What "oceanic / temperate" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Heidenheim an der Brenz's type — oceanic / temperate — sits in the broad family of mild, temperate climates.
Researchers write climate types as a short letter code. Here is what each letter means:

Heidenheim an der Brenz sits near a climate boundary
This city sits right on the line between oceanic / temperate and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has Heidenheim an der Brenz's climate type changed?
Stable — Heidenheim an der Brenz's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
Lawns and broadleaf trees thrive; heat-loving crops (tomatoes, peppers, melons) struggle without help. Famous for roses, leafy greens and apples.
Late spring through early autumn is the best window for outdoor travel. Winters are wet and grey but rarely brutally cold.
The 'comfortable' climate — no real extremes, but grey and damp through much of the year. Heating is needed in winter; AC is often unnecessary.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Heidenheim an der Brenz's measured 30-year climate normals (1991–2020) — the same official records behind Heidenheim an der Brenz's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Stotten, a weather station, about 21 km from the city centre. The underlying daily records come from NOAA's global station network.
