A temperature of 46 °C was recorded in Mostar.

Omissions

• The claim does not specify that the 46 °C figure refers to the all-time national record set on 31 July 1901, not to recent or current temperatures.
• The most recent data (2024–2025 heatwaves) shows Mostar peaks around 42–43 °C — e.g. 41.8 °C on 3 July 2025 and 'almost 43 °C' in 2025 — so 46 °C was not recorded in any recent summer.
• The evidence found consists of secondary news sources; no primary meteorological institute (e.g. Federal Hydrometeorological Institute of BiH) record was retrieved.
• The absolute record of 46.2 °C was measured in the shade of the meteorological station, a detail omitted by the MEP.
