San Agustin, located on the southeast coast of Gran Canaria the third largest island in the Spanish Canary Islands is classified as having a sub-tropical climate with dry summers and a brief and moderate rainy season in winter. Most markedly the town experiences pleasant and stable weather year round. While the town does receive warm-to-cool temperatures with near-perfect consistency, the warmest month of the year occurs in July.
Located amid the Atlantic Ocean off the west coast of Africa, the island town's annual climate is slightly more akin with the coastal cities of Morocco than with other Spanish towns. When compared to similar island resorts, such as Mallorca, this resort experiences more moderate and stable annual conditions. While Mallorca's average temperature drops as low as 10°C in the winter months, and shoots as high as 25°C in high summer, this island city's average temperature only varies between 18°C and 20°C throughout the year.
Because it is a coastal resort, the city will experience maritime influences, namely the occasional gust of strong winds.
With an annual average temperature that only varies from 19°C in one degree in either direction this island resort is a fantastic choice for good weather seekers any month out of the year.
Summer
From June until the end of August the resort experiences a slight temperature increase as the daily sunshine hours rise and peak in the month of July, the brightest month of the year, during which time guests will enjoy twelve hours of sun per day. This is certainly the sunniest season on the whole for the resort and thus a popular time of year to visit as holiday travellers seek out the island's sandy beaches and pristine waters. Guests on the island during this time of year will do well to take appropriate skincare precautions and apply sun-cream multiple times a day if they are going to be outside during the bulk of the daylight hours. Because the Canary Islands are nearer to the equator than all of Europe, UV rays will be harsher than elsewhere on the main continent.
In addition to being the sunniest time of year, summer is also the dry season on the island. Throughout the entire three months of summer there is on average only 1mm of accumulated rainfall in the city. This is another factor contributing to this resort's popularity. Visitors can rest assured that their holiday won't be affected by rain.
This time of year also brings rising average sea temperatures. Beginning at the end of spring the ocean temperatures rise from 20°C to 22°C by the end of August. Ocean bathing should be ever more comfortable the later you plan your visit in the summer months.
Autumn
This season sees the most drastic drop in average temperature. However, that drop in temperature is extremely mild as the average temperature falls from a summertime high at 20°C to the annual low average of 18° beginning in October, which registers as the coldest month of the year on average. This only slight variation in seasonal weather is typical of the island's sub-tropical climate.
Daylight hours only decrease slightly, starting the season in September with ten hours per day and falling to eight hours of sunshine per day in November.
The most notable change in the season is increased rainfall as the dry season ends and autumn sets the stage for the winter rainy season. Across the season's three-month span, an average of 27mm of accumulated rainfall collects. This occurs across 18 interspersed days throughout the period. While this can be considered a huge percentage increase in rainfall compared to the previous season, it represents nonetheless a relatively dry climate when compared to global averages. Visitors shouldn't be overly concerned with rain conflicting with plans during their holiday.
Arrive early in the season to enjoy some of the year's warmest ocean temperatures. September and October share the claim of warmest average sea temperature with Atlantic waters on the coast registering at 23°C. While the season doesn't offer the hottest daytime temperatures to warm swimmers emerging from a dip in the sea it is still possible to enjoy an ocean swim due to the high water temperatures.
Winter
Temperatures remain steady in early winter before beginning to rise again by the new year. Winter continues to be a popular time to visit the island resort due to its high temperatures and ample sunshine in comparison with much of the globe throughout winter.
This time of year does mark the island's rainy season. In December alone 37mm of rainfall accumulates across a span of nine days. The average rainfall declines month by month thereafter until the end of the season. Here is another instance where the resort's version of extreme weather is mild by comparison with other resorts throughout the world. The rainiest month in Phuket, Thailand a popular tropical resort destination in Southeast Asia is July, which experiences 300mm of rainfall across nineteen days on an annual average.
The fewest daylight hours shine throughout the winter months, with December having the years least sunshine with seven hours of average daily sunshine throughout the month. By January daylight hours begin to increase again with each consecutive month.
By January the average sea temperature returns to its annual low at 19°C.
Spring
The comfortable temperatures of winter continue to hold throughout spring while rainfall decreases and more sunshine graces the resort. The average temperature throughout the entire three months of the season keeps to a rosy 19°C. The average high temperatures throughout the season reach 24°C while the low drops only to 14°C in each month, except for May, when lows dip to 13°C.
March is the rainiest month of the season with 12mm of rainfall accumulating across six days. April and May both experience an abundant amount of sunshine with eleven hours of average daily sunshine across the two-month span.
Sea temperatures don't begin to rise until late spring, when they reach 20°C in May.
Weather Hazards
Dust storms present the most disruptive conditions on the island. Particularly through February and March guests should be aware of the potential hazard and know to retreat indoors if the air becomes clouded with dust. You will usually see the storm approaching and will have time to take proper precautions. People with asthma or other breathing conditions suffer most from the dust storms, but by taking shelter quickly you can prevent any undue stress and problems. A heavy concentration of dust in the air can also cause eye irritation for anyone caught in the storm.
When winds are low during winter air pollution can build in the cities causing discomfort for individuals with respiratory conditions. Stay near the coast to ensure you have plenty of fresh sea air to breath and enjoy.
