Quarterly Climate Impacts and Outlook for the Western Region for June–August 2025. Dated September 2025.
Summer temperatures were above normal for most of the West except for isolated areas along the California coast, south central Nevada, and eastern New Mexico. Precipitation was below normal for most of the West, especially in coastal California and the Pacific Northwest. Monsoon season precipitation anomalies were mixed with below-normal totals for most of Arizona and western New Mexico, and above-normal totals for the rest of New Mexico.

Quarterly Climate Impacts and Outlook for the Western Region for March–May 2025. Dated June 2025.
Spring temperatures were near to above average for most of the West, with some pockets of below-average temperatures along the California coast and in other parts of the Southwest. In large swaths of the West, less than 70% of average precipitation was observed. Less than 50% of average precipitation was observed in parts of north-central California, southern Arizona, and southwest New Mexico.
