Belluno rain radar covers a Dolomites mountain provincial capital on the Piave river, sitting at 350–400 m altitude with abundant rainfall in summer and autumn and a relatively dry winter. Hyperlocal radar over Belluno often diverges sharply from radar over the pre-Alpine foothill towns further south, like Vittorio Veneto and Bassano.
The mechanism is a true Alpine/Dolomite orographic effect — moist air forced up steep mountain terrain produces heavier rainfall than the pre-Alpine foothill towns, with precipitation generally decreasing further north and further from the sea within the Dolomites. Precipitation peaks around May–June, with monthly averages up to roughly 116 mm in parts of the surrounding Dolomites, and summer storms often arrive as afternoon or evening convective thunderstorms building off daytime mountain heating.
RainViewer shows live radar sourced from the Protezione Civile national network and ARPAV, updated every 5 minutes, with the alert mix here broader than in the plain cities — Protezione Civile issues regional Alpine-specific alerts covering avalanche, landslide and flash-flood risk alongside standard rain and storm warnings. Hyperlocal radar reveals whether a thunderstorm is building over the surrounding peaks before it drops into the Piave valley — detail a general Dolomites forecast cannot give.
a marked afternoon-thunderstorm peak, building off daytime mountain heating.
heavy snow at altitude, with the Dolomites' ski season running through this window and around 30 cm/year of snowfall in Belluno itself, on the valley floor rather than at altitude.
precipitation ramps up toward the May–June peak, with monthly averages reaching roughly 116 mm in parts of the surrounding Dolomites.
rain remains abundant, easing gradually toward the drier winter window; summer hiking and via ferrata season peaks June–September, while the ski season drives winter tourism to resorts accessible from Belluno.
Belluno sits on the Piave, a river with a major flood history across the wider Veneto region — the town's river levels respond quickly to Dolomite rainfall and snowmelt upstream.
landslide risk is elevated given Belluno's steep surrounding terrain, a standing concern across Belluno province, which contains 46% of the Dolomites' territory.
winter tourists heading to Dolomites ski resorts accessible from Belluno track radar for snow and avalanche-relevant alerts before mountain drives.
summer hikers on Belluno's via ferrata routes check radar for afternoon convective storms building off mountain heating.
light manufacturing in Belluno province, including eyewear roots near Agordo, depends on weather-stable outdoor logistics through the mountain valleys.
RainViewer draws radar data for Italy from the Dipartimento della Protezione Civile (Italian Civil Protection Department) national radar network, supplemented by regional radar systems from ARPA agencies including ARPA Veneto, ARPAE Emilia-Romagna, ARPA FVG, and ARPAL, updated every 5 minutes. Coverage spans the Italian mainland, Sicily, and Sardinia. The same map covers the surrounding Dolomites, Treviso, and the Piave valley downstream.
Hyperlocal radar shows live rain over Belluno and the surrounding Dolomites, sourced from Protezione Civile and ARPAV. Afternoon convective storms building off mountain heating show up before they drop into the Piave valley. Check the map before heading outdoors.
Summer afternoon thunderstorms build quickly off daytime mountain heating around Belluno, a direct risk on exposed via ferrata routes. Live radar shows whether a cell is forming over the peaks. Check again shortly before setting out.
Heavy rain, snow or fog on mountain roads accessible from Belluno can slow travel to the Dolomites' ski resorts. Radar shows conditions building over the surrounding peaks. Check timing before driving up.
Belluno sits on the Piave, a river with a major flood history across the wider Veneto region, and its river levels respond quickly to Dolomite rainfall and snowmelt upstream. Landslide risk is also elevated given the province's steep terrain. Radar helps track rain building in the mountains above the Piave valley.
Winter (December–March) is relatively dry despite heavy snow at altitude, while precipitation peaks around May–June. Summer brings a marked afternoon-thunderstorm pattern rather than steady rain. Check radar even on clear mornings before hiking.
Precipitation generally decreases further north and further from the sea within the Dolomites, so Belluno on the valley floor sees less than the high peaks around it. The town's true Alpine orographic effect also produces heavier rainfall than the pre-Alpine foothill towns further south. A single Veneto-wide forecast misses this altitude-driven gradient.
RainViewer's radar map for Belluno combines the Protezione Civile national network and ARPAV data, refreshing every 5 minutes. This tracks afternoon convective storms building over the Dolomites in near real time. Direction and speed are visible as the map updates.
RainViewer can send a rain alert before a storm reaches Belluno's town center or the surrounding ski and hiking routes. Alerts follow the same 5-minute radar refresh. Set a location to get notified ahead of the storm.
Hikers on Belluno's via ferrata routes know an afternoon thunderstorm can build over the peaks faster than a general Dolomites forecast catches up. A regional forecast covers the whole province for the day — it doesn't say whether that storm has dropped into the Piave valley yet.
RainViewer gives you a 2-hour forecast in 5-minute slices, rain alerts before a storm reaches a via ferrata route or a ski resort access road, direction arrows showing whether afternoon convective storms are building off the surrounding peaks, 48 hours of radar history to see how yesterday's mountain storm moved, and tracking for multiple locations — Belluno, the Piave valley, and nearby ski resorts — at once. A regional forecast says rain is possible over the Dolomites. Live hyperlocal radar shows the storm cell over the mountains right now.
