The climate in San Jose del Cabo is characterized as arid (desert), which means hot and very dry weather throughout most of the year. The city enjoys abundant sunshine, and temperatures remain warm or hot year-round. Rainfall here is an extremely rare phenomenon, with most months recording 0 mm or just 1 mm, making it an ideal destination for those seeking a guaranteed sunny holiday.

Although there are no sharp seasonal temperature fluctuations, two main periods can be distinguished. From November to April, the weather is milder and exceptionally dry, with average temperatures around 19-23°C – this is a very comfortable time to visit. From May to October, it becomes noticeably hotter, especially during the summer months (June-September), when average temperatures rise to 27-29°C, and daytime highs often exceed 31-32°C. Interestingly, August and September see a slight increase in the number of rainy days (up to 14-15 days), yet the total rainfall remains minimal (4-5 mm), indicating very light and short-lived showers.

Overall, the weather in San Jose del Cabo is very predictable: expect plenty of sun and warmth practically all year round. Even during the "coolest" winter months, it is warm and sunny here, while summer offers true desert heat. The slight increase in the probability of precipitation at the end of summer is unlikely to seriously affect your plans, as rains are usually light and brief. The main things to take care of are sun protection and light clothing at any time of the year.

San Jose del Cabo experiences a warm desert climate with pleasant temperatures year-round. The annual range of average temperatures fluctuates from approximately 19.6°C in January to 28.7°C in July and August. The hottest months are traditionally July and August, when the average maximum temperature rises to 32.4-32.9°C, and the minimum night-time temperature stays around 24.5-24.9°C. The coolest months are January and February, with an average temperature of about 19.6-19.8°C. During this time, daytime highs reach a comfortable 25.6°C, while night-time lows drop to 13.7-14.0°C.

The summer period, from June to September, is characterized by hot weather. Daytime temperatures consistently exceed 31°C, and nights remain very warm, with minimums above 22°C. Humidity also increases during this time, especially in August and September, which can create a sultry sensation. The winter months, from December to February, offer mild and pleasant conditions. During the day, the air temperature usually hovers around 25-26°C, which is ideal for walking and outdoor activities, while evenings and nights become noticeably cooler, with temperatures dropping to 13-15°C.

Throughout the year, noticeable temperature fluctuations between day and night are observed in San Jose del Cabo. The difference between the average maximum and average minimum temperature is often 10-13°C, especially during the drier months from March to May and November to December. This means that even after a hot day, the evening can bring a pleasant coolness. In the hottest summer months (July-September), this difference smooths out somewhat but remains noticeable, amounting to about 7-9°C. Travellers should take these daily variations into account and have a light jacket or sweater with them for evening walks, especially during the winter period and the off-season.

An arid climate prevails in San Jose del Cabo, and precipitation here is a rather rare phenomenon throughout most of the year. The city has a distinct dry season that lasts from December to May. During this period, especially from March to May, rain is practically absent: on average, there is not a single rainy day and 0 mm of precipitation falls during these three months. January, February, and December are also extremely dry, with zero precipitation and just one "wet" day per month.

A slight increase in precipitation is observed in the summer and early autumn months, forming a short and not very intense wet season. The peak of this season falls in August and September. In August, an average of 4 mm of precipitation falls, distributed over approximately 15 days with precipitation. September is the "wettest" month of the year in terms of total rainfall (5 mm), with about 14 rainy days counted. July also shows some increase in humidity with 1 mm of precipitation and approximately 6 days when rain is possible. It is important to note that even in these wettest months, the total amount of precipitation remains very low, indicating that the rains are likely light or short-lived in nature.

Thus, the driest months in San Jose del Cabo, when the probability of rain is practically zero, are March, April, and May. On the other hand, August and September are considered the wettest, but even at this time, the total amount of rainfall is small. Snow is not characteristic of this region due to high temperatures year-round.

When planning a trip to San Jose del Cabo, remember that the city is distinguished by a warm and predominantly sunny climate all year round. The basis of your wardrobe should consist of light, breathable items made from natural fabrics, such as cotton T-shirts, shorts, sundresses, and linen shirts. Do not forget swimwear for a beach holiday. The most important accessories will be sunscreen with high SPF, headwear (a hat or cap), and quality sunglasses, as the sun here can be very intense.

Although the weather in San Jose del Cabo is generally warm, in the winter months (from December to February), evenings can be cool, with an average minimum temperature of around 14-15°C. Therefore, it is recommended to bring a light jacket, cardigan, or sweater. The principle of layering in clothing will be very useful. In summer, especially in August and September, when the average maximum temperature reaches 32°C and the number of days with precipitation increases (although the total amount is small, about 4-5 mm per month, but up to 15 rainy days), a light waterproof windbreaker or a compact umbrella will come in handy in case of short-term rains.

Besides clothing, pay attention to your choice of footwear: comfortable sandals or flip-flops for the beach and casual walks, as well as closed light shoes (for example, loafers or espadrilles) for longer excursions or evening outings. In the summer months, especially during the period from June to September when humidity can be higher, insect repellent will not be amiss. If you plan to visit restaurants with a dress code, pack one or two smarter outfits.
