What the National Park Service says about the weather
Though the park shares a border with our southern neighbors, the elevation and the mountain ecosystem keep Coronado National Memorial relatively cool in the summer, and winter can bring snow. Summers are warm, with daytime temps in the 90s F (32-37 C) and low humidity in May, June, and July. The summer rainy season (monsoon) is between late June and early September. Monsoon thunderstorms can cause flash floods. Winter temps can fall below freezing at night, with highs 40-60 F (4-15 C).
