Chiba Prefecture, located to the east of Tokyo and facing both the Pacific Ocean and Tokyo Bay, has a diverse coastline with varying water temperatures depending on the season. During the summer months, from June to August, the seawater temperature ranges from 77°F to 86°F (25°C to 30°C). These warm conditions make it perfect for a wide range of activities such as swimming, surfing, and beach sports, particularly at popular beaches like Kujukuri Beach and the coastal areas of Chiba City.

As autumn arrives, the temperature of the sea begins to cool gradually. In September and October, the seawater temperature remains comfortable, ranging from 70°F to 77°F (21°C to 25°C), which is still suitable for many outdoor activities. However, by November, the water temperature drops to between 59°F and 64°F (15°C to 18°C), which makes swimming less appealing for most people, although the cooler waters can still be enjoyed by those interested in more rugged outdoor activities like hiking along the coast.
