Chiricahua / Madrean Sky Islands

**Tier A is locked in despite Arizona's brutal July heat—you've got the moisture window that matters.** Sustained above-threshold soil temps and that critical 7-day moisture consistency are pushing Oyster, Chanterelle, and Dune Stinkhorn all into high viability simultaneously, which is rare at this elevation in midsummer. The only real constraint is desiccation risk; you're sitting at the edge of that moisture band, so anything above 0.51" of precip in the next 72 hours extends your window significantly. What to watch: if afternoon monsoon activity kicks in (typical late July pattern), this goes from A to A+. If the next 14 days stay dry, watch for the transition to late-monsoon species (puffballs, earthstars) as soil dries out in late July–early August. The Chiricahuas often catch orographic lift from storms that miss surrounding basins—dial in your microclimate. **Hot tip:** Scout north-facing draws and seep areas in the 7,000–8,000 ft band where soil stays cooler and collects runoff; Chanterelles will fruit there 3–5 days ahead of exposed slopes.
