If you only eat one bagel today, this is the bagel.
Summary
The article introduces sf-microclimates, a free hyperlocal weather API that provides real-time weather data for 50 San Francisco neighborhoods. It aggregates data from 150+ outdoor sensors to address San Francisco's dramatic microclimate variations, where weather can differ significantly between neighborhoods just miles apart. The API requires no authentication key and is designed for integration with Claude Code, Clawdbot, and other applications. The project was built by Solo Founders to solve the problem of generic city-wide weather reports that don't reflect actual conditions in specific neighborhoods.
