How Does Blaenavon’s Altitude Affect Conditions?
At over 340m above sea level, Blaenavon routinely records lower temperatures and more fog than nearby Abergavenny weather readings might suggest. Wind speeds are frequently 10–15 mph higher than in valley towns, so the feel‑like temperature can be 3–5°C colder. For updates, both BBC Weather Blaenavon and the Blaenavon weather Met Office page provide location‑specific data.
Does Blaenavon get snow often?
Yes—Blaenavon snow is common in winter due to its elevation. On average, 10–15 days per year see lying snow, compared to just 2–5 in Newport. Check the live forecast above for the latest snow risk.
Is Blaenavon windier than the valleys?
Yes. Exposed ridges around Blaenavon mean gusts are often 10–15 mph higher than in Abergavenny or Pontypool. Wind chill can make a 6°C day feel like 2°C, so wear a windproof layer.
