When Monsoon Season Starts in Colorado and How It Impacts Summer Weather

If Colorado feels stormier in the summer, you’re probably experiencing the annual monsoon season.

As summer heats up, weather patterns shift — bringing more clouds, frequent storms, and afternoon downpours. This is the hallmark of the monsoon, a seasonal change in wind patterns that pulls moisture from the Pacific Ocean and California into the Southwest, including Colorado.

When Does Monsoon Season Begin in Colorado?
While monsoon season officially starts in mid-June, its full impact usually isn’t felt until July and lasts through August, according to the Colorado Climate Center. The moisture-laden system typically moves through Arizona and New Mexico before reaching Colorado.

Although the extra rainfall is often welcome, it can also bring some surprising side effects.

Monsoon Migraines Are Real
If headaches have been more frequent lately, the weather could be the culprit. Many Coloradans report migraines during monsoon season, often linked to changes in barometric pressure.

Doctors note that incoming storms can trigger symptoms like sinus pain, eye pressure, and what feels like a sinus infection — but is actually a migraine brought on by shifting weather conditions. So if you feel off when the clouds gather, you’re not imagining it.
