Frequently asked questions
What is the barometric pressure in Greymouth today?
On Friday, 13 November, barometric pressure in Greymouth, West Coast is forecast to range from 1018 hPa to 1021 hPa. Zutsu Note rates today's pressure in West Coast as Stable, based on the day's lowest pressure and the biggest change within 6 hours.
Will the barometric pressure change much in Greymouth today?
Not much. The biggest change within 6 hours today is 2 hPa, below the 3 hPa that this page rates as Mild. Over the whole day, pressure falls by up to 1 hPa and rises by up to 3 hPa.
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 or GP.
The rating comes from the day's lowest pressure and the biggest change within 6 hours. It describes the weather, not your headache, and does not replace advice from your doctor. Forecast data: Open-Meteo.
