Does the United States have a dry season in 2026?

California's classic pattern is wet winters and dry summers across much of the state. San Francisco, Los Angeles, San Diego, and the Central Valley all lean on cool-season Pacific storms for most annual rainfall, then bake through long summer drought months. Coastal fog can still cool afternoons near the ocean, but it does not replace winter rain totals. Inland valleys and Southern California basins feel the dryness as heat and brown hills. Compare neighbourhood microclimates in living in Los Angeles and living in San Francisco.

The Desert Southwest around Phoenix, Tucson, Las Vegas, and Albuquerque is dry for much of the year by definition: desert Southwest climate. Arizona and New Mexico add a North American monsoon window in mid-to-late summer, when thunderstorms can deliver a large share of annual rain in a few stormy weeks. That is a summer moisture pulse, not a tropical rainforest dry season. Las Vegas and much of the Mojave stay arid even when Arizona valleys storm. See living in Phoenix and living in Las Vegas for how that shapes housing and AC.

The Pacific Northwest, Midwest, Northeast, and humid South do not live by California's wet-winter / dry-summer script. Those regions still have dry spells, but movers should not import tropical or Mediterranean dry-season calendars wholesale: Rain in the United States.

Long dry summers dry fuels. California fire weather often peaks when vegetation is driest and offshore winds (Santa Ana or Diablo patterns) arrive before the first solid autumn rains. Smoke can reach mild coastal cities that never see the flame front. Plan indoor air habits with wildfire smoke and air quality, not only with sunshine and patio calendars.

Households should expect irrigation limits, drought-aware landscaping, and higher cooling demand through dry heat months. A dry climate does not cancel flood risk: hard ground and intense winter atmospheric-river rains can still overwhelm drainage after months without rain. Pair dry-season living with summer heat so you choose AC and shade for the months when rain stays scarce.
