Historical weather data, all-time temperature records, and monthly climate averages for Saint Paul, MN. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
April 5th in Saint Paul is classic transition-season roulette — the average high of 51° feels promising, but this date has swung from a scorching 86° in 2021 to a brutal 11° low in 2018. The good news: snow is essentially off the table, and there's only a 20% chance you'll need an umbrella.
Saint Paul doesn't mess around at the extremes — a 104° August scorcher in 1947 and a -32° January nightmare in 1951 represent a 136-degree spread that tells you everything about Minnesota's reputation. The wettest single day on record dropped 5.57 inches in May 1942, nearly matching a snowstorm in March 1952 that buried the city under 11.9 inches.
Summer is the clear sweet spot, with highs peaking around 84° the first week of July and the warmest stretch running through August. If you're cold-averse, avoid mid-January when average highs barely crack 23°. June through early July is the wettest period, so pack accordingly if you're visiting for the outdoor festival season.
