Averages and Extremes Historical Data (text files) PlotsThe "current month" page has this month and previous months back to May 2008. A more detailed report in pdf format is prepared a few days after the end of the month. Because the data changes every day, refreshing/reloading the pages in your browser is advisable.
Daily data and the weather at a glance files have been updated now, after we recovered from a computer failure over the holiday break. We apologize for the inconvenience.
