On International Dawn Chorus Day, how does the weather affect birdsong?
The dawn chorus is one of nature's greatest concerts. There's something calming and magical about waking up to the sound of birdsong - a timeless signal that the day has begun. Sunday 4 May is International Dawn Chorus Day and it's celebrated by people around the world who rise early to appreciate this natural symphony.But can the weather have an impact what we hear?
Why do we love birdsong?
Scientists believe that the sound of birds singing makes humans feel safe. The soaring melodies are a reassuring sign that all is well in the environment. When birds fall silent, it can indicate that bad weather is on the way, or that a predator is nearby, meaning the absence of birdsong can feel unsettling - even if we don't consciously realise why.
What impact does the weather have?
Still, dry mornings are the best to hear the chorus in all its glory. Even during a quiet, steady drizzle, most species will sing much as usualBut according to Daniel Johnson, from the British Trust for Ornithology:"Birds tend to avoid singing in bad weather conditions. This includes windy, rainy or cloudy conditions as during these times they're usually low down conserving energy"A study, external carried out by researchers in the USA also showed that exposure to high temperatures can reduce song production.
When is the best time to hear the down chorus?
The best time to listen is around 30 minutes before and after sunrise, when birds are most active. On Sunday 4 May 2025, sunrise in the UK ranges from around 05:22 BST in Edinburgh to 05:39 in Cardiff and Belfast, so the ideal time to hear the chorus is roughly between 04:50 and 05:50. You can find out the sunrise and sunset times for where you live on the BBC Weather website or app.Blackbirds and robins are usually the first to sing, followed by wrens, thrushes, and warblers as the light increases.

Wild swimmers in the South West prepare for Strawberry Moon dip
A full Strawberry Moon will grace UK skies tonight, coupled with a rare phenomenon not to be seen for almost 20 in the northern hemisphere already spotted an almost full moon sitting very low in the sky on Tuesday, but the full peak of the moon will appear later. BBC Weather presenter Sophia Herod said the Strawberry Moon would be "the lowest full moon until 2043" and may appear wild swimmers around Devon and Cornwall are preparing to take a dip outside under the moonlight to embrace the "magical" full moon experience. Matt Newbury, who runs monthly full moon swims in Paignton said he would be taking to the water at Goodrington Sands as part of an informal event."It took me almost a year to swim in a full moon," he said."We started trying to do full moon swims about three of four years ago, but it was either raining or cloudy and we didn't see a moon for months, but we know it's up there.""It's amazing because you get that whole moon river, that trail of light on the water," Mr Newbury added. "It's just really magically being under the moonlight. It's a bit daring, it's a bit naughty."Chagford Pool, near Dartmoor, said it had sold out its ticketed full moon swim and was looking to host more in future. Why a 'Strawberry Moon'? Sophia Herod said the Strawberry Moon was named after "Native American and European cultures as a way of signalling a time to harvest wild strawberries".Full moons were given nicknames to help keep track of time and monitor the changing Strawberry Moon may appear to take on a reddish tinge, but it is nothing to do with its position of the moon so close to the horizon means the light it reflects towards Earth passes through the thicker, lower layer of you manage to catch the Strawberry Moon on camera, why not share your photographs with BBC Weather Watchers.

Humidity - all you need to know
Muggy, sultry, clammy, sweaty - all words used to describe a hot and humid humidity can often make people feel uncomfortable and you may find it difficult to sleep. And humid weather is sometimes accompanied by thunderstorms and heavy rain. What is humidity? Humidity is a measurement of the amount of water vapour in the air. Warmer air can hold more water vapour than cooler air, if there is plenty of water available. The tropics are very warm and also very humid and the air there contains lots of water vapour. Conversely, there is very little water vapour over the cold Arctic and Antarctic or the deserts of the Sahara, therefore humidity would be much lower. It's all relative We tend to measure humidity in terms of Relative Humidity (RH). This looks at how much water vapour there is in the air compared to how much there could be at that temperature. You can find the RH for where you are on the BBC Weather app. If it's 100% then it is fully point temperature is also a measurement of humidity. This is calculated by cooling a surface to the point at which the air condenses and looks like the dew seen on grass in early mornings when the temperature has dropped over night. Is dry heat better than high humidity? While there are health effects from low humidity - including dry skin and itchy eyes - our bodies tend to find it more difficult to cope with high humidity. When we get hot, our bodies sweat to help cool us down but high humidity makes it more difficult for your sweat to evaporate into the air and this can leave you feeling hot and sticky. Combine high humidity with high temperatures and for some people this can lead to dangerous levels of overheating and heat stress. Where does humid air in the UK come from? In the UK, humid weather tends to happen when winds are coming from the south. That can be from a tropical maritime airmass bringing moisture laden air from the Atlantic, but, a tropical continental airmass can bring a more dramatic change in humidity and weather. Our highest temperatures of the year come with a southerly wind and usually with high humidity. Often, this muggy air gives way to thunderstorms and heavy rain and once they pass, the air that follows is usually cooler, less humid and more 'comfortable'.

Best places in Scotland to see tonight's extremely low Strawberry Moon
The Moon won't appear this low again until 2043- so where will you be able to see it? Tonight will see a rare astrological event known as the 'major lunar standstill' in which the Strawberry Moon - the name for June's Full Moon- will appear extremely low on the horizon. Although we see a Full Moon roughly every month, tonight's will be extra special- but particularly difficult to spot. While the Strawberry Moon is usually the lowest Full Moon of the year, it hasn't appeared so low in the sky since 2006, and won't be again until 2043. This is because of the major lunar standstill, which occurs once every 18.6 years. Across the moon's nearly 20-year-long cycle, it follows a tilted orbit around Earth. Major and minor lunar standstills occur when the Moon rises and sets at its most extreme points on the horizon, appearing unusually low or high in the sky. During the Strawberry Moon, Earth will be approaching its farthest distance from the Sun in its orbit. The Moon will also be as far from the Sun as it can possibly be in its orbit around Earth, in one of the furthest full moons from the Sun of the year. The Strawberry Moon will rise tonight, June 11 at 10.46pm BST, and it reached its full phase at 8.44am BST. But to catch this extremely low moon tonight, a clear horizon and a dark sky will be necessary to avoid obstructions. Here are some of the best places in Scotland to catch the Strawberry Moon this evening. Where can you see the low Strawberry Moon tonight? Beaches A beach is one of the best places to go for an unobstructed horizon, and Scotland is home to many. The best beach for stargazing, however, is Luskentyre Beach on the west coast of South Harris in the Outer Hebrides. This beach's lack of light pollution has led to it being named one of the best in the whole of the UK for observing the wonders of the night sky. For those on the mainland, almost any beach will be a great spot for catching the June Full Moon. Plains Perhaps harder to find in the rolling hills of Scotland, a grassy field or plain is another perfect choice of place for amateur stargazers to see the low-down Moon tonight. Large, flat areas of land are more commonly found in the lowlands of Scotland compared to the mountains of the Highlands. If you live nearby any farmland or wide open fields, you may be in proximity to a great viewing spot for the Strawberry Moon. Mountains or hills If you can't find any flat low land due to Scotland's vibrant landscape of rolling hills, you could consider climbing high enough that they won't obstruct the skyline. Scotland is home to countless hills, and some are particularly good for stargazing. For those in proximity to Glasgow, Ballageich Hill is just 25 minutes away by car, and Conic Hill is a short climb near Balmaha that's around an hour away from the city. However, if you're planning to climb a hill or mountain at night, it's vital to be well-equipped with good shoes, appropriate clothing, a torch (red-light torches are recommended to prevent disturbing wildlife) as well as a working phone in case of emergency.
