Frequently asked questions
What is the barometric pressure in Manchester today?
On Thursday, November 12, barometric pressure in Manchester, New Hampshire is forecast to range from 1002 hPa (29.59 inHg) to 1011 hPa (29.85 inHg). Zutsu Note rates today's pressure in New Hampshire as Caution, based on the day's lowest pressure and the biggest change within 6 hours.
Will the barometric pressure change much in Manchester today?
Somewhat. Pressure in Manchester is forecast to fall by up to 4 hPa (0.12 inHg) within 6 hours today. A change this size is rated Mild on this page. Over the whole day, pressure falls by up to 9 hPa (0.27 inHg) and rises by up to 1 hPa (0.03 inHg).
Can a drop in barometric pressure cause a headache?
In some people, yes. In studies, about half of people with migraine say weather is one of their triggers. The exact mechanism isn't known. One leading idea is that the inner ear senses the change in pressure and the autonomic nervous system responds. Sensitivity varies a lot: the same weather change can bring on a headache in one person and not in another.
How can I tell if pressure changes trigger my headaches?
Keep a headache diary for 1 to 2 months and compare it with the pressure on each day. Zutsu Note, a free headache diary app built by a headache specialist, puts your logs and the pressure on the same chart automatically and shows the hourly pressure forecast for where you are, up to a week ahead. If your headaches keep coming back, get worse, or feel different from usual, talk to your doctor.
