Weather FAQ
Quick answers about the weather today and tomorrow, reading a forecast and the radar, the seasons in India, and how to get the most out of MyWeatherToday.
Weather today and tomorrow
What’s the weather?
MyWeatherToday shows the weather where you are the moment the page opens. It finds your approximate location by itself, or you can press “Use my location” for a precise fix or search any city or town in the world. You get the temperature now, what it feels like, the sky, wind, humidity, UV index, air quality and a 15-minute rain outlook for the next few hours.
What is the weather today?
The weather today is the current conditions plus the rest of the day: the high and low, the chance and amount of rain, wind and gusts, the UV index, and sunrise and sunset. The home page gives you all of it for your location, and the hourly forecast breaks today into single hours so you can see when the warmest part of the afternoon or the first shower is due.
What’s the weather tomorrow?
Tomorrow’s high, low, rain chance and wind are in the 14-day list, and the hourly page shows tomorrow hour by hour, so you can see whether rain is a morning shower or an all-day soaking. After the current hour, a next-day forecast is the most reliable forecast there is: highs and lows are usually within a couple of degrees, and the timing of rain within a few hours.
Will it rain tomorrow?
Open the hourly forecast and read tomorrow’s rain row. It shows the chance of rain and the expected amount for every hour, which tells you far more than a single daily icon. A high chance of a fraction of a millimetre is drizzle; a moderate chance of 10 mm or more is a proper downpour worth planning around. Check again in the evening, because the forecast for the next day sharpens as it gets closer.
What’s the weather this weekend?
Saturday and Sunday are in the 14-day forecast. If the weekend is one to three days away you can trust the detail, including the hour rain starts. Four to seven days out, trust the overall pattern, such as a warm, dry spell or a cold front, and expect exact temperatures to move by a few degrees as the days get closer.
How often is the forecast updated?
Current conditions and the short-range forecast refresh about every fifteen minutes. The weather models behind the longer range run several times a day, so the 7 to 14-day outlook changes a few times between morning and night.
Reading the forecast
How do I read a weather forecast?
Start with three numbers: the temperature (and what it feels like), the chance of rain with its expected amount, and the wind. Then look at timing in the hourly view, because a daily summary hides when things happen. Finally, match your trust to the range: the next three days are detailed and dependable, days four to seven show the pattern, and days eight to fourteen show only the trend.
What does a 40% chance of rain mean?
It means there is a 40% chance that at least a measurable amount of rain falls at your location during that period. It does not mean it will rain for 40% of the day, or over 40% of the area. Check the expected amount too: a high chance of a light drizzle matters less than a moderate chance of a thunderstorm.
How accurate is a 10-day or 14-day weather forecast?
NOAA’s rule of thumb is that a five-day forecast is right about 90% of the time, a seven-day forecast about 80%, and a ten-day forecast only about half the time. Use days 8 to 14 for the trend (warmer, cooler, wetter, drier), not for exact temperatures or the hour rain starts.
What does the “feels like” temperature mean?
Feels like is how warm or cold the air seems on exposed skin once wind and humidity are taken into account. Wind strips heat away, so a cold, breezy morning feels colder than the thermometer says. Humid air slows sweat from evaporating, so a hot, sticky afternoon feels hotter. When the two numbers differ a lot, dress for the feels-like figure.
What is the dew point, and why does it matter?
The dew point is the temperature at which the air would become saturated and dew would form. It is a better comfort guide than relative humidity, which rises every night simply because the air cools. A dew point below about 13°C (55°F) feels dry, 16 to 18°C (60 to 65°F) starts to feel sticky, and above 21°C (70°F) is properly muggy.
What is a safe UV index?
A UV index of 0 to 2 is low and needs no special care for most people. From 3 upwards, sunscreen, sunglasses and a hat are worth it, especially around midday. At 8 and above, fair skin can burn in well under half an hour, even on a day that feels cool or hazy.
What is a good air quality index (AQI)?
MyWeatherToday shows the US AQI. A reading of 0 to 50 is good, 51 to 100 is moderate, 101 to 150 is unhealthy for sensitive groups such as children, older people and anyone with asthma, and above 150 is unhealthy for everyone. Fine particles (PM2.5) from traffic, crop burning or wildfire smoke are usually what pushes the number up.
Why is the forecast different from my thermometer?
A forecast describes a grid cell a few kilometres wide, measured two metres above open ground in the shade. A thermometer on a sunny wall, a balcony or a car dashboard reads warmer. Valleys also run colder on clear nights, city centres stay warmer after dark and hills catch more rain. If your spot is consistently a few degrees off, that is your microclimate.
Weather radar and maps
How do I see the weather radar near me?
Open the weather map. It centres on your place, shows live rain radar from national radar networks, and lets you play the last couple of hours forward so you can see which way showers are moving and how fast.
What do the colours on the weather radar mean?
The colours show how strongly rain, snow or hail reflects the radar beam. Light green is light rain, yellow and orange are heavy showers, and red or purple usually means torrential rain or hail inside a thunderstorm. Play the animation to see the direction and speed of movement, which tells you when it will reach you.
Why does the radar show rain when it is dry outside?
Sometimes rain evaporates before it reaches the ground, which meteorologists call virga. Far from a radar site, the beam is also high above the ground, so what it sees may fall elsewhere or dry out on the way down. Close to the radar the opposite happens and it can miss low drizzle. For this evening and tomorrow, use the rain forecast layer instead.
Weather in India and Indore
What’s the weather today in India?
India is too big for a single answer. On the same winter day Srinagar can be below freezing while Chennai is above 30°C, and during the monsoon one state can flood while another stays dry. Search for your city or town, or let MyWeatherToday find your location, to see the weather today for exactly where you are.
What are the seasons in India?
The India Meteorological Department uses four seasons: winter from January to February, the hot pre-monsoon summer from March to May, the southwest monsoon from June to September, and the post-monsoon season from October to December, when the northeast monsoon brings most of the year’s rain to Tamil Nadu and coastal Andhra Pradesh.
When does the monsoon arrive?
The southwest monsoon normally reaches Kerala around 1 June and spreads north to cover the whole country by about 8 July. It starts withdrawing from northwest India in mid-September. Within the season there are often “breaks” of a week or more with little rain, so a dry spell in July does not mean the monsoon has failed.
What is the weather like in Indore today?
Open the Indore forecast for the temperature right now, today’s high and low, rain chance, wind and air quality. Indore sits on the Malwa plateau at about 550 metres, which is why its evenings are usually cooler and breezier than those of cities on the plains.
Is Indore hot or cold?
Both, depending on the season. April and May are hot, with afternoons often around 40°C. The monsoon from late June to September brings most of the year’s rain and cooler days. Winter, from December to February, is mild and dry, with pleasant days in the mid-20s °C and chilly nights that can drop below 10°C.
Will it rain in Indore tomorrow?
Check the hourly forecast for Indore, which shows the chance of rain and expected amount for every hour of tomorrow. Outside the monsoon months rain is rare. During the monsoon, a run of dry days usually means a break in the monsoon, when the rain-bearing systems shift north towards the Himalayas or stall over the Bay of Bengal, and rain tends to return when the next low-pressure system moves inland.
Weather basics
What is weather?
Weather is the state of the atmosphere at a particular place and time: how hot or cold it is, whether it is wet or dry, calm or windy, clear or cloudy. It changes from hour to hour and day to day, and is measured with temperature, humidity, air pressure, wind, cloud cover and precipitation.
What is the difference between weather and climate?
Weather is what is happening now or over the next few days. Climate is the average pattern of weather in a place over many years, usually 30. A heavy shower in Indore is weather; Indore getting most of its rain between June and September is climate.
What are the main types of weather?
The common types are sunny or clear, partly cloudy, overcast, fog and mist, drizzle, rain, thunderstorms, snow, sleet, hail, windy weather, heat waves and cold waves. Severe types include cyclones, hurricanes and tornadoes, dust storms, blizzards and freezing rain.
What factors affect the weather?
Five main factors drive the weather: heat from the sun, air pressure, wind, humidity and cloud cover. Geography shapes how they play out. Latitude sets how much sunlight a place gets, altitude makes air cooler, nearness to the sea softens extremes, and mountains force air to rise and drop rain on one side.
How does the weather forecast help us?
A forecast helps you decide what to wear, when to travel, and whether to carry an umbrella. Farmers use it to time sowing, irrigation and harvests, airlines and shipping use it to plan routes, and warnings for heat waves, cyclones, floods and storms give people time to stay safe.
