Best spots for sunset & shade
Shade Strategy
Mid-May sun in Nantes: UV index ~5–6 (moderate). Not as intense as southern Spain but enough to burn, especially at midday (12:00–16:00).
Morning (08:00–11:00): Gentle light, great for outdoor markets and walking. South-facing café terraces are pleasant.
Midday (12:00–16:00): Seek shade. The covered Passage Pommeraye, Château des Ducs courtyard, or indoor museums (Musée d'Arts) are smart choices.
Late afternoon (16:00–19:00): Perfect outdoor time. Jardin des Plantes has dappled shade under mature trees.
Golden hour (20:00–21:30): The magic window. Head to the Loire riverfront, Île de Nantes, or Butte Sainte-Anne for the best light.
