Why Cold Weather Can Trigger Sinus Headaches (and How to Prevent Them)

When rain clouds roll into California, many people feel it in their heads before it hits the forecast. Changes in barometric pressure and colder, drier air can lead to sinus pressure, congestion, and headaches—especially in people with allergies or chronic sinus issues.

Why Weather Changes Affect Your Sinuses

When air pressure drops before storms, it can cause sinus cavities to expand slightly, leading to pain or pressure around your eyes, forehead, and cheeks. Cold, dry air also irritates nasal tissues, making them more prone to inflammation or infection.

Common California Triggers

Even mild California winters bring shifts in humidity, cooler nights, and indoor heating that dries the air. For many Bay Area residents, this combination means more sinus congestion and discomfort.

How to Prevent Sinus Pain This Season

  • Use a humidifier to add moisture indoors.
  • Stay hydrated to keep mucus thin.
  • Try saline nasal rinses to clear congestion.
  • Avoid sudden temperature changes when possible.
  • Manage allergies with over-the-counter antihistamines or nasal sprays.

If symptoms last more than 10 days or include fever or discolored mucus, see your BASS Primary Care or ENT specialist for evaluation.

Frequently Asked Questions:

Q1: Why do my sinuses hurt when it rains or gets cold?

Falling barometric pressure can cause sinus cavities to expand, leading to headaches or pressure. Cold air also dries out nasal passages, increasing irritation and inflammation.

Q2: What’s the best way to stop sinus headaches during winter?

Stay hydrated, use a humidifier, and rinse with saline to keep nasal passages moist. If symptoms persist, talk to a doctor—some people benefit from allergy or sinus medication.
