June is one of the best months to visit — and the month of the Armada. Here's what to expect and what to bring.
June in Rouen is mild and green, with daytime highs around 21–22°C and cool nights near 11–12°C. Normandy's weather is changeable, so expect a mix of sunshine and the occasional shower. Days are long — light lingers until around 10pm, perfect for the Cathédrale de Lumière after dark.
