Lake Dief Houseboats

Local Weather

May to October weather for Sandy Shores on Lake Diefenbaker, Saskatchewan, in half-month steps (days 1–15 and 16 through the end of the month). Air, precipitation, and wet days use nearby Rock Point observations, about 27 km away (climate ID 4026847).

• Each tile is one half-month from May through October. Early is days 1–15. Late is day 16 through the end of the month. Every tile shows a value.
• Air temperature, precipitation, and wet-day percentage are 2021–2025 daily averages from Environment and Climate Change Canada, Rock Point (climate ID 4026847). High and low are the average of each year’s half-month mean, so each year counts equally. A year is included for a variable only when that half-month was observed on at least 80% of its days. Precipitation is the mean of each included year’s half-month total; missing days are not filled in. A wet day has at least 0.2 mm, among precipitation observations in the years included for that half-month. Days flagged missing are left out.
• Every half-month has observations on at least 80% of its days, so all five years are included. The largest gap in an included half-month is 1 day, in early July 2023.
• Precipitation is liquid equivalent (rain plus the water in any snow), in millimetres per half-month.
• Sunshine is not biweekly. The 1991–2020 normals do not publish bright sunshine. Each month’s existing normal is repeated on both of that month’s tiles. Those hours are 1981–2010 normals from Outlook PFRA (climate ID 4055736), about 27 km northeast on the east side of the lake, not a 2021–2025 average.
• 24 days in the included half-months are flagged as a trace (under 0.2 mm). A trace counts as dry and adds nothing to the half-month total.
• Tile temperatures are rounded to the nearest degree.
