Update 2016: Since writing the article below, my family and I have lived through many July's in Anguilla. The weather is just slightly warmer than in June, with mostly clear skies and sparkling seas. It's a lovely time of the year to enjoy perfectly calm waters, empty beaches and a general vibe of tranquility before the Carnival excitement begins in late July/early August and before restaurants and hotels close up to take a breather at the end of August.
No one in my family can give you a first hand account of what Anguilla weather in July is like.
We have yet to experience such conditions!
From what I've heard?
Hot, hot, heat!
Average High in July: 88°F
Average Low in July: 78°F
Average Temp. in July: 82°F
Average Rain in July: 4"
Imagine June, with slightly more rain, with temperatures getting closer to the highs of August.
I'll write an update as soon as I've experienced Anguilla weather in July!
Anguilla travel tip (that was given to me): Bring clothing that can withstand heat.
