Daytime High Temperatures
As you might expect, and by nearly every measure, January is the coldest month of the year in Fuerteventura. Average daily highs are just under 21°C – although it will often feel hotter on south-facing sun terraces that are sheltered from the wind (usually the case in Fuerteventura). Some days will, of course, be hotter, and there are usually some 23°C or 24°C days during January.
At night, temperatures in most places along the coast typically drop to about 14°C or 15°C, perhaps a degree or so warmer in sheltered locations in the south such as Morro Jable. Inland, temperatures drop a few degrees more, especially in the mountains. Some years are hotter or colder than others, and the lowest nighttime temperature ever recorded at the airport is 9°C. The usual advice to visitors is that shorts and t-shirts are fine during the day, but you might need a cardigan or light jacket at night.
Rain in January
January is, on average, the second rainiest month of the year (after December). However, remember that Fuerteventura is a desert island, so the second rainiest month only gets 2-3 days of rain (over 1mm) and a total of just 12.9mm. From experience, I would say that the rainy days tend to come on consecutive days as a weather system slowly passes through the islands.
There are some clouds on most days, with, on average, just 2 overcast days during the month. The north of the island is cloudier than the south, something worth bearing in mind at this time of year if you are looking to maximise sunshine hours during your holiday.
January is not usually the windiest month of the year on the island, though there can be some blustery days if there is stormy weather.
The temperature of the sea is about 19°C in January, so okay for short dip in a shallow bay on a sunny windless day, but you will probably require a light wetsuit if you plan to spend any time in the water surfing, snorkelling or diving.
Episodes of dust being blown over from the Sahara are more common at this time of year. Although searing temperatures are unlikely (the Western Sahara is cool at this time of year), the thick dust is quite unhealthy, and the government may advise people to avoid outdoor exercise.
In January, the sun rises just before 8am and sets at about 18:20.
