Every town next door is within a degree of Lake Como in January and July, closer than the 5 km grid can tell apart. Tap a town to see its climate.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Lake Como averaged 2.3° warmer than the 1900s. The biggest change is in February (+4.0°).
A bigger shift than in 98% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Lake Como compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Lake Como’s place among New Jersey’s.
