How and Where to Install Your Weather Station

Installing a personal weather station is one of the most rewarding ways to stay connected with your local conditions, track climate trends, and make informed decisions about gardening, farming, or outdoor activities. Proper installation is key to getting the most accuracy and reliability from your weather station.

The following guide explains how and where to install your outdoor sensors for the best results.

Choosing the Right Location

Selecting the right site is the most important step. The goal is to measure conditions that represent your general environment, not the influence of nearby structures or surfaces.

Pre-Installation

Before installing your weather station in its permanent location, we recommend operating the weather station for one week in a temporary location with easy access. This will allow you to check out all of the functions, ensure proper operation, and familiarise you with the weather station and calibration procedures. This will also allow you to test the wireless range – most modern weather stations use wireless radio frequency transmission between the sensor suite and the indoor console.

Site Survey

Perform a site survey before installing the weather station. Consider the following:

You will need to clean the rain gauge once per year and change the batteries every two years. Provide easy access to the weather station.

Avoid radiant heat transfer from buildings and structures - In general, install the outdoor sensor suite at least 15cm from any building, structure, ground, or roof top.

Avoid wind and rain obstructions - The rule of thumb is to install the outdoor sensor suite at least four times the distance of the height of the tallest obstruction. For example, if the building is 6m tall, install it 4 x 6m = 24m away. Nearby trees, chimneys and antennas that can also block or distort wind flow. 

Use common sense - if the weather station is installed next to a tall building, the wind and rain will not be accurate.

If the outdoor sensor suite is fitted with a solar panel, in New Zealand ensure the solar panel is facing north to ensure adequate sunlight exposure for consistent power.

Level surface - Use a spirit level to ensure the gauge is perfectly horizontal for accurate readings. ACCUR8 DWS weather stations have an in-built spirit level for this purpose.

Best Practices for Wireless Communication

Wireless range - The radio frequency communication between receiver and transmitter in an open field can reach its rated maximum distance only if there are no interfering obstacles such as buildings, trees, vehicles, or high voltage lines.

Wireless communication is susceptible to interference, distance, walls and metal barriers.

Radio interference from devices such as PCs, radios or TV sets can, in the worst case, entirely cut off radio communication. Please take this into consideration when choosing console or mounting locations. We recommend the following best practices for trouble free wireless communication.

Electro-Magnetic Interference (EMI) - Keep the console several feet away from computer monitors and TVs.

Radio Frequency Interference (RFI) - If you have other 433 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication.

Metal Barriers - Radio frequency will not pass through metal barriers such as aluminium siding. If you have metal siding, align the remote and console through a window to get a clear line of sight.

The following is a table of reception loss vs. the transmission medium. Each ‘wall’ or obstruction decreases the transmission range by the factor shown below.

Medium	Radio Frequency (RF) Signal Strength Reduction
Glass (untreated)	5-15%
Plastics	10-15%
Wood	10-40%
Brick	10-40%
Concrete	40-80%
Metal	90-100%

Temperature and Humidity Sensors 

Ideal placement - Over grass or natural ground, at least 1.2 to 1.5 metres above the surface.

Avoid - Concrete, asphalt, or decking, as these surfaces absorb and radiate heat, leading to false readings.

Shade and airflow - Ensure the sensors have good air circulation. Ideally temperature sensors should be shaded from direct sunlight. If it includes a radiation shield, it can handle more sun exposure, but still avoid placing it near walls or fences.

Mounting Options

Roof Mount

A roof mount provides excellent exposure for wind sensors but requires careful installation to avoid leaks or damage. Use a sturdy mast and ensure the sensor suite is secured against movement in strong winds.

Pole Mount

A pole in the garden or paddock is ideal for temperature, humidity, and rainfall sensors. Galvanised steel or aluminium poles resist corrosion and provide stability. Anchor the pole securely in concrete or with ground spikes.

Fence or Wall Mount

If space is limited, a fence or wall mount can work, but ensure the sensors are far enough from the structure to avoid heat reflection or wind interference.

Calibration and Maintenance

After installation, allow the sensors to stabilise for a few days, then compare readings with a trusted local source such as MetService or NIWA. Regular maintenance keeps data accurate:

Remove spider webs, leaves, or bird droppings from sensors.

Clean the rain gauge funnel and tipping mechanism annually (ACCUR8 DWS user manuals have instructions for how to do this).

Check mounting hardware annually for corrosion or looseness.

Making the Most of Local Conditions

New Zealand’s varied climate—from coastal breezes to alpine chill—means placement may need small adjustments. In coastal areas, corrosion-resistant materials are essential. In inland or rural regions, ensure the station is protected from livestock or machinery.

Final Thoughts

A well-installed weather station provides years of reliable data and a deeper understanding of local weather patterns. By choosing the right location, ensuring proper mounting, and maintaining the equipment, it’s possible to enjoy accurate, real-time insights into New Zealand’s ever-changing climate.
