The ongoing
Super El Niño is anticipated to bring
cooler-than-average and wetter-than-average weather to both
Black Canyon of the Gunnison and Mesa Verde National Parks in April 2027. [

During historically strong El Niño events, the sub-tropical jet stream shifts south, funneling consistent storm tracks across the Four Corners region. This pattern will extend moisture well into the spring before the El Niño weakens later in 2027. [

Black Canyon of the Gunnison National Park
The park is positioned on the edge of the enhanced southern storm track, resulting in highly unpredictable spring conditions. [

- Temperature: Average daytime highs normally reach the mid-50s°F (13°C), but are anticipated to tilt cooler than normal. Nighttime lows frequently drop below freezing. [1]
- Precipitation: April is historically transitional, but expect above-average precipitation. Because of the elevation (around 8,000 feet at the South Rim), much of this enhanced moisture will manifest as heavy spring snowstorms rather than rain. [1]
- Park Impact: The high probability of lingering snow and ice means the scenic South Rim Drive beyond the visitor center may experience delayed openings. Inner canyon routes will remain highly hazardous, slick, and subject to winter-like conditions.
Mesa Verde National Park
Located further south in Colorado, Mesa Verde sits directly in the target zone for El Niño-fueled storm systems. [

- Temperature: Normal April highs sit near 60°F (16°C), but will likely track colder than average due to extensive cloud cover and persistent storms. [1]
- Precipitation: Expect a noticeably wetter-than-average month. While the valley floor and lower ruins may see heavy rain, the higher elevations of Chapin Mesa and Wetherill Mesa (over 7,000–8,500 feet) are prone to significant spring snowfall. [1, 2]
- Park Impact: Increased moisture and freeze-thaw cycles elevate the risk of rockfalls along the steep main park road. Ranger-guided cliff dwelling tours, which typically begin phase-ins in April, could face delays or cancellations due to icy or muddy trail conditions.
Historical Comparison
This setup mirrors past historic Super El Niño events, such as the springs of 1983, 1998, and 2016, which brought late-season mountain snowpacks and unseasonably damp springs to Southwest Colorado. [
