A video shared on X by William Justo captures a striking lightning display over San Jose during the North American monsoon season.

The footage reveals occasional lightning bolts illuminating the night sky above a residential neighborhood. Bright flashes sharply contrast with the surrounding darkness.

This display is part of the 2025 monsoon season, a period known for increased thunderstorm activity in the region, especially in late summer and early fall.

The lightning is fueled by moisture from the Gulf of California and the eastern Pacific, which helps trigger thunderstorms, particularly at higher elevations.

The timing of the video matches typical monsoon patterns, which can persist into September, according to weather forecasts for San Jose.
