How Crowded Is Olympic National Park in March?

March runs about 0.5× Olympic National Park's average month, which makes it a very quiet month here — roughly 4% of the park's yearly visitors come in March.

In a typical March the park sees about 125,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 9th-busiest of the park's twelve months, sitting between the August peak (2.6×) and the December low (0.3×).

On our Best Time to Visit score March rates 51/100 ("Fair"), versus the top-rated May at 67/100 — best overall balance of crowds, weather and daylight.

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 50°F and an overnight low around 35°F, with about 6.9" of precipitation.

That average of about 42°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 50% of annual visitors, choosing March instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 11.6 hours of daylight in March to explore — between the 8.2-hour midwinter low and the 15.8-hour summer high.

Park-wide, 2025 drew 3,584,187 recreation visits, down 3.6% from 3,717,267 in 2024.
