Gaps appearing in floorboards

It's that time of the year again: gaps appearing in floorboards

In this period our web site is being found by a lot by people "Googling" on: floorboard gap; floorboard gap filler; gaps in floorboards, etc.
We "wood like" to explain that in this time of the year and with this weather that gaps appearing in floorboards is pretty usual. We keep track of the air humidity in our house and shop on a daily basis and during the end of autumn and winter it can drop as low as 35 - 40%

Wood works all year round and when the weather (climate) gets dryer, wood will get dryer also (as will your skin). Then it is very normal for floorboards to shrink and for gaps to appear. These gaps will disappear again when the air humidity gets higher

It's no use to fill them; it's part of the way wood works.

What you could do (to keep the wood and also yourself healthy): hang ceramic water containers on radiators (check regularly that they are still filled with water; you can also add a few drop of a fragrant in for a nicer or fresher smell) or hang a damp tea-towel (not dripping wet!) on radiators; that will increase the humidity slightly.
