Do you think now is a good time to prepare your home for hotter summers?

Colorado has recorded above-average temperatures every month since February 2025, the last cooler-than-average month being January 2025. Five months in the tracked period were record-breaking statewide, with February, March, August and September 2026 among them.

Why it matters

The unbroken run of warm months, measured against statewide records dating to 1895, shows a sustained rather than isolated shift in conditions across the state. Continued above-average readings would extend a streak that already spans more than a year and a half.

Statewide monthly records show 5 record-breaking months since February 2025, measured against temperature data dating to 1895. The projected November 2026 result and whether the streak reaches January 2027 are not yet known.

The details

Every month from February 2025 through October 2026 ran hotter than the Colorado statewide average, with February, March, August and September 2026 setting records. July 2026 was the state's second-hottest month on record, and Denver recorded its warmest March and second-warmest July on record.

January 2025: Last cooler-than-average month statewide.
February 2025: Consecutive above-average months begin statewide.
February 2026: Record-breaking statewide, with Denver's third-warmest February.

Seasonal Patterns

Measured against statewide temperature records kept since 1895, the 2025–2026 run of above-average months stands out as a sustained departure from the historical average. It is reported here as a record-based comparison rather than a claim about a single cause.

Residents tracking daily heat should expect warm conditions to persist if the projected November 2026 above-average result holds. Planning around sustained above-average temperatures may matter for outdoor work, water use and heat safety.

The takeaway

A run of 21 consecutive above-average months is a measurable pattern worth watching month by month. Checking current statewide conditions helps readers see whether the streak continues into the coming winter.
