My focus is identifying the optimal hour for a walk, specifically looking for periods of complete dryness and ample sunshine. **Selecting Best Hour** I've narrowed down the potential walk times to 12:00 and 13:00 based on dryness and calm wind criteria. Comparing sunshine, 12:00 offers slightly more, making it my current choice for the optimal walk. ```json {"hour": "12:00"} ``` {"hour": "12:00"}
