The best time to go to Exeter, California, is during the spring (late March to May) and autumn (September to early November) months.During spring, the weather is pleasantly mild, with temperatures typically ranging from 15°C to 25°C. This period is ideal for exploring the local orchards and vineyards when they are in bloom, creating beautiful scenery. It's also a good time for outdoor activities like cycling or walking along the city's mural-lined streets without the intense summer heat.Autumn also offers comfortable temperatures, generally between 18°C and 28°C, and sees the area's harvest season in full swing. This is great for those interested in visiting local farms and markets, or taking scenic drives to see the changing colours of the surrounding foothills. The cooler evenings are also great for dining outdoors at one of Exeter's local eateries.While summer (June to August) brings very warm temperatures, often exceeding 35°C, it can still be a good time for travellers who enjoy hot weather and want to experience the vibrant agricultural scene at its peak.
