predicted weather for Tucson, AZ in April

My employer is trying to schedule an outdoor event and we really need to know the weather for the month of April. Can you help me?


Looks like an exceptionally cool summer...Cool for Arizona.


I find it amusing how the untrained will challenge the Almanac which is totally accurate and most commenting on here weren’t even thought for yet. Now THAT’S a huge ego there!

September 9 & 10 unusually cold

Any thoughts on this cold front that has come to the las cruces/el Paso area these last couple of days? I started some late season crops in hopes that global warming would play in my gardens favor but it seems I might be wrong. Love what you do, thank you.


This chart appears to be incorrect. I know that it has been hotter than normal in July and August. This chart contradicts that. Therefore, the chart is wrong

Hi, Mark, 

The chart corresponds to the monthly temp and precip forecasts/predictions shown above (and for the year in the print edition). Its may not be true to the actual conditions. Thanks for noting.

Much needed rainfall

Any thoughts on this winter's predicted La Nina weather pattern impacting one already drier than normal Southwestern region? Thanks!

Dry and drier

Sorry, not going to rain on your parade, in all likelihood. We are predicting below-normal rain and snowfall in the Desert Southwest. … but cooler.

global warming

The term "global warming" is very misleading. I have found that too many people think it means that there will be no more cold temperatures. "Climate Change" is more accurate. As I understand it, what it means is that temperatures and conditions are becoming more extreme. Hot areas get hotter, and cold areas colder. Hot seasons are hotter and cold seasons are colder. Dry ones are drier, and wetter ones wetter, etc. When you add up all those hotter and colder temperatures, and average them out, you get a higher number. THAT'S HOT! Hence the term "global warming". (A scientific person could do a better job of explaining this.)


The Editors's picture

We agree largely that “climate change” is the more appropriate phrase. As scientists, and the public as a result, come to a better understanding of just how things are changing, we will probably see it as the more commonly used term. One small point of interest/observation (to this editor) on your definition is that it seems like the cold is not getting colder—at least not for as long and deep as it did a few decades ago. Time will tell. Thanks for your thoughts.
