Traveller notes on Tobago in August

Other months in Tobago

Regulars are consistent that rain here typically arrives as a short, sharp shower that clears quickly rather than settling in for a full day, and that a whole vacation of all-day rain would be genuinely unusual even though this sits at the tail end of the wet season. Our row backs the real wetness behind that framing, 106mm of rain across a striking 18.8 days, alongside warm, humid conditions, 30.8C reading as a hot 33C at 79 percent humidity, over 24.1C nights, and a real 30.4 kph wind. Regulars flag the sea as noticeably choppier this time of year, not ideal for snorkeling even on an otherwise sunny day. One regular's caution is worth keeping in mind broadly: historical patterns aren't as reliable a guide as they used to be, with rain showing up in dry season and sun in wet season more often lately. The sea holds a warm 28.2C. The record: 10 hours of sun and one of the cleanest air readings in this project, AQI 39.

Regulars date the rainy season here from June, which makes May the last of the dry half and a common worry for people booking mid-month. Their description of what follows is the useful part: squalls of twenty or thirty minutes with sun behind them, cloud building through the day and rain in the afternoon, rather than a northern kind of wet day. Our May still reads dry in total, 59.2mm, though it falls across 12.8 days. Heat is the constant at 31.4C reading as 34C over 25.3C nights, with a 27.9C sea and a 30.9 kph trade wind. Rough water later in the year cancels boat trips; in May it mostly just cools the beach. The record: 11.4 hours of sun and AQI 53.

January sits inside the December-to-May dry season and regulars describe it as warm, sunny and dry - with wind as the caveat, since this is when the trades blow hardest and nobody here treats that as unusual. Our row makes the point numerically: 30.6 kph, which is a stiff breeze as a monthly average, and 30.4C reading as 33C without it feeling worse. Rain looks frequent at 14.3 days but totals only 47.1mm, about three millimetres each - passing showers rather than weather. The sea is 26.9C and generally calms after Christmas, though the boards will not promise it. The record: humidity 77 percent, 10.5 hours of sun and AQI 49.

April is the peak of Tobago's dry season - December to May, with April usually the driest of them - and the forum's caution is the standing tropical one: this is a rainforest island and rain can arrive at any time. The sea is the other variable, described as hit or miss at this time of year, though it generally calms down after Christmas. On crowds, March is the month regulars name for missing the masses, and the date to check against is the Tobago Jazz Festival in the last week of April, which takes the accommodation with it. Our row shows the trade wind at 30 kph. The record: 31.1C days that feel like 34C, 24.4C nights, 8.7 precipitation days carrying 34mm and a 27.2C sea.

  • Nature

    Leatherback nesting

    1 Mar – 31 Aug · usuallyTurtle nesting

    Leatherbacks haul out overnight on Turtle Beach and Stonehaven Bay from March, peak between April and July, and the hatchlings run through August. The main beaches are guided-only after dark, and the guides check permits.

  • Hazard

    Hurricane season

    1 Jun – 30 Nov

    Tobago sits at the southern edge of the belt and direct hits are rare enough that islanders name them by decade, but the tropical waves that cross it bring the wettest weeks of the year and cancel boat days. Source ↗

  • Festival

    Tobago Heritage Festival

    16 Jul – 1 AugMajor festivalCrowded

    Not one parade but a fortnight in which each village stages its own night: ole time wedding at Moriah, folk theatre, the salaka feast. You drive somewhere different every evening, which is the point of it. Source ↗

  • Holiday

    Emancipation and Independence

    31 Jul – 1 SepNational holidayClosuresCrowded

    Two public holidays a month apart, on 1 August and 31 August, and Trinidadians take the ferry over for both. Government offices shut and the Store Bay end is at its busiest of the wet season. Source ↗
