Bonadelle Ranchos and Madera Ranchos are a pair of communities in Madera County, California, United States. They are part of the Madera–Chowchilla Metropolitan Statistical Area. Prior to 2020, the communities were part of the Bonadelle Ranchos-Madera Ranchos Census Designated Place, with a population of 8,569 at the 2010 census. For the 2020 census, the area was split into two CDPs, Bonadelle Ranchos and Madera Ranchos.

The Bonadelle Ranchos-Madera Ranchos community is located at 36°56′11″N 119°53′12″W / 36.93639°N 119.88667°W / 36.93639; -119.88667 (36.936378, -119.886723).

According to the United States Census Bureau, in 2010 the CDP had a total area of 11.6 square miles (30 km), all of it land.

The Bonadelle Ranchos is often regarded as a Valley-Foothill transitional zone, because its elevation is higher than average for valley but slightly too low to be considered part of the Sierra foothills. About 7 miles (11 km) to the northeast lie the rugged foothills of the Sierra Nevada range. Its environment corresponds, showing qualities of a transition zone. The northeast portion of the area is the highest in elevation, and small tabletop hills are present: most notably Adobe Hill, with an elevation of 640 feet (200 m). Throughout the area there are large, rolling hills. Multiple creeks run through the area, but none are large enough to bring constant flow. The creeks include Little Dry Creek, Bonadelle Creek, Cottonwood Creek, and Root Creek. Many of these waterways flow in the winter months, when rainfall and snow filter down from the nearby foothills. There are many seasonal ponds in the area, but most are too small and short-lived to offer recreational activities. Much of the wildlife is typical for this type of environment. Mammals include foxes, ground squirrels, coyotes, raccoons, skunks and occasionally bobcats and mountain lions. Dove, crows, ravens, ducks, Scrub jays, California woodpeckers, egrets, red tailed hawks, turkey vultures, and geese can be found as well.

The climate in this area is noticeably different than the nearby cities, often 3 to 10 °F (2 to 6 °C) cooler during the winter months. Because of the openness of the surrounding areas, wind and storm systems can often become a temperature factor.

The climate in the area varies drastically throughout the year. Spring in the area is warm and mild, starting in March and ending in May. Temperatures generally reach the high 60s (in March). April-Mays highs reach the 70s and 80s, and nightly lows can still be in the mid 30s (in April), although the average low is 45 to 50 °F (7 to 10 °C). Many trees often begin to bloom as early as March.

Summer in the area is very hot and starts in June, lasting until early October. Temperatures regularly exceed 100 °F (38 °C). Sun is constant with essentially no clouds. Nightly lows in the area generally are in the high 50s and 60s, although some extremes have even reached the high 40s. Because of the virtual absence of rainfall, drought is constant through summer, and the risk of fire is high.

Fall in the area is mild, with highs in the 60s and 70s (°F), although some late fall patterns have highs still in the 80s. Fall is usually short lived, only encompassing mid-October until the end of November. That is typically when winter weather starts to move in. Nightly lows can greatly vary this time of year. Lows are generally 35 to 50 °F (2 to 10 °C), but in some cases can reach as low as 32 °F (0 °C).

Winters are generally mild, although variances can occur. The area experiences thick Tule fog, which is extremely dense fog that limits visibility to 500 feet (150 m) in some cases. Tule fog can last all day, although this is not a very common occurrence. The area experiences rain from November to March. Snow is never present in any measurable amount, but in some cases precipitation and temperature can coincide and bring flurries. They are short and nearly impactless. Winter lows can dip down quite low for California standards, as lows have been known to drop down to the high teens and 20s, although most winter lows are in the 30s and frost is quite prevalent. Highs in winter are in the 40s–50s, and most days are sunny with high-altitude clouds. Very windy days are present every winter, and these patterns may last for weeks at a time.

The Bonadelle Ranchos has a relatively long history, but not much is known about it. John Bonadelle, the founder of the area, was a landowner and owned most of the properties in the area. Many of the streets were named by him. Street names were often sold to people in Hollywood, who sometimes named them after themselves. Settlement began as early as 1940, but the movement trend boomed in the 1970s and continued on.

Bonadelle originally purchased the land from one of the three Smith family siblings that split the land into thirds once their father had passed. Currently, Kirby Smith still owns a comparable amount of land to the Bonadelle Ranchoes, which lies to the east and continues until Highway 41.
