Everything below is collected in one spot so you do not have to cross-check Guadalupe climate: monthly averages by hand. The gap between Jan and Jun is 13.8 C here: 13.6 C against 27.4 C. Precipitation peaks in Sep (6.58 mm/day) and bottoms out in Dec (0.65 mm/day), so a 10.1x difference between the two. Taken together that is roughly 708 mm of rain a year for the grid cell. The build runs on a schedule and caches the last good response, so the numbers stay put even when the upstream API is having a bad day. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Guadalupe climate table shows
Values are multi-decadal climatological averages for the 25.67663, -100.25907 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Is Guadalupe climate data a forecast?
No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
