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.
Temps in AZ.
I agree with Nancy Cook. It has already been 113° here in Glendale AZ and averaging 85-87° at nite. Old Farmers Almanac didn't take into consideration manufactured weather and now we have these HOT Santa Ana winds just like Ca. Low desert area sucks in the Summertime and that's why I'm going back to the forest in higher elevation. Stay cool y'all!!!
WAY OFF
The average for Gilbert AZ in July is 100-103 and it goes up after that through September. This is not even funny, it's so wrong.
Average temps
Yes, I agree that's way low. Perhaps they're combining both high and low temps together to come up with the average?
Average daily is not average high
This is the average daily temp (Xbar). the mean of the sum of the day divided by the time of the day.
This seems completely reasonable. My house in Tucson has a morning temp of 60 and a high of 103.
Not accurate what so ever.
First off, yeah, I understand this is all predictions, well these are horribly off. Average temp of 87 degrees?? Yeah right. Its already in the mid 90's and should reach 101 in a couple days. This is legit, as inaccurate as possible. This last winter wasn't something unheard of. It was actually very similar to the winter of 2016-2017 honestly, now this is for Southern Nevada, not sure about you other guys. Yeah, Vegas actually had snow, which yes is rare, and has not happened in many year but everything else is just part of the cycle, none of that global warming BS.
accuracy
It’s early days in June, so we’ll see what transpires—and perspires. Our predictions are traditionally 80% accurate, sometimes more, sometimes less.
N.M. Weather
I have been tracking it for 25 years, boots on the ground. 2018 and 2019 winter has been the absolute wettest I have ever seen. Ground cover this spring was phenomenal, tough thick and silky with resilience. We have had continued moisture in rain sleet and snow at rates unseen since the early 80’s. I ran out of my normal need of firewood back in April, but needed an additional 3 cords of firewood for warmth, a thing I was not prepared for. Tomorrow is traditional planting day and snow is falling. It is wet and cold, windy and brisk, overall ideal for northern climes but unheard of in NM these last decades. The potato plants are loving it, the beans not so much. This is glorious weather, more please! I pray God the drought is ended.
glorious weather
It sounds glorious, indeed. Thanks for taking the time to let us know.
temperatures
You have 70s-80s as above avg temp here for May and June? No that is low,
we can be in the 90s and 100s in these months.
