Rain in Biarritz: What You Need to Know
Biarritz occupies Atlantic coastal lowland and Pyrenean foothills, with the Garonne and Atlantic tributaries as the dominant hydrological feature. When rain falls upstream, the live radar shows whether it's heading toward Biarritz before any forecast updates.
A standard weather app gives Biarritz a single data point. The hyperlocal radar shows whether the rain is north or south of the Garonne and Atlantic tributaries, arriving fast or already clearing.
The Biarritz rain radar in RainViewer runs on Météo-France ARAMIS data — 31 dual-polarization Doppler stations with 5-minute scan cycles. Every pixel on the map represents actual radar returns, not interpolated estimates.

The radar shows whether rain will reach the Garonne and Atlantic tributaries catchment before your session ends or has already cleared the area.

RainViewer Radar Coverage in Biarritz
Rain data for Biarritz, France comes from Météo-France — the French national meteorological service — via its ARAMIS radar network of 31 Doppler stations covering metropolitan France. Most stations operate in dual-polarization mode, meaning the radar returns are processed for both liquid and frozen precipitation and deliver more accurate rainfall estimates than single-polarization systems. Scans update every 5 minutes and are processed into the ARAMIS mosaic within seconds of each scan cycle — no smoothing, no averaging delay. From Biarritz's position on the map, the radar composite shows coverage across the surrounding region continuously, including neighboring departments and cross-border coverage where relevant.

The Atlantic coastal lowland and Pyrenean foothills and Garonne and Atlantic tributaries drainage mean conditions can shift between forecast updates. Météo-France's dual-polarization ARAMIS network updates RainViewer every 5 minutes with exact rain position.
- Will it rain during a visit in Biarritz today?
Nouvelle-Aquitaine's rain patterns mean even forecast-clear days carry risk in Biarritz. Check the radar 20–30 minutes before a visit — it shows whether the approaching cell will arrive or track away, which a forecast cannot reliably answer at city level.
- Does rain affect local roads and motorway access?

Garonne riverine and tidal-marine flooding risk in Biarritz and Nouvelle-Aquitaine depends on proximity to the Garonne and Atlantic tributaries and low-lying terrain. The live radar shows whether upstream rainfall is still feeding the catchment — critical for knowing whether conditions will continue to worsen or have peaked.
