The best time to visit Sanjo is during spring (April to May) or autumn (October to November) for pleasant weather and fewer crowds.Spring in Sanjo offers comfortable temperatures, typically ranging from 10°C to 20°C, making it ideal for exploring the city's outdoor attractions. You'll also have the chance to see cherry blossoms in late April, particularly beautiful along the Igarashi River. This season is superb for couples looking for scenic walks and comfortable sightseeing without the intense summer heat or winter cold.Autumn provides similarly mild weather, with temperatures between 10°C and 18°C, and the added beauty of changing leaves, especially around Yahiko Park, which is a short train ride away. This period is also well-suited for solo travellers interested in visiting local workshops and museums, as the cooler air makes it pleasant for walking between different venues. The Sanjo Kaji Matsuri (Blacksmiths' Festival) often takes place in early October, offering a unique cultural experience.While summer (June to September) is warm and humid, with temperatures often exceeding 25°C, it's a good time to visit if you're interested in outdoor activities like hiking in the nearby mountains.
