November is a good time to check your weather station before winter brings the possibility of freezing nights, persistent rain and strong winds. Reliable local observations start with sensible sensor placement, regular checks and an understanding of what each reading can, and cannot, tell you.
Across many countries governments have been providing advice to be prepared and here in the UK they launched a 'Be Ready' household preparedness campaign on 22 October 2026, encouraging simple steps to prepare for disruption to everyday services. This independent Weather Spares guide focuses on the weather-monitoring side of winter preparation. It is not part of the government campaign, and no government endorsement of Weather Spares or the document featured is implied. Read the official Cabinet Office announcement for the wider preparedness advice.
Freezing conditions: watch the trend, not just one number
Keep an eye on how outdoor air temperature changes through the evening and overnight. An air-temperature reading is useful context, but it does not directly measure the temperature of your path, greenhouse glass or road surface. Ground frost can occur even when the air temperature remains above freezing, so a positive reading is not an assurance that surfaces are ice-free.
Position a temperature sensor away from heat escaping from buildings, direct artificial heat sources and surfaces that distort readings (Air Source Heat Pumps, Heating Flues etc). Allow good airflow and follow the manufacturer's mounting instructions. Keep a note of the sensor's height and surroundings so you can interpret its readings consistently.
The Ecowitt WS80 ultrasonic 6-in-1 sensor measures outdoor temperature and humidity alongside wind speed, wind direction, UV and light. It is a sensor array, not a complete standalone station: a suitable Ecowitt console or WiFi gateway is required and is not included.
Rain: keep the collector level and clear
Place a rain gauge on a stable, level mounting where buildings, trees and overhanging branches will not intercept rainfall or drip into the collector. Avoid nearby surfaces that can splash water into it. Wind can also cause rainfall to be under-recorded, so the highest, most exposed position is not automatically the best place for your rain gauge.
When conditions are safe, inspect the collector and debris filter for leaves and other obstructions. Follow the manual for cleaning and maintenance rather than making unapproved modifications.
The Ecowitt WH40H wireless self-emptying rain sensor records rainfall in 0.1 mm increments. It includes a heightened collection bucket, anti-bird spikes and a debris filter, and requires a suitable Ecowitt gateway or separately sold display. With a compatible WiFi console or gateway, you can review rainfall history and graphs online.
Be cautious with readings during snow, ice and thawing conditions. A blocked collector may not record precipitation as it falls, and melting snow can produce delayed readings. Do not interpret a zero reading during freezing weather as proof that no precipitation has fallen, or treat a later thaw-related increase as fresh rainfall without checking conditions.
Wind: exposure matters as much as the sensor
Buildings, fences and trees can shelter a wind sensor or create turbulence. Choose a secure position with the clearest practical airflow, follow the manufacturer's orientation and mounting instructions, and record nearby obstructions. Readings from a sheltered garden should be interpreted as local observations rather than assumed to match an exposed official observing site.
The WS80 measures wind using ultrasonic sensing and has no moving parts. Its specified wind-speed range is 0–40 m/s, approximately 0–89 mph, and its reported gust is the maximum over the previous 28 seconds. That measurement range is not a guarantee of storm survival or ice-free operation. Follow the manual for operating limits and any cold-weather requirements.
An integrated sensor array involves a siting compromise: an exposed position that helps wind measurement may not be ideal for representative near-ground temperature measurements. Choose the location around the observations that matter most to you and note the limitations.
A practical November check
- Confirm that each sensor is reporting to its compatible console or gateway before mounting it in its final position.
- Check batteries, mountings and the rain collector according to the relevant manual. The WS80 uses solar power with two AA backup batteries; the WH40H uses one AA battery. Batteries are not included with the WS80.
- Record mounting positions and obstructions, then review readings over several days for gaps or unexpected changes.
- Compare local observations with official forecasts and warnings. A home station supplements these services; it does not replace them or certify that travel or outdoor work is safe.
- Inspect equipment only when it is safe. Do not climb to adjust sensors during strong winds, icy conditions or a storm.
Choosing your winter sensors
For wind, temperature, humidity, UV and light observations, consider the Ecowitt WS80. For a separately positioned rainfall collector, consider the Ecowitt WH40H. Both were in stock when this guide was prepared on 8 November 2026 and are also available as part of the Ecowitt HP2553H weather station giving you everything you need.
A well-positioned, maintained sensor is more useful than an impressive-looking installation in the wrong place. Start with sound siting, understand winter limitations, and use your readings alongside official information.
