April 5 in Graham lands right in that shoulder-season sweet spot — historically mild, with an average high of 56° and a low of 37°. There's a coin-flip chance of rain (52%), but snow is essentially off the table. The date has seen everything from a balmy 77° back in 1966 to a bitter 26° in 1975, so pack a layer just in case.
Graham's weather has real range — from a scorching 102° on July 30, 2009 to a brutal -1° on December 23, 1983, that's over 100 degrees of separation between its extremes. November is when the Pacific really opens up, as evidenced by the all-time wettest day of 3.59 inches falling on November 7, 2006. And that 16 inches of snow on December 27, 1974 is a reminder that this corner of Washington can still get buried when conditions align.
Graham follows a classic Pacific Northwest arc: mild and wet in winter, warm and dry in summer. Highs peak in mid-July around 77°, while January and December both average just 44–45°. If you're trying to dodge the rain, aim for July or August — the wettest stretch of the year doesn't arrive until late November, when weekly precipitation averages over an inch and a half.
