Thunder Bay, Canada
ocean climate · nature · low crowds · budget prices
Thunder Bay sits in an ocean-tempered climate in Canada, and the 2015–2024 weather record gives its sunshine a clear shape: the July peak reaches a 96/100 sun score, with daytime highs around 23°C — a solid base for a trip built around landscapes and trails.
July is the heat peak, averaging 23°C highs; January is the cool end, when nights dip to around -15°C. The wet–dry contrast is modest: 36% rain-day odds in April against 19% in March. Note that average highs never reach 24°C in any month — pack for mild weather rather than hot.
The seasonal arc is clear in the data: summer averages 21°C against winter's -5°C, while rain-day odds move from 25% in winter and 28% in spring to 33% in summer and 31% through autumn. Summer wins on the numbers and winter loses them; everything in between is a trade-off between warmth and crowds.
