Rain
June is one of the drier months of the year but, occasionally, thunderstorms will rumble in - especially at the end of a fine period of weather.
In dry spells you may still need to water, particularly in south-east England and East Anglia. Don’t wait for plants to wilt before taking action and pay particular attention to new plantings and seed beds.
Sunshine
Plenty of strong sunshine will continue to ensure that plants grow rapidly this month. Levels vary across the country, but Scotland and Wales average around 160 hours of sunshine. In East Anglia and south-east England over 180 hours can be expected.
Temperature
Afternoon temperatures can reach 27°C (80°F) in most parts of the country during June. This is particularly likely when there are few clouds in the sky, allowing the sun’s heat to easily reach the ground.
Ventilate conservatories and greenhouses in the daytime to prevent the sunshine causing inside temperatures to soar. Be ready use blinds if shading paints haven’t been applied to the glass. Prolonged warm spells will also accelerate the rate at which the soil dries out.
Wind
Light westerly winds cross the country, bringing generally cloudless conditions. There should be fewer gales than any other month, but it’s worth ensuring that herbaceous borders are well staked, just in case gusts flatten perennials.
