April 5 in Murrysville sits right in the heart of spring's unpredictability — over 80 years of data, highs on this date have swung from 73° as recently as 2023 to a stinging 26° low back in 2013. The average looks pleasant at 58°/37°, but a coin-flip 56% chance of rain means an umbrella is still a smart call.
Murrysville's weather has real range: the thermometer has hit 98° in July and bottomed out at -11° just this past January 2026. The wettest single day on record dumped 7.35 inches in September 2004, and a January 1966 snowstorm buried the area under 14 inches in one shot.
Summer is the sweet spot, with highs peaking around 85° the first week of July before gradually easing into a comfortable fall. If you're cold-averse, avoid mid-January when average highs scrape just 35°. The wettest stretch falls in mid-June, so early summer travel plans are worth watching.
