Lopez Weather Summary - July 2026
August 5, 2026
All things considered, our weather in July 2026 was pretty acceptable and nice, for a coastal Pacific Northwest location.
High temperatures were generally higher in the northern half of the island, compared to the southern half. My temperature extremes were 86°F and 46°. My home location had three days with highs in the 80s, sixteen days with highs in the 70s, ten days in the 60s, and two days with highs only in the upper 50s. I had seven days with lows in the 40s, and 24 days with lows in the 50s. Many northern-half weather gauges had 2-3 days in the 80s, with some locations almost hitting 90° (89°). Most southern-half gauges did not reach the 80s. Some Southend locations might have considered their Julys as fairly cool this year due to the effects of the cool offshore waters and breezes. But overall, our July was temperate and average, and nothing extremely hot like elsewhere in the country.
We had four episodes of rainfall in July, which in my book was a pretty nice change from some of our ultra-dry Julys in recent past. Last year July 2025, the cumulative island rainfall varied from 0.01 to 0.06 inch of rain. In July 2026, rainfall varied from 0.45 to 0.98 inches, with two online gauges recording 1.5 to almost 2 inches of rainfall. While I sometimes have my doubts of the accuracy of far-skewed readings, thinking the automated weather gauges might be malfunctioning, we did have two (or was it three?) days where thunderstorms rolled through our area, and it is conceivable that there could have been a heavy rain squall in some localized vicinities. My understanding is that Lopez did not have any actual lightning strikes, but San Juan and Orcas did. But we sure did have some nice rolling thunder in the background!
The attached map shows cumulative July 2026 rainfall at five CoCoRaHS rainfall stations on Lopez. I had 0.87”, Jack Giard had 0.83”, Swifts Bay 0.98”, Lopez Village 0.74”, Davis Bay 0.45”, Islandale 0.74”, and Agate Beach 0.60”.
Wildfire risk was “Moderate” on Lopez for most of July.
Evapotranspiration measurements cumulatively totaled 3.32 inches for July 2026.
