Our guide to the weather in Saint Lucia during July
St Lucia is a lush tropical Caribbean island and is very warm all year round. We've looked at the most up-to-date weather data for Saint Lucia, covering the last 12 years up to 2026, plus we've asked our team of travel bloggers for their first-hand experiences in order to answer the most frequently asked questions about Saint Lucia weather in July.
Is July hurricane season?
The Caribbean hurricane season runs from 1st June to 30st November. However, it's relatively rare for hurricanes to form early in the season. Even in the peak hurricane month of September, the chances of your holiday being affected are very small. In the unlikely event that a hurricane does track towards St Lucia, forecasting of North Atlantic storms is highly advanced and you'll get plenty of warning and instruction.

How warm is it in Saint Lucia during July?
The temperature is extremely stable in July with average highs of 29℃ and lows just 3℃ lower at 27℃. Of course, the high humidity will make it feel even hotter. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.
Does it rain in Saint Lucia during July?
On average, there will be 6 rainy days during the month, amounting to 138.5mm in total. That's a significant amount of rain. For comparison, the wettest months in the UK typically sees between 80mm and 100mm, depending on where you are. Due to the high temperature and humidity, you might expect lots of thunderstorms, however they're actually fairly infrequent at this time of year. On average, July will see just 2 days that produce a storm.
Is it windy in Saint Lucia during July?
Expect moderate breeze becoming stronger at times during July, with occasional gusts up to 20mph. The high humidity and warm temperature will make the breeze feel warm, so any cooling effect will be limted.
How warm is the sea in Saint Lucia during July?
The water around Saint Lucia reaches a very pleasant 28℃ during July. This is very warm, and will feel bath-like. People who normally feel the cold will find this temperature perfectly acceptable. The hot air temperature and relatively high humidity will mean that you will feel comfortably warm when coming out of the water.
