Indian summer
It has been an Indian Summer here in Beatty Nv. ,lows in the 50`s highs in the upper70`s no wind,no rain for almost 2 wk`s
Rain over this winter?
I'd like to know about rainfall predicted for Albuquerque/Rio Rancho area. What month is the best time for roof replacement? The expected rainfall specified by the week expected would be enormously helpful. Thanks.
Winter Predictions for Show Low
I love how I search for winter predictions for Show Low, AZ and it shows me the winter predictions for all of the SW of the United States. For those who are not familiar with Show Low, we are located in a Pine Forest in the White Mountains of Eastern AZ. Our climate is vastly different from the desert areas of the SW that this is focused on. Overall it is just very inaccurate, and if I wanted to see predictions for the SW as a whole, then I would have searched that. Seeing how it is going to be down in the desert areas of Phoenix and Tucson is practically irrelevant to me. I have read other people's comments, and from the looks of it, it seems that this website is just overall not very accurate.
Long-range weather predicting
A lot of people just do not understand what this is. I see so many questions about local weather or a specific date. The Old Farmer's Almanac long-range weather predictions are made way in advance (maybe 18 months). They are based on climate regions and above/below historical averages for temperature and precipitation. And it's true that microclimates are different than weather zones but that's a given. You can't expect these predictions to be any more than general and regional. Historically, I have found that the weather shift happen a few weeks prior to what they say or a few weeks after they say. So you have to look at these at trends. Will it be an extra snowy winter or not?
You clicked on the wrong zone--
There's another zone Show Low would fall into. Back out to the big map and click the area that includes Flagstaff.
I live in the Valley- so I know what you mean, but the overall predictions from the Old Farmer's Almanac are very good year after year.
Re: The cold.....
My only hope is that the hard freezes don't hit for as long as possible in Santa Fe. I have beautiful melons I want to ripen, and I give them probably at least 30 days. I have frost blankets, I have bottles that I will mostly likely leave inter mixed in the garden as they will warm during the night. Any other suggestions?
Average = (High + Low) ÷ 2
It seems that most of these comments are considering the average High temperatures for your areas, which is why this number seems low. The average temperature consists of both the daily high and the daily low (please see formula above for finding the average). In my area the averages listed in this reference have been spot on.
I appreciate having a free reference with all this data well organized and accessible.
Good point, but data is still off.
You’re doing good in showing those who don’t understand, the formula and how it works. The only problem is that they’re predictions have been precise but inaccurate. The past 3 months their data has been precisely wrong in the Southwest. June’s prediction called for above average temperatures (wrong). July and August called for low temps and high precipitation: Also wrong.
I think it really does matter where you are.
We're south of Tucson and the predictions have been dead on. Cooler than our average and much, much wetter. If this winter is a repeat of last winter, we're in for a ride.
Dead on for Las Cruces
These predictions nailed it here in Las Cruces. It's been wet and hot but temperatures are lower than the usual for August and September. So much rain that grass is growing where there is usually just sand and hardscrabble. The trees have been blooming very nicely from all the moisture.
