When to Visit Lyon

Brings Lyon's coldest period in practice, with highs sitting around 7°C (44°F) and lows that frequently touch 1°C (33°F). The valley fog tends to be at its most persistent this month, sometimes lasting for most of the day, and the city takes on a quiet, slightly withdrawn character.

Is marginally warmer, with highs nudging toward 9°C (48°F), and it's the driest month of the year at around 41mm of rain. That said, 41mm in February still means regular grey days, and the fog remains a fixture. The city is at its emptiest, which has its own appeal in a place as historically layered as Lyon.

Signals the start of movement: highs reach 13°C (56°F) and the fog begins to lift more reliably by midday. Rainfall ticks up slightly to around 48mm but spring is visibly arriving, on the slopes of Croix-Rousse where the market gardens that fed the city for centuries start to green up.

Settles into spring properly, with highs of 17°C (63°F) and lows of 7°C (44°F). Rain picks up to around 69mm and tends to arrive as proper showers rather than grey drizzle, often followed by bright afternoons. This is when Lyon's outdoor café terraces start to fill and the Presqu'île becomes a pleasure to walk.

Is Lyon at close to its most appealing: highs of 21°C (70°F), long days, and the city in full spring mode. It's also the rainiest spring month at around 81mm, typically coming as afternoon or evening thunderstorms that clear quickly. The hills above the city are at their greenest.

Warms considerably, with highs of 25°C (78°F) and lows of 15°C (59°F), and rain settles back slightly to around 74mm. The Rhône and Saône quays come alive, and the city begins to adopt the relaxed pace of a French summer. Early June often has some of the best weather of the year before the full summer heat locks in.

Is peak summer in Lyon, with highs of 28°C (82°F) and lows of 17°C (62°F). The heat can feel intense in the valley, in the narrow streets of Vieux Lyon, and afternoon storms are possible even if rainfall (around 69mm) is no higher than spring. Many Lyonnais leave the city in August, making July the more locally animated of the two summer months.

Matches July's highs at 28°C (82°F), and the city empties noticeably as residents depart on holiday. Tourists fill the gap, in the old town, though the atmosphere can feel slightly suspended. Rainfall is around 66mm, often arriving as brief intense storms. The heat can be uncomfortable on hot days.

September is Lyon's transition month, and seasoned travelers treat it like a whispered secret. Highs ease to 23°C (73°F), warmth lingers, crowds melt away, and rainfall creeps back to 81 mm. Most showers arrive as evening drama, not all-day gloom. Terraces stay open. Harvest begins. Taste the new vintage.

October is Lyon's wettest month at 99 mm, and you feel the shift. Highs fall to 17°C (63°F), lows dip to 9°C (49°F), fog drifts in, and rain settles rather than storms. Yet the Croix-Rousse hillside and Parc de la Tête d'Or glow with autumn colour. Indoors, markets, bouchons, and covered passages reclaim centre stage.

November turns cold and wet. Highs hover at 11°C (52°F) and rain totals 86 mm. The city retreats indoors. Conversations turn to the Fête des Lumières in early December. Seek refuge in the covered Halles Paul Bocuse. Linger over long bouchon lunches.

December starts cold and stays cold. Highs reach 7°C (45°F), lows sink to 2°C (35°F). Then the Fête des Lumières ignites four nights around December 8th. Outside those dates, Lyon is quiet, softly festive, and charming for travellers who embrace the chill.
