What July feels like
July is the park at its peak, and the lower loop moves at the speed of whoever spotted a bison first. Thermal basins are best at first light, when the steam is thickest and the boardwalks are yours; storms build over the plateau most afternoons and clear off again.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
