When looking at San Francisco, our climate diagrams show an average precipitation of 104 mm of precipitation in January.
This year, however, the storm brought large precipitation sums. In the first third of January, there was already 157.3 mm of precipitation, significantly higher than the typical local climate. Our history+ data analysis tool or our weather archive enable a closer look at previous weather conditions on site.
This particular meteorological event can be well observed on the meteoblue weather radar. The high precipitation amounts, which are currently falling in California, are precisely displayed there. Furthermore, the dense rain cloud cover can also be seen on the satellite map.
Our weather maps also include historical satellite and radar images visible in a movie. The course of the extreme weather can be tracked precisely with the help of the animated weather radar. You can see how the rain masses approach the US west coast and move over California.

The unique movie function allows you to access recent cloud movements or precipitation events in the highest resolution. It is designed to detect real, local conditions and to track the current weather. Our weather radar covers each point on Earth and shows a detailed EU and US forecast. We invite you to test the movie function yourself by clicking on the arrow on the bottom right in the navigation.

The current weather pattern in California is the result of atmospheric rivers repeatedly hitting the mountainous California coast. Humid air masses from East Asia are carried to the west coast by a currently strong jet stream and develop into so-called atmospheric rivers, which are characterised by the transport of above-average humidity. The reason for this are cyclones over the Pacific, which form when cold and warm air collide. The rapid decrease in air pressure leads to strong wind speeds that drive the humid air masses from the east further towards the coast, collecting even more moisture on their way. Finally, the mountainous coast of California pushes the air masses to higher altitudes, where the moisture cools, condenses, and develops into heavy rainfall. Due to the long-lasting low-pressure areas over the Pacific and the persistent strong winds, more atmospheric rivers are to be expected, which will again bring heavy rainfall over California in the next few days. This can be also seen in our 14-Day Weather.
In addition, you can access radar and satellite data back to 2020 with our point+ subscription.You can test point+ for 14 days and experience it yourself!
With point+, you can activate the radar overlay on the satellite map and select your desired period in the past by clicking on the calendar icon in the bottom right-hand corner of the navigation bar.
