Rain in Alghero: What You Need to Know
Alghero rain radar shows what a Sardinia-wide forecast misses: this NW-facing Catalan port catches more of the island's autumn-winter rain than most of Sardinia, and a hyperlocal radar view tracks exactly where it lands, from the old town walls to the low Fertilia plain.
The mechanism is exposure. Alghero faces the Sardinian Sea with little orographic blocking, so SW and W Atlantic fronts arrive directly off open water, giving the city some of the island's more reliable autumn-winter rain. That same open exposure means the low-lying Fertilia plain and Calich lagoon just north of town — shared with Alghero-Fertilia Airport — take on water fast during intense downpours.
Protezione Civile alerts for Sassari province cover Alghero, and RainViewer's radar shows live rain building offshore before it reaches the coast. A hyperlocal view answers what an island-wide forecast cannot: whether the Calich lagoon plain is about to flood while the old town stays dry.
Rain by Season in Alghero
Autumn-winter (Oct-Jan)
The wet season, with November-December the wettest months as Atlantic fronts arrive off open water.
Summer (Jun-Aug)
Essentially rainless — peak "Coral Riviera" beach and diving season around Le Bombarde and Maria Pia. Coral-harvesting heritage and the Catalan old town's summer tourist calendar both run through the dry stretch, giving Alghero a sharp split between wet winters and dry beach summers.
Why You Need a Rain Radar in Alghero
Alghero-Fertilia Airport (AHO) operations
— The airport sits on the reclaimed, low-elevation Calich lagoon plain just north of town, flood-exposed in intense autumn downpours. Travelers check the radar before heading to the terminal.
Coral jewellery workshops and fishing
— Alghero's coral craft industry and fishing fleet track live rain along the coast before heading out.
Diving and beach days at Le Bombarde and Maria Pia
— Visitors time beach trips around the dry summer stretch, checking the radar for the rare summer shower.
Driving the SS291 to Sassari
— The radar shows whether rain over the Fertilia plain will affect the SS291 route before departure.
Touring the 14th-century Catalan old town walls
— The historic core sits above the flood-prone plain, and the radar shows when it is safe to walk the walls even as the lagoon area floods.

Alghero Rain Radar: Frequently Asked Questions
- Is it raining in Alghero right now?
RainViewer's hyperlocal radar shows live rain over Alghero's old town and the Fertilia plain separately, refreshed every 5 minutes and backed by Protezione Civile data. Check the map before deciding where to head.
- Can I plan a beach day in Alghero today?
Check the live radar before a beach day at Le Bombarde or Maria Pia. Summer showers are rare but the radar confirms clear skies before you leave.
- Will rain affect my flight at Alghero-Fertilia Airport?
Look at the radar over the Calich lagoon plain before heading to the airport. The low-lying site floods faster than the rest of town during intense autumn downpours.
- Does Alghero flood?
Yes — the Fertilia plain and Calich lagoon area north of the city, shared with the airport, are flood-prone in intense autumn downpours, part of the same NW Sardinia storm exposure that produced flooding after Cyclone Cleopatra in 2013.
- When is the best time to visit Alghero?
June through August is essentially rainless, ideal for the Coral Riviera beaches and the old town without rain interruptions.
- Why does rain vary so much across Alghero?
The city faces the Sardinian Sea with little orographic blocking, so Atlantic fronts arrive directly, but the low Fertilia plain and Calich lagoon collect runoff faster than the elevated old town.
- How often does the live radar update?
RainViewer's radar draws from the Protezione Civile network covering Sassari province and updates every 5 minutes, tracking Atlantic fronts as they reach the coast.
- Can I get a rain alert for Alghero?
Yes — set a rain alert for Alghero's old town or the Fertilia airport area and RainViewer notifies you before rain arrives.
