Geography

Heron is located at 48°3′27″N 115°57′37″W (48.057437, -115.960373).[1]

According to the United States Census Bureau, the CDP has a total area of 3.4 square miles (8.8 km2), all land.

Climate

Heron has a continental, quasi-Mediterranean climate (Dsb) that has more in common with northern Idaho and the Pacific Northwest than the rest of Montana. It has one of the wettest climates in the state (outside isolated mountain areas), averaging nearly 34 inches of precipitation per year. Winters are wet and often snowy with occasional rain; summers are mostly dry with sunny, warm days and cool to chilly nights.

Another very striking feature of Heron's climate is the patterned, extremely large seasonal variation in diurnal temperature range: only 10-11 degrees in the wettest months, November through January, expanding to nearly 35 degrees in the driest months, July and August, reflecting prevalent low humidity during those months. Around 11 days per year reach 90 F., while 100 F. is a very rare occurrence. Nights are cool year round with freezes having been recorded in every month. On average, the lowest temperature each year is -12 F., placing Heron in hardiness zone 5B.

Average monthly precipitation is very high by Montana standards, especially in the wettest months of November through January, but Heron experiences continuing moderately wet conditions each month from February to June. In May and June, Heron shares with the rest of Montana some frequency of shower and thunderstorm activity, making these the wettest months in virtually all other areas of Montana, but not in Heron due to its exceptionally wet winters.

Overall, Heron's average annual precipitation cycle is similar to that of the Pacific Northwest in its dry summer and wet winter (with a November maximum, as in Seattle, WA), but somewhat transitional into the typical Montana and Wyoming pattern of a May or June maximum, reflected in Heron's continued relatively high rainfall those months. The combination of these factors with possible orographic lift results in Heron being one of the wettest locations in Montana, mostly a dry state elsewhere.
