Best time to visit Réunion

La Réunion ist ein Ziel für Natur und Wandern mit dramatischen Bergkesseln. Auf der Südhalbkugel: kühlerer, trockener Winter (Mai bis November), feuchter Sommer mit Zyklonrisiko.

Réunion carries an average daytime temperature of about 24 °C across the year, which makes the climate warm on the whole. Warmest is February at around 27 °C by day, while July is the coolest month at roughly 20 °C. The overall climate score for the destination is 83 out of 100.

Purely on climate, the most rewarding months are May, September, October and November. All values on this page are historical monthly averages rather than a forecast, so treat them as the typical pattern you can plan around, not a guarantee for a specific week.

As a coastal destination in Afrika, Réunion follows the seasonal rhythm you would expect for its latitude, and the guide below breaks that rhythm down season by season, then by rain, sun, sea and travel style so you can match the month to what you actually want from the trip.

autumn (March to May) is warm at around 25 °C by day and changeable with about 9 rainy days per month. Nights cool to about 21 °C. The sea averages around 28 °C. This stretch suits city breaks and active trips without the heat.

winter (June to August) is pleasantly warm at around 21 °C by day and mostly dry with about 5 rainy days per month. Nights cool to about 17 °C. The sea averages around 24 °C. This stretch suits sightseeing, hiking and long days outdoors.

spring (September to November) is warm at around 23 °C by day and changeable with about 6 rainy days per month. Nights cool to about 19 °C. The sea averages around 25 °C. This stretch suits sightseeing, hiking and long days outdoors.

summer (December to February) is warm at around 26 °C by day and rainy with about 13 rainy days per month. Nights cool to about 22 °C. The sea averages around 28 °C. This stretch suits city breaks and active trips without the heat.

Day and night can feel quite different here. In the warmest month, February, days reach about 27 °C while nights ease to around 23 °C, a spread of roughly 4 degrees. The mildest nights come in February (about 23 °C), the coolest in August near 17 °C, so a light layer for the evening is worth packing outside high summer.

Relative humidity averages about 78 percent across the year, which is humid, so heat feels stronger than the numbers suggest. Humidity shapes how warm a given temperature actually feels, so it is worth weighing alongside the raw degrees.

Across the year Réunion records roughly 101 rainy days. The wettest month is January with about 14 rainy days, the driest is June with around 5. If low rain is your priority, the run of months around June is the safest bet. With a gap of roughly 9 rainy days between wettest and driest, the year has a clear wet and dry rhythm.

Sunshine peaks in December at about 9 hours a day and bottoms out in June near 5 hours. Longer days naturally line up with the drier, warmer part of the year.

The sea is warmest in February at about 28 °C and coolest in August near 24 °C. Comfortable swimming, from roughly 21 °C, is realistic in January, February, March, April, May, June, July, August, September, October, November and December, and the water turns genuinely warm (24 °C or more) in January, February, March, April, May, June, July, October, November and December. Remember the sea lags the air by a few weeks, so early summer can feel warm on land while the water is still catching up.

The same destination rewards different trips at different times. Based on the predefined monthly scores for Réunion:

Beach and swimming: the climate works best in May, October, November and December, when warm days and a swimmable sea line up.

City breaks and sightseeing: the climate works best in June, August, September and October, when temperatures are comfortable for walking without oppressive heat.

Hiking and active trips: the climate works best in June, July, August and September, when it is cooler and drier, better for effort.

Family holidays: the climate works best in April, May, October and November, when gentle warmth and low rain keep it relaxed with kids.

For packing, plan around light clothing. With up to 9 hours of sun a day at the peak, a hat and sunscreen earn their place in the bag.

If flexibility on dates is an option, the shoulder weeks just before and after the peak months tend to offer the best balance of good weather, lower prices and fewer crowds. The wetter stretch around January is worth planning around if rain would spoil your plans, while the driest window near June is the safest for outdoor days.

If you want the most reliable conditions, aim for May, September, October and November. The shoulder around these months usually keeps most of the upside with thinner crowds and lower prices. July is the least typical month for a warm-weather trip here, though it can still suit a city break or a quiet off-season stay. Match the month to your priority, whether sun, sea, low rain or sightseeing comfort, using the month-by-month table above.

In short, there is rarely a single right answer: Réunion shifts character across the year, and the best month is the one that lines up with the kind of trip you have in mind. Use the seasonal breakdown and the scores above to make that call with the numbers in front of you.
