San Francisco County
Switch hazards to redraw the map. Colors use one national scale (darker is higher), so you can compare this area to the rest of the country. Risk tiers are based on high-emissions projections that don't change with the scenario selector below.
Each county is shaded on a 1–10 dryness scale based on historical climate. Warmer colors = the visually drier end of the map: less moisture to start with.
Choose an emissions pathway and time window.
Everything below updates with the scenario you set here. Climate data is for representative ZIP 94112, not a city-wide average.
Seasonal peaks (hottest-month high and coldest-month low) compared to your selected scenario, with mean daily high and low by month below.
Monthly precipitation, baseline vs projected scenario. The wet and dry seasons are this location's wettest and driest six consecutive months; each row shows the season total with its per-month average, on the same scale as the chart below.
Combined heat and humidity (wet bulb) stress plus days reaching 90°F or warmer. Wet bulb is the temperature at which sweat stops cooling the body effectively.
Baseline and projected both show zero days in every month for this threshold and period.
The annual window between last spring frost and first fall frost, baseline vs projected scenario.
