- Northern summers run late June to late September; Southern late December to late March.
- Astronomical definition: Northern summers longer by about 4.5 days than Southern.
- Meteorological definition: Northern summers longer by about two days in non-leap years.
- Higher Northern heat is due to more land, less water, and cross-equatorial currents.
