The climate in the city of Dax can be described as warm-temperate with noticeable oceanic influence. Thanks to its location in the southwest of France, extreme temperature fluctuations rarely occur here. The weather remains mild throughout the year, creating favourable conditions for wellness holidays and walks.

Winters in Dax pass without severe frosts: the average temperature in January and December holds at the level of 8-10°C. However, this season is distinguished by high humidity and frequent precipitation — rains can fall up to 16 days a month. Spring brings gradual warming, but an umbrella remains an important accessory for the traveller, as wet weather persists.

Summer is considered the most comfortable time for a visit. In July and August, the air warms up to a pleasant 26-27°C, and the number of rainy days drops to the minimum for the year. Autumn arrives smoothly: September often delights with almost summer-like warmth before the weather becomes cooler and rainier in November.

The temperature regime in Dax is distinguished by the mildness characteristic of southwest France. The coldest month of the year is traditionally January, when the average temperature is about 8.1°C. However, winters here cannot be called severe: even on the coolest nights, the thermometer averages at the mark of 5.1°C, and during the day the air often warms up to a quite comfortable 11-13°C. Thanks to this, even in the winter months, walks around the city remain pleasant, and severe frosts here are a great rarity.

Summer in Dax delights travellers with real warmth, but without extreme heat. The hottest months are July and August, when average daily highs reach 26-27°C. August is considered the peak of the summer season with an average temperature of 22.3°C. This time is ideal for those who love sunny weather: the air is warm enough for summer outfits, but humidity and heat rarely become unbearable.

It is also worth noting the comfortable temperature changes throughout the day. The difference between daytime and nighttime figures is usually from 4 to 9 degrees, which ensures pleasant freshness in the evenings. For example, in summer after a warm day, nights bring coolness with a temperature of around 18°C, which contributes to good sleep. Transitional seasons are also quite favourable: September often feels like a continuation of summer with daytime temperatures up to 24°C, and May already offers a comfortable 20°C during the day.

Precipitation in Dax falls quite regularly throughout the year, however, its character and frequency change noticeably depending on the season. Travellers should take into account that the wet period here lasts from late autumn to spring, while summer offers the driest and most comfortable weather. Even in warm months, an umbrella may be useful, but prolonged rains at this time are a rarity.

The "wettest" months are November and December, when the highest amount of precipitation is recorded, and rains fall for about half the month (about 15–16 rainy days). Since winter temperatures in Dax remain above freezing, precipitation falls predominantly in the form of rain, and snow is a rare guest. Spring can also be quite rainy, especially March and May, when the number of inclement days again reaches peak values.

The most favourable time for those who prefer clear skies comes in summer. The driest month of the year is considered to be July: at this time the amount of precipitation is minimal, and the number of rainy days decreases to 7. In August, the probability of precipitation increases slightly, but it is, as a rule, short-term in nature and does not interfere with enjoying a holiday in the French south.

When getting ready for Dax, first of all, take care of comfortable footwear. This city is conducive to long walks on foot, so you will need comfortable trainers or flat-soled boots. Considering that rains here are a frequent occurrence (the number of rainy days remains high even in dry months), it is sensible to choose waterproof shoes or treat them with water-repellent spray in advance. This will save your feet from dampness during walks along historic streets.

The climate in this region of France is mild, without extreme temperature changes, so the principle of layering in clothing will be the most practical solution. In winter, when the temperature holds around 10°C, you will not need a heavy fur coat — a demi-season jacket, scarf, and sweater will be sufficient. In summer, when the air warms up to a comfortable 26°C, give preference to light natural fabrics, but definitely take a windbreaker or cardigan with you for cool evenings or windy days.

Do not forget about important accessories that will make the trip more comfortable. A compact umbrella or light raincoat should be in your suitcase at any time of the year, as precipitation is possible even in July and August. In the summer season, the sun can be quite active, so be sure to take sunscreen, sunglasses, and headwear with you to protect yourself from ultraviolet rays during sightseeing.
