Rain in Andora: What You Need to Know
The Andora rain radar tracks one of the drier stretches of the western Riviera, at roughly 750–800 mm a year, with November the wettest month and July the driest. This hyperlocal radar view matters here because a coast-wide Liguria forecast cannot show how quickly the Merula torrent behind town concentrates runoff from the surrounding hills.
The mechanism is Gulf of Genoa cyclogenesis, though systems reaching Andora arrive more attenuated than at Genoa itself, further along the coast. Even so, the Merula valley behind the town gathers water fast from the coastal hills, and storms typically arrive from the S/SW. A regional forecast smooths over this local concentration effect entirely.
RainViewer shows exactly where rain is falling right now, refreshed every 5 minutes from the Protezione Civile national radar network. A live radar reveals the Merula catchment filling in real time while the beachfront still looks clear — the kind of local detail a daily forecast cannot deliver.

Why You Need a Rain Radar in Andora
Merula torrent flash floods.
The Merula torrent has a history of flash rises during intense autumn cloudbursts, a direct risk to the valley below the greenhouses and along the coastal path.
Coastal mareggiate.
Storm-driven mareggiate affect the marina and seafront, relevant for boat owners and anyone using the beach promenade.
Greenhouse operations.
Horticulture growers in the Merula valley need to know when rain or storm cells are approaching to protect flower and vegetable crops timed to the mild winter climate.
Cycle path and coastal walks.
Visitors using the coastal cycle path built on the former rail bed benefit from checking radar before setting out on a ride between Andora and neighboring towns.
Castello di Andora visits.
Cultural tourists visiting the medieval Castello di Andora can check for approaching rain before the walk up.
RainViewer Radar Coverage in Andora
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 shows Sanremo and Imperia along the western Riviera, so you can track a system moving down the coast toward Andora.
Andora Rain Radar: Frequently Asked Questions
- Is it raining in Andora right now?
Check the Andora hyperlocal radar for live rain over the Merula valley and coastline, tracked by the Protezione Civile national radar network. The map updates every 5 minutes, showing whether rain is over the beachfront or still building inland.
- Can I plan a beach day in Andora this week?
Open the radar before heading to the beach, since Andora's long dry summer season can still see occasional storm cells move through quickly. A same-day check is more reliable than a weekly outlook.
- Will rain affect my ride on the Andora cycle path?
Check the radar before setting out, since the coastal cycle path runs close to the Merula torrent mouth, which can rise quickly during intense rain. A live view shows whether a cell is active along the route.
- Does Andora flood?
The Merula torrent behind town has a history of flash rises during intense autumn cloudbursts, the primary local flood risk. Coastal mareggiate can also affect the marina and seafront during storm events.
- When is the best time to visit Andora for dry weather?
July is Andora's driest month, part of a long sunny summer season that supports the beach economy. Late autumn, especially November, brings the wettest weeks and the highest flash-flood risk on the Merula.
- Why does rain in Andora differ from Genoa further along the coast?
Gulf of Genoa cyclogenesis systems reaching Andora are more attenuated than those hitting Genoa directly, so Andora sees less annual rain overall. The Merula torrent valley behind town still concentrates hill runoff quickly regardless of the lighter regional totals.
- How often does the Andora radar update?
The Protezione Civile national radar network refreshes every 5 minutes, and RainViewer displays that data live. This lets you follow a storm's approach along the coast in near real time.
- Can I get a rain alert for Andora?
Yes — set a rain alert for Andora in RainViewer to get notified before a storm reaches the Merula valley or the beachfront. This is useful for greenhouse growers and beach-day planning alike.
Track Rain in Andora in Real Time
Andora's Merula torrent can rise fast when an autumn cloudburst hits the hills behind town, catching beachgoers and greenhouse growers off guard.
RainViewer's 2-hour forecast breaks the next two hours into 5-minute slices, so you see the rain building over the valley before it reaches the coast. Set a rain alert before a beach day or a walk to the Castello di Andora. Direction arrows show whether the storm is arriving from the S/SW Gulf of Genoa. Scroll back 48 hours of radar history to see how the last cloudburst moved through the Merula valley. Track Andora alongside Sanremo and Imperia in the same view.
A forecast says "dry with isolated showers." Hyperlocal radar shows the Merula rising right now, street by street, not coast-wide.
