Rimini sits on Italy’s Adriatic coast in the Emilia-Romagna region, with a humid subtropical climate (Köppen Cfa) that brings hot, sunny summers and cool, damp winters. The Adriatic Sea moderates temperatures year-round, keeping winters milder than inland cities like Bologna (just 120km northwest) and summers slightly cooler with afternoon sea breezes. Average annual rainfall is 750mm, concentrated in spring and autumn, while July is the driest month at just 40mm. The city enjoys around 2,150 sunshine hours per year, peaking in July with 300 hours. Sea temperatures range from 10degC (50degF) in February to 26degC (79degF) in August, with the water warm enough for swimming from late May through late September. Humidity averages 73% annually, highest in December (82%) and lowest in July (68%). See our best time to visit Rimini for seasonal planning.

Spring warms up steadily, with March starting at 14degC (57degF) and May reaching 22degC (72degF).

Beach establishments start reopening in mid-April but full service doesn’t begin until late May. Sea temperature in May reaches 18degC (64degF), swimmable for the brave but still chilly for most. The Rimini Marathon typically runs in late March or early April, and the city’s parks and the San Giuliano waterfront come alive with flowers. See our Rimini events and festivals for seasonal events.

Sea temperatures hit 25-26degC (77-79degF) in July and August, making the Adriatic genuinely warm. Humidity sits at 68-70%, lower than many Mediterranean destinations because of the afternoon sea breeze (the brezza di mare). The beach stretches for 15km with over 200 stabilimenti balneari (beach clubs) operating at full capacity. Book beach spots and hotels 3-4 weeks ahead for July and especially the Italian August holiday period (Ferragosto, August 15) when the entire country heads to the coast. Evenings are lively along the lungomare (seafront promenade) with temperatures staying around 22degC (72degF) at night. Pack light clothing, sunscreen SPF 50, and a light jacket for air-conditioned restaurants. See our Rimini neighborhoods guide for area overviews.
