Limits of this record

These are hourly observations, not the day's certified extremes. A true peak can fall between scheduled readings, so a published daily maximum may differ from the highest value shown here.

This page reports a single station. A full report queries neighbouring stations for the same moment and prints each one separately, along with its distance and the offset between its observation time and the time requested.
