Daily Temperatures and Precipitation
The heatmap below color codes each day in a given row with a color corresponding to either the high temperature, low temperature, or precipitation in inches. Each row is a calendar year. Each column in each row is a day of the year. The higher density of dark red and orange cells in recent years shows the trend of hotter temperatures in the summer months in Sacramento. Select a tab to choose to display daily high temperatures, daily low temperatures, or daily precipitation totals. Hover your mouse over a cell for details (white cells = missing data).
