🌡 The weather here, in general

Allentown runs the full range. The warmest stretch, around July, averages a high near 86°F, while January nights average 24°F — a 62-degree spread, so a coat that works in January is useless by July and the other way round.

The thermometer rarely spikes — only about 13 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Snow shows up most years — about 25 inches — but rarely in quantity. 100 freezing nights a year matter more, because the risk here is ice rather than depth.

Rainfall averages about 48 inches a year, wettest in August and driest in November.
