Weather in Lyon in June

Prime time. June is about as good as Lyon gets. Highs average 25.6 °C, lows 14.2 °C, and rain falls on 12 days — nothing in the month is working against you.

June ranks 2 of 12 in Lyon. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 12 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 38.3 °C and the coldest night fell to 4.9 °C, and the wettest single day dropped 29 mm — roughly 43% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 104 mm against 14 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 67 mm average is a reasonable planning figure, not a promise.

Wind is light at 8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How June sits in the year

The month is on the way up: 4.7 °C warmer than May, and July adds another 2.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in June

June is at or near the longest days of Lyon's year: 15.7 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 27.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

June in Lyon versus nearby

If Lyon is one option among several, the nearby comparison is worth making. Annecy is close enough to be a coin toss — 2.1 °C cooler, 3 days more rain. Chamonix-Mont-Blanc is close enough to be a coin toss — 5.2 °C cooler, 4 days more rain.

So: June is effectively as good as it gets here — 6 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
