August 2010 Revisited

Compared to historical averages, August in Hood River was pretty much like July in Hood River. Warmer than long term averages, but cooler than recent years. It was drier than average, with (surprisingly) average August wind speeds.

At my weather station, the average temperature of 68.9° was warmer than long term averages (1897 to present) of 66.6°, but cooler than more recent (2000-2009) averages of 70.0°. I'm surprised by my station's average temp for August, as it seemed cooler than that. Tom's Westside station, which is only a few miles away, was 1.3° degrees cooler than mine for the month. However, Nick's Underwood station's average was only 0.2° cooler than mine, so who knows. Darn micro-climates around here...

There was a 5 day "heat wave" starting on the 13th, peaking at 101° on the 16th, and a very brief hot spell on the 24/25th, with a high of 97. The high heat index for the month was 98°, and the low wind chill was 46°.

Rain finally arrived on August 30th and 31st, breaking a 71 day dry spell. See the two previous posts for all the lurid details.

The 24 hour avg wind speed was 4.4 mph, which was exactly average for August at my station. Like the temperature average for the month, this average wind speed doesn't jive with what I expected the numbers to show, as it seemed pretty darn windy in August. However, other personal weather stations around the area showed even a lower 24 hour average wind speed, so I guess mine is valid. I think that maybe it was just that the wind hardly ever let up throughout the month, but didn't make for higher 24 hour averages. In any event, July and August were great months in the Gorge for wind sports enthusiasts!

There was 1 official local weather record set in August. On the 6th, the "high low" temperature of 67° surpassed the old record of 66° (2000).

The tabular data below is from my home weather station. To view its August 2010 monthly summary and graphs at Weather Underground, click here.

The "historical average" numbers for temperature and rainfall are from the Hood River MCAREC data. Historical wind average is from my station's 2000 to 2009 data. Note that average wind speeds include all 24 hours of the day and night, which is why they are way lower than daytime peak winds. In addition, the wind speeds at my station are considerably lower than on the Columbia River.

	High	Low	Average	Historical Average
Temperature (F)	101	46	68.9	67.3
Wind (mph)	34		4.4	4.4
Rainfall (in)	0.07		0.10 (total)	0.37

Even though August wasn't remarkably cool, at least at my station, the 2010 June through August summer period was definitely on the bluish side.
