Spring in Paris—roughly late March through May—offers the city at its most enchanting. Cherry and magnolia blossoms frame the Eiffel Tower by early April, Luxembourg Gardens bursts into bloom, and café terraces reopen for the season. Temperatures hover between 10-20°C (50-68°F), perfect for full days of walking without the wilting heat of summer. Rain showers pass quickly, and the longer daylight hours (sunset by 9pm in May) mean extended golden hour for photography and leisurely evening strolls along the Seine.
Crowd levels remain civilized compared to the June-August peak—you'll still need advance tickets for major museums, but queues move faster and you won't be shoulder-to-shoulder in the Louvre's galleries. Easter week (dates vary) brings French school holidays and increased visitors, so consider timing around it if possible. May 1st is Labor Day (everything closes), and several other public holidays dot the month, but these rarely disrupt travel plans significantly.
Pack layers: mornings can be crisp, afternoons warm, and evenings cool down quickly. A light waterproof jacket handles spring showers without bulk. The city's cultural calendar fills with events—gallery openings in the Marais, wine tastings, early-season outdoor concerts—and restaurant terraces become the place to be. Book popular restaurants 2-4 weeks ahead, and secure timed-entry tickets for the Eiffel Tower, Sainte-Chapelle, and Versailles (if venturing out) as soon as your dates firm up.
