NOTE: The web page values are updated automatically from our service retrieving data from the HOBOlink service periodically. The HOBO weather station records every 2 min and automatically updates HOBOlink service approximately every 10 min. See the weather station HOBOlink web interface for the latest 10min values.
(*) Sunrise and sunset times are not obtained from the measurement station, but are calculated for the date of measurements by the web server using the station coordinates.

Last hour wind direction and speed graph up to 04:26
The concentric circles represent records of the last 60 min at 4 min intervals, with the latest value represented by the outer circle (hour 04:26). Dots between circles correspond to intermediate measurements at 2 min intervals. The vectorial mean wind direction for the last 60 min is presented by the ■■ radius with current value 21.8 ° (NNE - Greco-Tramontana). Only measurements with wind speed > 0.00 m/s are taken into account in the calculation The colour of the dots represents the wind speed in accordance with the colour code which follows.
