When planning a trip to Stockton, it is important to consider the variable weather throughout the year. Regardless of the season, comfortable walking shoes will be your best companion for exploring the city. Since daytime and evening temperatures can differ significantly and the weather changes from season to season, we recommend layering your clothing.

During this time, you will need lightweight and breathable clothing made from natural fabrics, shorts, t-shirts, a sun hat, sunglasses, and, of course, sunscreen with a high SPF. Evenings are usually warm, but a light sweater or cardigan may come in handy as lows drop to 15-17°C.

The winter period, from December to February, brings cooler weather with average temperatures around 10-11°C and an increase in rainy days (averaging 6-10 per month, and up to 12 in March). Although total precipitation is low, pack warm items for this time of year: sweaters, fleeces, as well as a waterproof jacket or coat and an umbrella. During the transition seasons—spring (March-May) and autumn (September-November)—the weather can be changeable. Spring becomes warmer and drier, while autumn gradually cools down with a higher probability of rain, making layered clothing, including a light jacket and sweater, the most appropriate choice.
