Proper Placement for Accurate Stratus Precision Rain Gauge Results

Where you place your Stratus® Professional Precision Rain Gauge is just as important as the gauge itself. Improper placement is the #1 cause of inaccurate rainfall readings. Follow these CoCoRaHS-approved guidelines to get the most accurate measurements possible.

Placement Rules

• Away from obstructions: Place the gauge at least twice the distance from any tree, building, or fence as the height of that obstruction
• Level ground: The gauge must be perfectly level for accurate readings
• Avoid splash zones: Keep away from hard surfaces like driveways or patios that cause rain splash-back
• Consistent location: Once placed, keep it in the same spot for consistent long-term data
• Open sky exposure: The gauge should have a clear view of the sky above — no overhanging branches or roof overhangs

Mounting Height

CoCoRaHS recommends mounting your gauge so the top of the outer cylinder is approximately 2 feet above the ground. This minimizes splash-back while keeping it accessible for daily readings.

Secure Your Gauge Post Without Digging

Need a stable post for your Stratus® Professional Precision Rain Gauge? Stake It™ No-Dig Ground Anchor lets you secure a post firmly in any ground — no digging, no concrete, no tools required. Made in the USA.

Winter Placement Tips

For snow measurement, keep the gauge in the same location year-round. Use the liquid equivalent method for snow — bring the gauge inside to melt the snow before reading. See our complete winter measurement guide for full CoCoRaHS snow protocols.

Keep Your Measuring Tube Clear

If the inner measuring tube becomes scratched, cracked, or cloudy, replace it to maintain 0.01" reading accuracy.
