⚠️ Summer storms — short, sharp downpours can appear on humid afternoons.
July is peak season for the Seine quays and outdoor dining. Take advantage of the light for an evening visit to see the Cathédrale de Lumière, or head out to Giverny, where Monet's flower garden is at its most colourful with dahlias, roses and sunflowers in full bloom.
