Weather in Eugene in April

Shoulder season. April is shoulder season in Eugene — cheaper, quieter, and a genuine gamble. You should expect rain on 16 days of the month, which is more days wet than dry.

April ranks 7 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 16 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 14.8 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 33.1 °C and the coldest night fell to -2.9 °C, and the wettest single day dropped 69 mm — roughly 57% of the month's rain in one day.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 231 mm against 71 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 122 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 86%, which at 14.8 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How April sits in the year

The month is on the way up: 2.3 °C warmer than March, and May adds another 3.7 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

13.4 hours of daylight, gaining 1.4 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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

April 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 April — 4.1 °C warmer, 9 days less rain.

So: April is a compromise. July is 45 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.
