Autumn can bring stronger winds, driving rain and falling leaves. If you rely on a wind sensor for weather monitoring a little maintenance before the first storm can help you spot problems while conditions are still safe.
Start with a visual inspection
From a safe position, check that the sensor and its mounting are secure, upright and free from damage. Look for loose brackets, cracked housings, corrosion and cables that have rubbed against an edge. If the sensor is mounted at height or near electrical equipment, leave a repair to a qualified professional.
Clear debris
Leaves, cobwebs and dirt can obstruct moving parts or cover sensing surfaces particularly on ultrasonic anemometers. Follow the manufacturer's cleaning instructions and use a soft cloth or brush where appropriate. Avoid pressure washers, harsh cleaners and forcing any part that does not move freely. For a traditional cup and vane sensor, check that it turns freely once clean; for other sensor types, follow the specific instructions for that model.
Check connections
If your sensor uses batteries, check their condition and replace them according to the manufacturer's guidance. Inspect accessible plugs and cable connections for moisture or wear, without opening sealed or mains-powered components. Confirm that the sensor is communicating with its display.
Test before bad weather arrives
Check your sensor on a dry day with a light breeze. Compare readings with a nearby trusted weather source as a rough check, bearing in mind that buildings, trees and mounting height can make local wind readings differ. A sensor that gives intermittent readings, fails a test or shows physical damage may need further maintenance or replacement.
After a storm
Once conditions are safe, check for shifted mounts, impact damage, water ingress and newly trapped debris. Do not try to resolve problems in wet or windy weather. Keep a note of recurring faults so you can identify patterns and share useful details with us.
A short pre-storm check is much easier than troubleshooting in the middle of a gale. Keep your sensor's model-specific manual handy, and make maintenance part of your regular autumn routine.
