Paris weather has a habit of changing its mind. Sun one minute, rain the next, in any season, that's just what an oceanic climate does, and I've seen the temperature swing by 25°F in a single day. So if you're already wondering which weather app to trust before you land, good instinct, it's one of the most useful things you can sort out before your trip.
The best weather app for Paris is Weather & Radar, with AccuWeather as an equally reliable alternative. Default phone apps (iPhone Weather, Google, Pixel Weather) fall short in Paris’s changeable oceanic climate. Whatever app you use, forecasts become reliable about 5 days ahead and solid at 2 to 3 days.
Key takeaways:
Your phone’s default weather app (iPhone Weather, Google or Pixel Weather) isn’t reliable enough for a trip to Paris.
Weather & Radar is the best weather app for Paris, with a clearer rain radar than AccuWeather and easy-to-find UV, pollen and air quality maps.
AccuWeather is an equally reliable alternative for Paris, with a more modern design but ads that interrupt the forecast.
Both apps are free with ads. There's no need to subscribe to paid 10-day weather forecasts: in Paris, 10-day forecasts aren't reliable.
Paris forecasts become reliable about 5 days ahead and solid at 2 to 3 days, so pack for the season next to yours too.
Skip Your Phone's Default Weather App
Your phone’s built-in weather app, whether iPhone Weather, Google or Pixel Weather, isn’t reliable enough for a trip to Paris.
I have an iPhone, I've lived in Paris for years, and the native Weather app just isn't reliable at all in Paris. Apple bought Dark Sky in 2020, the app everyone loved for its precision, then shut it down in 2023, and honestly, the accuracy hasn't been the same since. That's not just me saying it, it's a common complaint!
It's not an iPhone thing either. On Android, it's not just the Google weather widget, there's also Pixel Weather, and in my experience neither is reliable enough, they're probably pulling from the same source anyway. So whichever phone you have, don't count on whatever came pre-installed for your Paris trip.
The 2 Apps That Actually Work: AccuWeather And Weather & Radar
Weather & Radar and AccuWeather both give reliable forecasts for Paris, and Weather & Radar is my pick for its clearer rain radar and its UV, pollen and air quality maps. But if you've already got AccuWeather on your phone, don't worry, it'll do the job just as well. Here's how they compare:
| AccuWeather | Weather & Radar | |
|---|---|---|
| Data reliability | ✅ Excellent | ✅ Excellent |
| Free plan | ✅ Free, with ads (fair enough for a free app) | ✅ Free, with ads (fair enough for a free app) |
| Layout | Vertical scroll, ads interrupt the scroll mid-information | ✅ No ads interrupting the weather info on the main page (horizontal scroll) |
| Rain radar | Hard to read | ✅ Clear |
| App design | ✅ Modern | Dated |
| Extra maps | Pollen and air quality indices, tucked away, no UV found | ✅ UV, pollen, and air quality indices, clearly displayed |

Can You Trust A 15-Day Or 30-Day Forecast For Paris?
Sorry, but no: a 30-day forecast for Paris isn’t reliable, and a 10-day forecast only gives a loose trend.
I know it's a question you keep asking, and I get it, when I look at how many people search for a 30-day forecast for Paris every month, it's a lot, so you're definitely not the only one wondering. The problem is, it just doesn't work, not here. Paris has an oceanic climate, which means changeable by definition, there's no long dry or hot stretch to lock a forecast onto, and climate change has only made long-range models less steady. A 30-day forecast isn't worth opening the app for. 15 or 10 days out, treat it as a loose trend, not something to pack around. Real reliability starts around 5 days out, and it's genuinely solid at 2 to 3 days. AccuWeather even pushes a premium subscription for its 10-day forecast. Don't fall for it, I just covered this, 10 days isn't a reliable forecast.
Whatever season you visit Paris in, pack for the season next to it too: that’s the Next-Season Rule. A summer trip can still hand you a spring-cool or autumn-grey day. Spring can dip into a day or two of winter. Even the middle of winter can surprise you with a day that feels like early summer. So no wool hat in July, and no short skirt in January (well, unless you really want to), but pack like you might get more than one season during your stay, because in Paris, you probably will.
So here's the takeaway: don't count on your phone's default weather app. My top recommendation is Weather & Radar, but AccuWeather will do the job just as well if you've already got it installed, or if you simply prefer it… No hard feelings!
