SUNSHINE GUIDE TO BRUSSELS, BELGIUM
SEASONS: Brussels has a four-season year based on temperature and the
vegetative cycle. Spring (April and May) brings blossoms and new growth.
Summer (June through September) means no more frost and snow, while vegetation
is in full foliage. Autumn (October and November) sees the deciduous trees
drop their leaves, the annual plants die, and the first frosts appear. Winter
(December through March) is the season of vegetative dormancy, and subject to
snow and below-freezing temperatures.

SUNSHINE GUIDE TO BRUSSELS, BELGIUM
SUNNIEST MONTHS: May through September sees the most sunshine, although it's
not a lot. In general, only 35% of the year's daylight hours will be sunny.
May has the most, with 44%, while December only gets 15%. From November
through February, about half the days will see no sunshine at all. Even when
it does shine in winter, it's pretty weak. On Midwinter Day, it will only get
less than 16° above the horizon at high noon.
WARMEST MONTHS: July and August, with warm (not hot) days and cool nights.
The hottest actual temperature of the year will be around 90°, but will feel a
degree or two cooler. It will probably occur in July. Sensible temperatures
(the ones you actually feel) of 90° or higher are rare, and can be expected no
more than once or twice each summer--sometimes not even that.
With summer days being mild to warm and nights generally cool, only very
rarely will the nights will be hot enough that you will sleep better with some
sort of room-cooling. Generally speaking, an open window is more than enough
to cool the room.
COOLEST MONTHS: January and February. At this time of year, you can expect
frosty mornings on just under half of the days. About one day a week, and
Arctic front will move through, and you should be ready for afternoon
temperatures to remain below freezing all that day. The coldest temperature
of the year will be around 14°, and will probably occur in January.
Even during the coldest months, most of the precipitation will come as
rain. What snow does fall, does not remain on the ground for long.
DRIEST MONTHS: May and September. Some 43% of the year's days will get no
measurable precipitation; that is, they will get less than a hundredth of an
inch. May and September will have 54% such days, whereas January will get
only 27%. A "dry day" in the table, however, is one with less than a tenth of
an inch--a more useful measure. It takes at least that much to wet the ground
under the trees.
Much of the winter rain that characterizes the area comes in the form of
day-long light drizzles mixed with heavy mists. Although they don't bring
much rain, they do get things wet. The Irish (who get a lot of them) refer to
such weather as "soft" days. Philosophical acceptance and warm woolens help.
THINGS TO KNOW: The city will often have a distinct "urban heat island"
effect. Under windless and rainless conditions (or near), the city center
will be many degrees warmer than the outlying suburbs. This is especially
noticeable at night and in the winter. Precipitation of any kind diminishes
this effect, and a strong wind will eliminate it completely. Snowfall is also
much lighter in the city center, and melts more rapidly. The table data refer
to this city center.
