Waymo hours: is Waymo 24/7, and does it run in the rain?

Short answer: yes, Waymo runs 24 hours a day, 7 days a week in every city where it's open, including late at night. The exception is bad weather: during severe storms, flood risk or heavy snow, Waymo can limit or pause rides, as it did in Atlanta, San Antonio, Dallas and Houston in May 2026.

Round-the-clock service is one of Waymo's biggest advantages over other robotaxis, which often stop at night. Here's what to expect at different times and in different weather. For the cities themselves, see Waymo cities.

Late-night rides

Waymo's sensors don't need daylight: lidar and radar work the same in the dark, and the cameras are built for low light. Some riders say they prefer a Waymo late at night because there's no stranger in the driver's seat. A few things to know:

• Prices can be higher on Friday and Saturday nights. See Waymo prices.
• Wait times can be longer in the small hours, when fewer cars are out.
• Rules don't change: no open alcohol, and the person who booked is responsible for guests. See Waymo rules.
• Help is available 24/7 from the Support button on the car's screen.

Rain and fog

Normal rain isn't a problem. Waymo's radar sees through rain and fog, and the newest cars have cleaning systems that keep camera lenses clear. Waymo says its cars in Miami handle sudden tropical downpours.

Storms and flooding

Flooded roads are a different story. In May 2026, an empty Waymo drove into a flooded street in Atlanta and was stuck for about an hour. Waymo then:

• paused service in Atlanta and San Antonio while it worked on a fix;
• paused Dallas and Houston as a precaution before forecast severe weather;
• shipped a fleet update that limits driving at times and places with higher flood risk.

Waymo uses National Weather Service alerts among other signals to prepare for bad weather. If a flash flood or severe storm warning is in effect, expect fewer cars or a pause, and have a plan B.

Snow

Denver is Waymo's first real snow city. Its Ojai vehicles have heated sensors and small wipers, and Waymo tested winter driving in the Sierra Nevada, Michigan and New York. It still sets limits for snow and follows official travel advisories. See Waymo Denver.
