How weather affects psoriasis

Not every weather factor hits every condition the same way. These are the inputs our Psoriasis scoring model weighs most heavily — and in Sacramento (West Coast), they interact with the local climate pattern: Seattle, San Francisco, and Los Angeles — Pacific coast weather trends and body-forecast scores.

Humidity

30% of score

Low humidity dries skin and disrupts the skin barrier, triggering psoriasis flares; moderate humidity keeps plaques hydrated.

UV exposure

30% of score

Moderate UV exposure (especially UVB) is therapeutic for psoriasis, slowing keratinocyte proliferation, but sunburn can trigger the Koebner response.

Temperature

15% of score

Cold weather worsens psoriasis through skin drying and reduced UV exposure; warm weather generally improves symptoms.

Air quality

15% of score

Air pollutants can trigger oxidative stress in the skin and exacerbate inflammatory pathways involved in psoriasis.

Wind

10% of score

Wind accelerates skin moisture loss and can carry irritants that aggravate exposed psoriasis plaques.
