I don't have access to real-time data, so I can't provide the current weather conditions for San Francisco.

For the most accurate and up-to-date forecast, I recommend checking one of the following sources:
*   **The National Weather Service** (weather.gov)
*   **Weather.com**
*   **A weather app** on your phone or computer
*   **Search "San Francisco weather"** in your browser

San Francisco is also known for its microclimates, meaning weather can vary significantly even within a few blocks, and it often experiences fog, especially in the summer months.
