BLS metro-level wage data places Hydrologists pay in Phoenix-Mesa-Chandler, AZ at a median of $90,000 per year ($43.27/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $96,600, Phoenix-Mesa-Chandler pays 7% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 260 hydrologistss are employed across the Phoenix-Mesa-Chandler MSA in SOC 19-2043.

The Phoenix-Mesa-Chandler pay distribution spans from $70,000 at the 10th percentile to $173,470 at the 90th — a 2.5× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $75,810 and the 75th at $120,520, so half of Phoenix-Mesa-Chandler-based hydrologistss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Phoenix-Mesa-Chandler, AZ covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide AZ data, and peer-metro comparisons — a median is a starting point, not a ceiling.
