Lewa Wildlife Conservancy's location on the Laikipia Plateau, at a mean altitude of 1,700 metres, creates a temperate climate with two distinct dry seasons and two rainy seasons. An understanding of these seasonal patterns is necessary for planning a safari in 2026 and selecting appropriate clothing for the variable conditions.
Annual Rainfall Cycle at Lewa Wildlife Conservancy in 2026
The conservancy's bimodal rainfall pattern consists of two wet periods separated by dry spells. The "long rains" deliver the highest precipitation volumes and are followed by a long dry season. The less intense "short rains" arrive later in the year, preceding a shorter dry season. This cycle directly affects vegetation growth and the navigability of certain tracks within the conservancy, particularly on black cotton soil.
Lewa's Primary Dry Seasons in 2026
Two main dry periods provide consistent conditions for safari activities. The first is from January to February, and the second, longer period extends from June through to September. During these months, precipitation is low. August is typically the driest month, receiving an average of only 30 millimetres of rain.
The Long Rains Period in 2026
The long rains are forecast from March through to May. April is the wettest month, with average precipitation reaching 160 millimetres. This volume of rain can make some dirt tracks difficult to traverse. Humidity levels also increase during this period, averaging around 80%.
The Short Rains Period in 2026
The short rains generally occur from October to December. Precipitation is less prolonged than during the long rains, often arriving as heavy afternoon thunderstorms that pass within a few hours. November is the peak month for this season, with an average rainfall of 130 millimetres.
Seasonal Temperatures at Lewa Wildlife Conservancy in 2026
Lewa's high altitude causes a wide diurnal temperature range, with a significant difference between daytime and night-time temperatures. Daytime conditions are mild year-round, but mornings and evenings are consistently cool. This daily fluctuation occurs regardless of the season and is a key consideration for packing.
Dry Season Temperatures in Lewa 2026
During the dry seasons, daytime temperatures average 27°C in January and February, and between 24°C and 26°C from June to September. Humidity is lower, averaging 55-60%. Clear skies cause temperatures to drop sharply after sunset, making warm layers a necessity for early morning and evening activities.
Wet Season Temperatures in Lewa 2026
The wet seasons have slightly cooler daytime temperatures due to greater cloud cover. From March to May, average highs are between 22°C and 25°C. The October to December period sees averages of 23°C to 25°C. Humidity is higher, often reaching 80%, which can make the air feel warmer than the recorded temperature.
Characteristics of Lewa's Dry Seasons 2026
The two dry seasons provide the most predictable weather for safari planning. Both periods are defined by low precipitation and generally clear skies, which aids in wildlife observation.
Early Year Dry Period January to February
This short dry season offers good safari conditions. Rainfall averages 35-45 millimetres, and daytime temperatures are around 27°C, creating warm and dry days. This is a period when weather-related interruptions to activities are infrequent.
Mid Year Dry Period June to September
This is the longest and most pronounced dry season. Rainfall drops to its lowest annual levels, with August averaging just 30 millimetres. Temperatures average between 24°C and 26°C, and the lower humidity contributes to drier air conditions.
| Period | Month | Average Rainfall (mm) |
|---|---|---|
| Long Rains Peak | April | 160 |
| Short Rains Peak | November | 130 |
| Main Dry Season Low | August | 30 |
A Comparison of Lewa's Long and Short Rainy Seasons 2026
While both rainy seasons deliver moisture, their characteristics and effect on safari logistics differ. The long rains are more sustained, whereas the short rains are typified by dramatic but brief downpours that often clear up quickly.
Understanding Lewa's Long Rains from March to May
This period brings the heaviest and most consistent rainfall of the year, peaking in April at 160 millimetres. The rain can last for several hours at a time, directly affecting ground conditions. Travel during these months requires a flexible itinerary, as certain routes may become temporarily impassable.
Understanding Lewa's Short Rains from October to December
The precipitation during this season is typically less disruptive to daily schedules. Rain often arrives as an intense afternoon or evening thunderstorm which recedes to reveal clear skies. While November records 130 millimetres of rain, the showers are less likely to affect a full day of activities.
Practical Packing Advice for Lewa's Climate
Packing for a safari in Lewa requires clothing suitable for a wide range of temperatures within a single day. The high altitude is the primary factor driving this need for versatile layers. Sun and rain protection are also recommended throughout the year.
Layering for Diurnal Temperature Changes
The temperature difference between an early morning game drive and midday is substantial. A layered clothing system is the most practical approach.
- A warm fleece or an insulated jacket is needed for cool mornings and evenings.
- Lightweight shirts and trousers in neutral colours are suitable for warm midday hours.
- A scarf or buff provides warmth in the morning and can be used for sun protection later.
Rain Protection for Lewa Safaris
A waterproof jacket is a useful item to pack, even when travelling in a dry season, as unexpected showers can occur. During the wet seasons, waterproof trousers are a practical addition for staying dry during outdoor activities.
Sun Protection at High Altitude
The sun's UV radiation is more intense at Lewa's altitude. Protective measures are important for all daytime excursions. A wide-brimmed hat, high-SPF sunscreen, and sunglasses should be used to prevent sunburn.
