February Revisited

Compared to historical data, February in Hood River was colder, drier, and less windy than average. To view my weather station's monthly summary and graphs at Weather Underground, click here.

The average temperature was 1.1 degrees colder than long term averages, and 2.6 degrees colder than more recent averages (2000-2008). Wind speeds were low, due to persistent inversion conditions.

In fact, if I had to sum up February in three words, they would be: "Persistent Inversion Conditions". However, as is typical during inversions, there was an abundance of sunny weather at higher elevations and at the Mt Hood ski areas.

There was one weather record set in February. On the 27th, the official rain total of 0.98" broke the old record (for that date) of 0.95" (1976).

The data below is from my home weather station. 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 2008 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 speed at this station is considerably lower than on the Columbia River.
