02 Evidence passport
What this page can—and cannot—say.
- Evidence found
- All 12 monthly normals from NOAA station SFM00068816, with at least 11 usable 1991–2020 years in every month.
- Source coverage
- CAPE TOWN INTL is 24.7 km from the fixed Stellenbosch anchor and differs by 76 m in elevation. Evidence grade: limited.
- What this means
- The table is suitable for comparing broad monthly travel patterns at this regional base.
- What this does not mean
- It does not describe every vineyard, forecast your dates, measure heat stress or guarantee safe and comfortable travel.

BottlePicker is a related 37X service and may earn commission from retailer links. That does not affect Follow The Vines’ climate filters or region order.
Sources & method
NOAA GHCN-Daily provides station observations; GeoNames supplies the fixed regional anchor. The approved build turns the raw R2 holdings into this small, dated projection and deploys no raw archive.
Projection generated 2026-08-25. Publication rule: at least 10 usable years per month, within 100 km and 350 m elevation difference.
