Be prepared at all times
At 1019 metres the weather poses hazards seldom encountered at lower altitudes.
- Winds can come up fast, sometimes to gale speeds.
- Never leave a dome open unattended. Wind can also rotate closed domes.
- Don't leave doors and windows open unattended.
- It is wise to carry warmer clothing if possible when out for a walk.
- Cars should have antifreeze in the radiator whatever the season.
Snow and ice safety
Weather conditions can change rapidly on Mt John. Snow can accumulate quickly on access roads, particularly during cold, overcast weather, making travel to and from the observatory hazardous.
- Before planning fieldwork or excursions, check current weather forecasts and road conditions.
- Ice can form on sealed surfaces around the station, especially near building entrances and in shaded areas.
- Take extra care around the dormitory entrances, the southern exit of the 1-metre telescope building, and the garage side door, where icy patches can persist.
- During snowfall, help prevent ice from forming by clearing snow from paths and doorways before it is compacted by foot traffic.
- Suitable footwear, cautious movement, and regular attention to changing conditions will help ensure everyone's safety during visits.
