France Bordeaux Weather in September — Climate Guide
September in Bordeaux is very-high
September is very-high for Bordeaux.
September is arguably Bordeaux's finest month — warm days around 24°C/13°C (75°F/55°F), softening from the summer heat, with the wine country buzzing as the harvest (vendanges) begins. Rain returns a little (about 70mm), but plenty of sun remains.
The grape harvest gives the vineyards real energy — day trips to Saint-Émilion and the Médoc are special now, with the vines heavy and the cellars busy. It's a magical time for wine lovers.

Bordeaux in September — Full Picture
September is arguably Bordeaux's finest month — warm days around 24°C/13°C (75°F/55°F), softening from the summer heat, with the wine country buzzing as the harvest (vendanges) begins. Rain returns a little (about 70mm), but plenty of sun remains.
The grape harvest gives the vineyards real energy — day trips to Saint-Émilion and the Médoc are special now, with the vines heavy and the cellars busy. It's a magical time for wine lovers.
The summer crowds start to ease just slightly while the weather stays excellent for the UNESCO old town, the Cité du Vin, and the coast. Warm evenings keep the quaysides and terraces lively.
Note: it's still a popular month, so book ahead, especially for harvest-season château visits. Pack a light layer for cooler evenings and an umbrella for the odd shower. A top pick for weather, atmosphere, and wine.
What to Wear & What to Pack
Warm early autumn — around 24°C/13°C (75°F/55°F). Light clothing for the day with a light layer for cooler evenings. Sunglasses and SPF still useful; a folding umbrella for showers.
