What changes about the house
- Coldest month: it is warmer at the destination, though unusual cold can still occur.
- Cooling: hotter peaks make air conditioning or shading more important. Check attic insulation and window sealing so the house does not trap heat.
- Garden: frost-free season length and last-frost timing point in different directions. Compare both measures before choosing crops or planting dates.
