Forecast

Weather in Rancho Cucamonga is affected by changes in air masses and fronts that bring changes in barometric pressure. Pressure drops when storms come and rises when they leave.

Rancho Cucamonga's 1,800-foot elevation makes it harder for air to reach from the coast, which affects atmospheric pressure. The surrounding San Gabriel Mountains block some air flows, causing pressure differences.

Winter months have lower pressure due to storms, while summer months have higher pressure due to high-pressure systems. Spring and fall have moderate pressure.

Rancho Cucamonga has a Mediterranean climate, which means mild winters and hot summers. This climate type causes pressure fluctuations, making weather forecasts important for outdoor activities.
