Climate Chart of Surrey, Canada
Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023
For Surrey, Canada, the climate data cover 2013–2023. The monthly mean temperature ranges from December at 2.4 °C to August at 18.7 °C, giving a broad picture of changing conditions through the year rather than daytime highs. Rainfall and sunshine also vary by month, while the recorded snowfall figures describe daily averages, not how often snow falls. Together, these measures offer useful context for planning, but monthly averages cannot predict the weather on a particular visit.
Climate overview
Temperature
The warmest monthly mean is August at 18.7 °C, while the coolest is December at 2.4 °C. These are averages across each month, not daytime maximum temperatures, so they do not describe the full range visitors may encounter within a day. Across the calendar months, the unweighted mean of monthly means is 9.9 °C; it is not a day-weighted annual average.
Rain
Mean daily rainfall is lowest in July at 0.87 mm/day, and highest in November at 8.16 mm/day. The figures are daily means for those months, not monthly rainfall totals, and a lower average does not guarantee rain-free days or indicate how frequently rain occurs. The unweighted mean across monthly rainfall means is 4.05 mm/day, rather than a day-weighted annual average.
Sunshine
Mean daily sunshine reaches its highest level in July at 12.86 hours/day and its lowest in December at 3.14 hours/day. These are averages of sunshine duration, not measures of day length, and they cannot guarantee how much sun a particular day will bring. The unweighted mean of the monthly sunshine means is 7.79 hours/day.
Snow
The highest monthly mean daily snowfall is recorded in February at 5.69 mm/day. This daily average does not establish the number of snowy days, snow depth, snow cover, or skiing conditions. The unweighted mean across the monthly snowfall means is 1.41 mm/day; it is not a day-weighted annual average.
Best Travel Time Guide for Surrey, Canada: Ideal Seasons and Weather Insights
For visitors prioritising lower average rainfall, July is a conditional option, with mean daily rainfall of 0.87 mm/day. Rain preparation remains sensible: the highest monthly mean daily rainfall is in November at 8.16 mm/day, and these averages do not tell you whether rain will fall on a particular day or how often. They are useful for comparing monthly averages, not for promising dry weather. If cooler monthly mean temperatures are your priority, consider December, when the monthly mean is 2.4 °C; this is not a daytime high, so pack for variable conditions rather than treating it as a daily temperature forecast. For outdoor sightseeing and daylight planning, mean daily sunshine is highest in July at 12.86 hours/day and lowest in December at 3.14 hours/day. Sunshine duration is not day length, and these separate criteria do not establish one universally best time to visit.
Snowfall planning also needs caution: the highest monthly mean daily snowfall is 5.69 mm/day in February. That average alone does not indicate snowy-day frequency, snow cover or depth, and cannot establish whether conditions suit snow-based activities on your dates.
