Living with Belgium’s climate

What the numbers mean for a garden, a driveway, a furnace and a free afternoon.

The garden window

159 frost-free days. The last frost comes by May 5 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Oct 12.

Snow season

About 42" a winter over 12 days with an inch or more, most in January. Snow covers the ground about 58 days a year.

Furnace season

Months averaging under 55° run from October through May. Heating is 95% of the year’s heating-and-cooling load.

Summer heat

About 4 days a year reach 90°, and July afternoons average 80°.

Get outside

The nicest months are May, June, July, August and September. 8.4 miles of trails are waiting.

Heating & cooling

Heating and cooling a home in Belgium

95% of the work is heating, so the furnace matters far more than the air conditioner.

Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. Source: NOAA station normals.

Year to year

How much a month can swing

A normal is an average. January swings the most: from 1991 to 2020 its average ranged from 10° to 32°. June is the most reliable, staying within 9°.

Are Belgium winters worth it?

Temperatures and rainfall come from NOAA’s gridded climate normals for Belgium itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Port Washington, WI (6 mi, snow) and Belgium WWTP, WI (3 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Today’s forecast: National Weather Service.
