Climate overview

Temperature

Monthly mean temperatures are highest in July / August at 20.0 °C and lowest in February at -6.2 °C. This marks a clear shift in the monthly averages over the year, but these figures are not daytime highs or lows, and individual days can differ from the monthly pattern. The unweighted mean of the monthly mean temperatures is 6.9 °C. It is a summary of the calendar-month averages rather than a day-weighted annual average, so it should not be read as a typical temperature for every visit or month.

Snow

Mean daily snowfall is highest in February at 17.47 mm/day. This is a mean amount, not a measure of snowy-day frequency, snow depth, or snow cover, so it cannot establish what conditions a visitor will encounter on a specific date. The unweighted mean of the monthly mean daily snowfall values is 5.48 mm/day. It summarizes the monthly averages but does not show how snowfall is distributed among days or indicate skiing conditions.

Rain

Mean daily rainfall is highest in June at 3.59 mm/day, and lowest in February at 1.05 mm/day. The lower monthly mean can be a useful consideration for visitors prioritising less average rainfall, while the higher one is a reason to be prepared for wet weather. Neither figure indicates how often rain falls, and these are daily means rather than monthly totals. The unweighted mean across the monthly mean daily rainfall values is 2.54 mm/day. It offers a broad summary, but does not describe the rainfall on a particular date or the frequency of rainy days.

Sunshine

Mean daily sunshine duration is highest in July at 10.73 hours/day and lowest in December at 3.31 hours/day. Visitors planning outdoor sightseeing around brighter average conditions may find the higher-sunshine month relevant; these duration averages do not represent day length or guarantee sunshine on a given day. The unweighted mean of the monthly mean daily sunshine durations is 7.24 hours/day, a broad reference across the calendar months rather than a prediction for any individual day.

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

For visitors prioritising cooler monthly mean conditions, February is the relevant option, with a monthly mean temperature of -6.2 °C; this is not a forecast of daytime temperatures, so plan for variation during a stay. Those prioritising lower average rainfall may consider February, when mean daily rainfall is 1.05 mm/day. By contrast, mean daily rainfall is highest in June at 3.59 mm/day, making rain-ready clothing a sensible preparation; neither average guarantees dry or wet days, or says how frequently rain occurs.

For outdoor plans shaped by average sunshine duration, July has the highest mean at 10.73 hours/day, while December has the lowest at 3.31 hours/day. These are daily duration averages, not day length or a promise of clear skies. Snowfall also has its highest mean daily amount in February at 17.47 mm/day; that value alone cannot tell you whether snow will be falling or lying on the ground during your visit.
