April 5 in Parkland sits right in the heart of spring's transition — historically, highs have averaged 57° with lows around 38°. It's a coin flip for rain (48% chance), but you can leave the snow shovel in the garage. The range on this date has been wild though: a balmy 73° back in 1966 and a teeth-chattering 29° low in 1961.
Parkland's weather history has some real extremes bookending it — a scorching 99° in June 1955 and a brutal -5° in January 1950, just days after the town's snowiest single day ever dropped 8.4 inches. November 1962 holds the wettest day on record at nearly 3 inches of rain in a single day, which tracks for a place that earns its Pacific Northwest reputation in the fall.
Summer is the sweet spot here — the week of July 9–15 averages a comfortable 76° high, and June through September generally stays pleasant and relatively dry. Winters are mild but gray, with late January bottoming out around 43° for highs. If you want to dodge the rain, avoid mid-to-late November, when weekly precipitation averages 1.75 inches.
