Imperia works for most of the year thanks to a mild Mediterranean climate and a residents-first coastal look, so the best window depends on what you want. For swimming and full beach service, target late June through early September. For lower prices and quiet streets with still-warm days, go in May or late September. This guide breaks it down by month and links to the detailed Imperia weather by month data.
Best Time to Visit Imperia: Best Overall Weather
June and September are the sweet spots. June averages 24°C (75°F) by day with only 32 mm of rain and around 10 hours of sun, while the sea has warmed to 21°C (70°F) enough for swimming. September matches June on temperature with a warmer 23°C (73°F) sea and slightly more rain at 54 mm. July and August are hotter at 27°C (81°F) and 25°C (77°F) sea temperatures but draw the biggest crowds. If you want warm, dry, and less busy, book either side of the August peak.
Best Time to Visit Imperia: Fewest Crowds
Imperia is a working provincial capital, not a resort town, so it never feels as packed as Sanremo or Diano Marina. The quietest months with genuinely low visitor numbers are March, October, and November. October still reaches 21°C (69°F) by day for sunny coastal walks before the 86 mm of rain picks up. November is the calmest but also the wettest at 119 mm, though the Olioliva festival brings a lively few days to Oneglia that month. For solitude plus decent weather, pick October.
Best Time to Visit Imperia: Lowest Prices
Accommodation is cheapest from November through March, when most Riviera hotels shift to weekend-only or closed status and rates fall 30-50% below July levels. You will find four-star rooms like the Croce di Malta well under summer prices in February. Restaurants, museums, and the Museo dell Olivo (Olive Museum) stay open year-round, so a winter trip is entirely practical if you do not need beach time.

Best Time to Visit Imperia: Events and Festivals
The headline event is Olioliva, held in early November (usually 7-9 November) across the arcades and squares of Oneglia, celebrating the fresh Taggiasca olive oil. Summer brings the Calata G.B. Cuneo evening passeggiata, sailing regattas off Porto Maurizio, and open-air food stalls along the quays. Spring sees the flower nurseries open to buyers and a quieter cultural calendar. Time your visit around Olioliva if you care about local food. Our neighborhoods guide maps where each event sits.
Best Time to Visit Imperia: Months to Avoid
Avoid August if you dislike crowded beaches and peak prices, though Imperia stays calmer than neighboring resorts. Avoid November and parts of October if steady rainfall will derail outdoor plans, November averages 8 rainy days. July is fine weather-wise but rates spike. Winter (December-February) is mild but too cool for swimming, with the sea at 13-15°C (55-59°F). There is no truly bad month to visit, only months better matched to a swimming holiday versus a food and walking trip. Check Imperia travel tips and FAQ before you book.
