First 90° Day Stats

Temperatures are forecast to reach the 90s for the first time this year later and will likely reach daily records on some days. There is even great potential (90% chance) of tying or breaking the February record high in Phoenix.

Strong high pressure over the region will lead to well above normal temperatures. Afternoon highs will reach the middle 80s to middle 90s. This heat will result in Minor HeatRisk across the lower deserts. So make sure to use extra precautions if spending time outdoors, especially if you're more sensitive to the heat.

A broad area of high pressure ridging will support well above normal temperatures across the Desert Southwest through the beginning of March.

The average first 90° for all three of our climate sites occurs in mid to late March. However, the earliest 90° for all of the climate sites has already passed. So even though we're forecasting for all three sites to reach 90°+ by the end of the week it won't be the earliest occurrence.
