L.O. Weather Information ~ Our Neck of the Woods….

sunOut of state and wondering what you can expect for weather in Lake Oswego after your big move?  Planning your house-hunting trip and wondering what you can expect?   I’ve added a few tidbits of information for you below to help give a better picture of life in Lake Oswego… weather-wise.

My personal experience in Lake Oswego is that July varies from cloudy days here & there to weeks of cobalt blue skies, ranging from a high of 70 degrees to the 90’s. We spend most of the month of  August in the 90’s with some 80’s thrown in here & there and the occasional 100… that’s based on the last few years, and/but the table below lists the “normal” high temps in Lake Oswego in August at 80 degrees. So, we then get into definitions of “normal” : )  Anyway, it came from AccuWeather.com . This site also shows you the pollen index and other helpful data such as yesterday’s weather breakdown:

Now, the Farmers Almanac is ‘Old Faithful’ as far as weather goes.  This link will allow you to look at any date in Portland (they don’t call out Lake Oswego, but hey, it’s close). It will also give you precipitation and pressure data.

If you’d like blow-by-blow information on Lake Oswego weather, WeatherForYou.com will accommodate with detailed forecasts & hour-by-hour breakdowns for the previous 48-hour period.  Then there is detailed morning & evening information for  every day in the forecast at City-Data.com

Most of these sites will challenge you with advertising, but I hope some of them prove helpful prior to your next trip to Lake Oswego.  Remember, if you are heading this way, you can always email Dianne or myself to find out whether you will need to bring your bathing suit or sweater.  It’s the summer home-buying season, and we’re really enjoying working with all of our Property Blotter readers. We look forward to meeting you soon as well.  Gotta run…. houses to show!

Rainfall in Lake Oswego

I think it is fair to say that the rainy season has begun. A Russian immigrant, who has become a good friend of my family, once commented to me that Oregon only has two seasons: wet and dry. If you are following the blotter from out of the area, and perhaps even considering moving here, I think it is only fair to be completely honest with you about our weather.

As you have read in several recent posts, we have a glorious fall with the trees turning colors and sunshine that is bright. It is also in the fall that the transition happens from mostly sunny days to mostly rainy days. The rain will dominate the forecast until about April. Then the transition will happen back to mostly sunny days.

Our rainfall is unique in that it seems to fall in a steady mist. While we do have days that the rain falls heavily, for the most part it is a soft and steady drizzle. I have heard it compared to the rainfall in Ireland. Because it is usually a gentle rain, you might be surprised to learn that umbrellas are used infrequently. Oregonians generally just put on a good coat and go out in it. It is really quite lovely, once you get used to it and quit seeing it as an inconvenience. It is also really good for maintaining lovely skin.

So we get very little rainfall in the summer and quite a lot of rainfall in the winter. However, in my experience, there are always surprises. The summer after Mt. St. Helens erupted never happened. It was cold and gray with very little sunshine. And it also seems to me that February tends to have many sunny days. Perhaps that is because after November, December, and January, the decreasing rain is so noticeable. I will also tell you that when the sunny weather starts again in the spring, people really make the most of it. On that first nice day everyone spends the day outside: walking, gardening, going to the coast, and just generally taking advantage of the nice conditions.

I have learned to love the rain. The sound of it makes me sleep better at night and I credit it with giving us our lush landscaping. When I visit other states that don’t get this kind of rainfall, I can’t help but feel like they just don’t have the beauty that Oregon does. I’m a fifth generation Oregonian. I guess it is just in my blood.
