Weather in Anchorage in April
United States · 20-year averages, April
The month to avoid. Of the twelve, April is the one to avoid. Highs sit at 4.7 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
April ranks 6 of 12 in Anchorage: past the worst of the year but short of July, which is the month to book if the dates are open.
Rain on 9 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 4.7 °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: 15 nights fall below freezing; the day barely swings — 5.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 14.9 °C and the coldest night fell to -15.5 °C.
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 66 mm against 15 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 38 mm average is a reasonable planning figure, not a promise.
Wind is light at 6.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, which at 4.7 °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: 5.5 °C warmer than March, and May adds another 6.7 °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
14.6 hours of daylight, gaining 2.9 hours across the month. That is between Anchorage's extremes of 19.3 and 5.5 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 27 °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 Anchorage versus nearby
If Anchorage is one option among several, the nearby comparison is worth making. Prince George is a better bet in April — 3.8 °C warmer, 3 days more rain. Tofino is close enough to be a coin toss — 6.1 °C warmer, 8 days more rain.
So: April is a compromise. July is 36 points better and is what Anchorage is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
