🌡 The weather here, in general
Boise runs the full range. The warmest stretch, around July, averages a high near 94°F, while January nights average 25°F — a 69-degree spread, so a coat that works in January is useless by July and the other way round.
Expect around 55 days a year at 90°F or above, concentrated in July. Heat illness climbs sharply on consecutive hot days, so the third day of a streak is more dangerous than the first.
Snow shows up most years — about 24 inches — but rarely in quantity. 106 freezing nights a year matter more, because the risk here is ice rather than depth.
This is dry country — roughly 14 inches a year. When rain does come it tends to arrive all at once, which is why flash flooding is a desert problem as much as a tropical one.
