CLIMATOLOGY OF THE GREAT VALLEY.

RED BLUFF.

Data by Mr. MAURICE CONNELL, Observer, Weather Bureau.

Red Bluff is the county seat of Tehama County, at the northern end of the Sacramento Valley. The city is situated on the western bank of the Sacramento River, the average elevation above sea level being 309 feet, and is in latitude 40 10' north, longitude 122 14' west. The land slopes gently to the river, and within a radius of 5 miles the country is comparatively flat. The general movement of the air is from the north and northeast into the valley from the mountains on the north and east. During the summer months, however, there is a wellmarked southerly movement of the air, which is in part due to the strong westerly indraft through the Golden Gate and its subsequent deflection northward through the valley. The highest temperature recorded is 114 and the lowest 18. The average annual precipitation is 25.56 inches.
