Why this date

Requests for this date frequently ask for the overnight readings alongside the afternoon peak. The hourly series reports both, so the overnight minimum and the hours spent above any chosen threshold can be read directly rather than inferred from a daily high.

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.
