What changes about the house
- Coldest month: it is warmer at the destination, though unusual cold can still occur.
- Freezing months: there are fewer at the destination, though individual cold snaps 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: the frost-free season is longer or the last spring frost is earlier. Check both dates when planning crops and succession sowings.
