I don't see much on this board about storms as a potential cause of CHs.
I for one have experienced several CHs when there are storm clouds lingering in the area for days on end.

Has anyone else experienced this?

geo, I have been a CH for 12 years and for me high humidity for a sustained period will in my opinion cause me to go into cycle.  I also think this may be true with sudden changes in the barometric pressure.  When in cycle stale, stagnant air will trigger a hit.  The most significant evidence was I had been headache free for 6 mos and my son got married on Peter Island which probably was 98% relative humidity.  While sitting in the plane on the tarmac in Puerto Rica waiting to take off I got hit, unfortunately an 8, no meds no O2.  They almost made me get off the plane.  My only explantion was the humidity.  Don't know if this idea is just in my head (no pun intended) or factual but this is what I have observed over the years.

It's easy to understand why this is a recurring question but the medical research has consistently failed to turn up any factors. Migraine research has identified some evidence of triggers.

Don't jump re. alcohol! It's a clear trigger WHEN WE ARE IN AN ACTIVE CYCLE but that's a different animal from CAUSING a cycle to start.

Obstructive sleep apnea and cluster headache.

A patient with cluster headache often wakes from sleep. The relationship to sleep apnea has been described. This study sought to confirm the relationship cluster may have with sleep apnea. METHODS: Thirty-nine consecutive patients diagnosed with episodic cluster headache according to the International Headache Society (IHS) criteria were sent for polysomnographic studies. All patients were in an active phase when they were in the study. Patients were told of the proposed relationship and were allowed to choose a sleep laboratory close to their home. RESULTS: Thirty-one patients with episodic cluster headache completed an overnight polysomnographic study. Twenty-three were male and eight female. The average age was 51 years (range 33 to 78 years). The average weight was 173 pounds (range 117 to 260 pounds). A total of 80.64% had sleep apnea (25/31). Average respiratory depression index (RDI) was 19.0 (SD 14.6) with 6 patients having no apnea, 10 having mild, 11 having moderate, and 4 having severe apnea (RDI < 5 = none; RDI 5 to 20 mild; RDI 20 to 40 moderate; RDI > 40 severe). Oxygen saturation decreased on average to 88.4% SD 4.5. Sleep efficiency was 76.2% (SD 13.4). CONCLUSIONS: The data closely approximate those of Chervin et al, where 80% had RDI > 5.

THE RELATIONSHIP SLEEP APNEA HAS IN THE PERPETUATION OR PRECIPITATION OF CLUSTER HEADACHE IS STILL TO BE DETERMINED. THERE ARE SOME REPORTS THAT TREATMENT STOPS THE CLUSTER BUT THERE IS NO PROSPECTIVE STUDY. THE HIGH INCIDENCE (80.64%) SEEN IN THIS POPULATION SUGGESTS THE CLUSTER PATIENT SHOULD RECEIVE A SLEEP EVALUATION AND PERHAPS INTERVENTION WITH CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP) OR AN APPROPRIATE DENTAL DEVICE.

If there is a storm brewing or a snow storm a comming I am in a kip 10 guarenteed.  The change in barometric pressure has something to do with it.  I have also recorded high humidity to be a trigger.  I charted my hits and frequency and intensity for a couple of years in relation to weather and definetly found a link for me.  I would be able to tell the weather just by my head and how misserable I felt.  Then I would listen to a weather forcast and be correct as far as when it was going to rain or snow.

Yup...rapid changes in the barometer, for me...bam, bam bam...

I have found that prolonged cloudy or rainy days give me a rest. the pressure plays NO role whatsoever. I have been accused of being part vampire, but sunny days and me just dont get along. give me an overcast chilly day anytime!!!!!!!!!!!!   Tuck

Stormy weather - oh yes - as someone else said it is the change in the barometric pressure - or in Wisconsin we just call it a low front coming through which can last for days on end with high humidity.  Certainly gives me a headache!  Also - the going in and out of air-conditioning triggers CH for me as well.

When in cycle i get hit more when its raining or cloudy and they are harder to abort just like today also if i am out in heavy wind i will get shadows then when i enter a warm house i get hit.

bring on the sun is what i say
