Plan around July
July is shoulder season: good weather, a step below the best months (April & May and September & October).
- Inside the wettest three-month stretch, June – August.
- Comfort slips from 75/100 in June to 67/100.
- Our Capital Cities Corridor route recommends Mar – Jun, so July falls outside its suggested window.
- Our Philadelphia, Longwood & Lancaster route is planned for Late Nov – Dec, a window set by the holiday season rather than the weather — July falls outside it.
