Hamilton, Canada

Hamilton sits under maritime skies in Canada, and the 2015–2024 weather record gives its sunshine a clear shape: the June peak reaches a 95/100 sun score, with daytime highs around 25°C — a solid base for a long-weekend city trip.

The year runs from average lows of -7°C in January to highs of 28°C in July. The wet–dry contrast is modest: 44% rain-day odds in April against 30% in March. Beach-warm afternoons (24°C and up) hold through June–August.

The seasonal arc is clear in the data: summer averages 26°C against winter's 2°C, while rain-day odds move from 35% in winter and 35% in spring to 36% in summer and 34% through autumn. Summer wins on the numbers and winter loses them; everything in between is a trade-off between warmth and crowds.
