The winter season can often feel long and gloomy, with lots of rain and short days. Like animals that hibernate, we tend to slow down and wait for warmer weather. But here’s something we often forget - to enjoy those sunny days, we need a good rainy winter first!
Let’s look at why winter rainfall is so important and how it helps us, nature, and wildlife.
Water resource replenishment
Winter is the key season for refilling our water supplies. Rain helps to top up rivers, reservoirs, and underground water sources (which we call aquifers). Cooler temperatures and slower plant growth mean less water is lost to evaporation. This stored water is ready to use in spring and summer, helping to reduce the risk of drought and shortages when the weather turns hot.

Drought resilience
Steady rainfall through winter builds drought resilience. It allows groundwater and rivers to recover after dry/warm summer months. This helps homes, businesses, and nature when water demand and temperatures rise again. Good winter rainfall also reduces the likelihood of water restrictions like hosepipe bans during dry spells in the following spring and summer. The wetter the winter the more water we have for the summer ahead.
Reducing the need for watering
Indoor and greenhouse plants need far less water in winter. With shorter days and lower light levels, they grow more slowly and lose less moisture. Don’t follow your summer watering routine. Overwatering can cause root rot because the soil stays damp for longer.
Check the soil before watering. If it still feels moist, wait a few more days. A plant that needed watering every few days in summer might only need it every few weeks in winter.
If you collect rainwater, use that instead of tap water. It’s softer, more natural for plants, and there is usually enough to meet their reduced needs.
How to help wildlife during winter
Collect winter rainfall: Keep water butts out during winter to capture rainfall. This stored water can help you care for your garden and support wildlife during the drier summer months.
Provide water: Keep a shallow dish or birdbath filled with fresh water. In freezing weather, gently break the ice so animals can drink.
Support habitats: Leave leaves and overgrown areas in your garden. They offer shelter for insects, amphibians, and small mammals. Check piles before setting fire to them as hedgehogs may be hiding there.
Provide food: Use bird feeders and put out nuts, seeds, and suet to help wildlife when natural food is scarce.
