Weather in Eugene in March

United States · 20-year averages, March

A hard month. March asks something of you. Go in knowing what. You should expect rain on 19 days of the month, which is more days wet than dry.

March ranks 8 of 12 in Eugene: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 19 days, 6 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 12.5 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 3 nights fall below freezing. Across the twenty years measured, the hottest March day reached 26.1 °C and the coldest night fell to -4.2 °C, and the wettest single day dropped 44 mm — roughly 26% of the month's rain in one day.

March is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest March on record still delivered 362 mm against 46 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 169 mm average is a reasonable planning figure, not a promise.

Wind is light at 0.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 88%, which at 12.5 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How March sits in the year

The month is on the way up: 1.7 °C warmer than February, and April adds another 2.3 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.8 hours of daylight, gaining 1.5 hours across the month. That is between Eugene's extremes of 15.5 and 8.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 25.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Eugene versus nearby

If Eugene is one option among several, the nearby comparison is worth making. Portland is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Tri-Cities is a better bet in March — 2.4 °C warmer, 11 days less rain.

So: March is a compromise. July is 56 points better and is what Eugene is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
