Fontainebleau Weather by Month: Temperatures, Rainfall and Sunshine

Fontainebleau sits 65 km southeast of Paris in the Seine-et-Marne department and shares the capital’s oceanic climate (Koppen Cfb): mild, wet winters and warm but rarely hot summers. The town’s famous forest, roughly 28,000 hectares of oak and pine, keeps summer afternoons a couple of degrees cooler than central Paris and makes winter walks muddy from November to March. Here is the best time to visit Fontainebleau and a month-by-month temperature and rainfall breakdown. Check the things to do in Fontainebleau for specifics.

Fontainebleau Weather in Winter (December to February)

January is the coldest month, averaging 5°C (41°F), with daytime highs of 7°C (45°F) and nights around 2°C (36°F). Rainfall runs 44 to 47 mm a month, and snow falls on only 2 to 3 days a year, so it rarely settles. The chateau runs on winter hours (9:30 to 17:00), and the forest paths stay open but get muddy, so bring waterproof boots if you plan to hike. The Fontainebleau travel tips covers this in more detail.

Fontainebleau Weather in Spring (March to May)

Spring warms quickly: March highs reach 12°C (54°F), April 16°C (61°F) and May 19°C (66°F). May is the wettest month of the year at 71 mm, often as short showers rather than all-day rain. The chateau gardens and the English garden bloom through April and May, which makes this one of the better times to visit before summer crowds arrive.

Fontainebleau Weather in Summer (June to August)

July is the warmest month, averaging 20°C (68°F) with highs of 26°C (79°F) and overnight lows of 14°C (57°F). June and August sit just below at 18°C and 19°C. Rainfall drops to 40 mm in July, though a short heatwave can push daytime highs past 35°C (95°F). The forest shade and the boulders stay a few degrees cooler, so climbers head out early and finish before midday. Read the Fontainebleau neighborhoods before you book.

September keeps highs near 21°C (70°F) and lows of 11°C (52°F), while October cools to 16°C (61°F) and November to 10°C (50°F). Rainfall returns in October and November at 54 mm and 53 mm.
