WALLA WALLA — July is the first full month of summer and if predictions hold true, expect hot days to rule.

Already off to a hot start, above-normal temperatures are expected to continue this month, according to the national Climate Prediction Center. The forecast also calls for near-normal rainfall, which if history is any guide can be summed up as “not much.”

But first a quick look back at June.

The past month was only slightly warmer than normal with an average daytime high of about 79 degrees, just one-half degree above average. Nighttime lows were about 55 degrees, which was 1 degree above normal.

The hottest day was 90 degrees on June 23 and the coolest night came on June 6 when the mercury dropped to 49 degrees.

In terms of precipitation, June finished a bit on the dry side with a total of 1.16 inches of rain, a mark 0.12 inches below average. Most of the month’s moisture fell on three days, June 16-18, while the rest was spread out on four other days. There were 23 days with zero or trace precipitation.

Rain and snowfall for the year now stands at 9.21 inches, which is 2.71 inches below normal. Since October, the water year precipitation as measured at Walla Walla Regional Airport has been 12.30 inches, a mark 6.64 inches below normal.

The highest wind gust was 35 mph, on June 12.

The coming month marks the start of the dry season when rainstorms are few and far between. Normal precipitation for July is 0.59 inches while the normal high is about 89 degrees and the normal low is 61 degrees. Only August has a lower average precipitation, 0.57 inches, based on a 30-year average.
