Clothing planning bands use the calculated mean daily maximum (-1.45°C) and minimum (-5.65°C), rounded then expanded by 2°C each way. These are outfit prompts, not forecast limits or confidence intervals. Monthly values are calculated from NASA POWER MERRA-2 gridded daily data for 1991–2020 at the city coordinates. They represent a regional model cell, not a city weather station. Street shade, coastal exposure, elevation and urban warmth can differ. Climate averages do not predict an individual trip. Mean monthly precipitation is 64.67 mm, with 14.8 model days of at least 1 mm; precipitation includes water-equivalent snowfall. Complete daily records were checked before averaging all thirty years.
