches about 31 °C; on January nights it falls to about 1 °C. Afternoons at the top are above freezing in every month of the average year. In July the 0 °C line climbs to about 5,350 m, above the summit: the top thaws on an average afternoon. Across the region, August is the driest month (24 mm) and November the wettest (124 mm).

Estimate: the NASA POWER climate of a ~55 km cell (average height 454 m), adjusted to the summit by −6.5 °C per 1,000 m. Rain, wet days and sunshine are those of the region. Mountain weather changes fast — always check a local forecast. ★ = mildest months at the top.
Relief
Two cuts through the summit, 16 km long, from the 30 m Copernicus elevation model. Heights drawn 4× taller than lengths, so the shape can be seen.
Average slope of the first kilometre from the summit. The orange petal is the steepest side.
