Note: to plot pressure along with actual headache data, go here
This page will plot out barometric pressure changes in a couple of different ways. It show recent pressure changes over the last few days, and can also show the historical pressure change variability over the course of quite a few years.
The recent change plot can help see whether a headache you're having now is possibly related to barometric pressure changes. The recent change plot shows the dips and rises in barometric pressure. Some people may find they have many of their headaches after a 0.20 inch or more decrease in barometric pressure.
The historical barometric change variability plot shows how often there is a day-to-day pressure change of 0.20 inches or more within each month. This is based on looking at data from 2007 to 2014 (if the airports you choose have data going back that far). This helps show what months may be particularly difficult for headaches in a particular area.
These plots are based on the use of airport weather data. Airports routinely have weather monitoring stations on-site, and they record and publish this data.
You can enter multiple airport codes. You have 3 lines in which you can enter codes. Youc an actually plot more airports than this at a time by entering multiple airport codes on individual entry fields, separated by spaces.
By entering multiple airport codes, you can compare barometric pressure variability in different regions and see if there might be an area that has less frequent and less severe barometric pressure changes that might bring headache relief, if you're someone that has such headaches.
Enter the airport codes of interest below. You can select multiple airports.
Note that ICAO airport codes seem to work best.
Some reference codes:
PHNL Honolulu (this is an ICAO airport code).
MSP Minneapolis/St. Paul MN - Works even through it is not ICAO.
KMSP Minneapolis/St. Paul MN - ICAO code.
ABQ Albequerque NM
KEUG Eugene, OR
Here are some places you can look to find airport codes.
