Actual monthly averages from the last 3 years (Open-Meteo). Real race day may vary.
Water temp uses athlete-reported values first, then official race data, then the marine archive (sea swims, measured at the nearest offshore point). Values tagged est. are modelled from recent air temperature for lakes and rivers, where no observational data exists.
