Climate Chart of Niagara Falls, Canada

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures are highest in July at 22.4 °C, while the lowest monthly means are shared by January / February at -3.3 °C. These describe the average temperature for each month, not typical daytime highs, so they do not show the full range visitors may experience from day to day. The unweighted mean across the calendar months’ monthly mean temperatures is 9.6 °C; it is a summary of monthly averages rather than a day-weighted annual average.

Rain

Mean daily rainfall reaches its highest monthly average in June at 3.49 mm/day, and its lowest in January at 1.21 mm/day. These are daily mean amounts, not monthly totals, and the lower average does not guarantee rain-free days or indicate how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 2.41 mm/day; it should be read as a summary of those monthly averages, not as a day-weighted annual figure.

Sunshine

Mean daily sunshine duration is highest in July at 11.83 hours/day and lowest in December at 3.68 hours/day. These averages can help describe differences in available sunshine, but sunshine duration is not the same as day length.

Best Travel Time Guide for Niagara Falls, Canada: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, January / February is the relevant period to consider, with monthly mean temperatures of -3.3 °C. This is an average, not a promise about the temperature on any particular day, so check forecasts close to travel and pack for changing conditions. If lower average rainfall is your priority, January is the conditional option, with mean daily rainfall of 1.21 mm/day. It does not ensure dry weather or tell you how frequently rain falls, so rain-ready clothing remains sensible; for preparation, note that the highest monthly mean daily rainfall is in June at 3.49 mm/day.

For outdoor sightseeing planned around average sunshine, July has the highest mean daily sunshine duration at 11.83 hours/day, while December has the lowest at 3.68 hours/day. These figures can inform daylight outdoor planning, but they measure sunshine duration rather than day length and cannot guarantee clear skies; the sunshine, temperature and rainfall criteria point to different considerations rather than one universal best time to visit.
